Hydroxyoctadecadienoic acid (HODE) is one of hydroxy fatty acids that has anticancer activity. HODE was previously produced by chemical synthesis or bioconversion from linoleic acid. This is the first paper reported production of HODE by Curvularia lunata an endophytic fungi of Cibotium barometz. Various carbon and hydrogen sources have been tested for their effects on the production of HODE by C. lunata. Glucose, lactose, maltose, xylose, and sucrose were used as carbon sources, while yeast extract, monosodium glutamate, urea, and NH4Cl were used as nitrogen sources. Fermentation was done using 100 ml medium in 250 ml Erlenmeyer flask at 150 rpm, 28 oC for 10 days. HODE products were analyzed by high pressure liquid chromatography using C18 coloumn and eluted by gradient system of acetonitril-water from 15% to 100%. Glucose and monosodium glutamate were found to be the best carbon and nitrogen source. The optimum concentration of glucose and monosodium glutamate for the production of HODE were 10 mg L-1 and 12 mg L-1 respectively.

Combined fungal and microwave pretreatment is an attractive method to alter carbohydrate and lignin structure of lignocellulosic materials for improving hydrolysis process in order to convert these lignocellulosic materials to bioethanol. This study was conducted to obtain the information on the characteristic changes of cellulose and lignin after combined biologicaland microwave pretreatment of Betung Bamboo. Based on our previous research, incubation for 30 days both for 5 and 10% liquid-inoculum loading of white rot fungi, Trametes versicolor, was chosen as the fungal pretreatment prior to microwave pretreatment at 30% power level for 5, 10 and 12.5 minutes. The evaluation of characteristic changes after combined pretreatment was performed using the analysis of FT-IR spectroscopy, X-Ray diffraction and SEM.FTIR spectra demonstrated that the combined pretreatment only affected the decrease of intensity bands of FTIR spectra with increasing microwave irradiation time, without any changes in the functional groups.This band intensity decrease occured on unconjugated bonds of carbohydrate peaked at 1736 (C=0 in xylan), 1373 (C-H deformation in cellulose and hemicellulose), 1165 (C-O-C vibration in cellulose and hemicellulose), and 895 (C-H deformation or C-O-C stretching at Î²-glicosidic linkage characteristic in cellulose) cm-1. The pretreatment decreased the hydrogen bond stretching of cellulose and the linkage between lignin and carbohydrate. This decrease of hydrogen bond was associated with crystallinity of bamboo cellulose,ilustrated by occurring structural changes.Â Syringil propane units were more soluble than guiacyl moieties.Â The crystallinity of cellulose tended to increase slightly due to the cleavage of the amorphous fraction. SEM images illustrated that the pretreatment disrupted the fiber structure while the longer microwave irradiation, the greater fiber degradation level. Prolonging microwave irradiation on 5% inoculum loading decreased lignin degrading ability. Crystalline allomorph of 5% inoculum loading for 10 minutes showed that IÎ² (triclinic) structure of cellulose has transformed into monoclinic (IÎ±) structure.Key words: betung bamboo, combined biological andmicrowave pretreatment, cellulose and lignin changes, FTIR, SEM, XRD

Biodegradation of the bioplastic composite based on cellulose from oil palm empty fruit bunches was investigated in this study. Microbes consortium from landfill soil collected from top soil were used as the inoculums for the biodegradation process. Biodegradation test of the bioplastic from oil palm empty fruit bunch samples compared with oxodegradation and conventional plastic samples were conducted in the glass jar. The biodegradation rate was evaluated from CO2 generated from the biodegradation process and absorbed by 0.1 N sodium hydroxide solutions. The generated CO2 was titrated with 0.1 N HCl and using phenolphthalein (PP) followed by methyl oranges indicator. The results showed that the highest CO2 production on landfill soil indicating the highest rate of biodegradation was found on bioplastic from oil palm empty fruit bunch followed by oxodegradable plastic and conventional plastic. The rate of biodegradation for bioplastic from oil palm empty fruit bunch, oxodegradable plastic and conventional plastic were 0.067mg CO2/day, 0.052 mg CO2/day and 0 mg CO2/day, respectively.

The aim of this research was to find out the effect of substrate concentrations (COD) of vinasse and the length of fermentation time to bio-hydrogen gas production using agent fermentation of photosynthetic bacteria, Rhodobium marinum. The production of bio-hydrogen was examined by varying COD of vinasse (10,000; 20,000; 30,000; 40,000; 50,000 mg COD/L) at certain fermentation time in the third, sixth and ninth day. The highest Hydrogen gas was obtained at ninth day of fermentation (82.66±18.6 mL). The highest Hydrogen Production Rate (HPR) and COD removal rate were obtained at concentration 50,000 mg COD/L, namely 109.98 mL H2/L/d and 1437.66 mg COD/L/d, respectively. Thus it can be concluded, the concentration of substrates (COD) from vinasse and the length of fermentation time have an effect on production of bio-hydrogen gas using Rhodobium marinum

Sunaryanto et al, 2019. Optimization of Penicillium lagena Medium Cultivation on Antifungal Pathogen of Phellinus lamaoensis using Response Surface Methodology. pp. 410-420. Phellinus lamaoensis (Murr.) Hein is fungal pathogen that can cause brown root rot disease in cocoa, tea, rubber, and coffee plants. Endophytic fungi, Penicillium lagena, isolated from bandotan (Ageratum conyzoides Linn.), medicinal plant, is able to inhibit the growth of pathogenic, P. lamaoensis. The effect of carbon source, nitrogen source, and mineral solution was studied. Lactose, yeast extract, and mineral solution were media components which showed significant effect toward production of P. lagena active compound. Composition optimization of these three medium components was done by response surface methodology (RSM). The Optimal response region of the significant factor was predicted by using a second order polynomial model with statistical design, central composite design (CCD). Higest production of P. lagena active compound by quadratic model was predicted to be 69.233% with medium composition 44.77 g L-1 lactose, 13.02 g L-1 yeast extract, and 15.95 mL L-1 mineral solution. Verification value in laboratory is 58.365%, lower 15.7% than its prediction. Optimization increase P. lagena active compound 9 fold compared to unoptimize media.

Summary Gamma linolenic acid (GLA) is a polyunsaturated fatty acid having high economic value as healthy oil. Research at laboratory scale showed that Absidia corymbifera and Rhizopus sp. fungi have the ability to increase unsaturation level of crude palm oil (CPO) and GLA formation through enzymatic bioconversion. Stability of desatu-rase enzyme, especially ∆6 and ∆12 having significant role in this process could be enhanced by applying immobilization technique. The current research objective was to determine optimum process of CPO bio-conversion using immobilized desaturase enzyme using continuous system at semipilot scale to produce CPO containing GLA. Crude desaturase enzyme of A. corymbifera biomass was immobilized with zeolite particles and used for optimization of CPO bioconversion in continuous system at semipilot scale (15,000 mL per day). Optimization of bio-conversion conditions included flow rate of substrate, size of zeolite for immobilization, and enzyme stability during process. The result showed that desaturase immobilized in small size particles of zeolite (1-3 mm) gave higher increase unsaturation level with average desaturase activity of 7.84 U, compared to that immobilized in larger zeolite particles (8-10 mm), which reached average desaturase activity of 4.67 U. However, the use of small zeolite particles often caused plugging substrate flow. The activity of immobilized desaturase in continuous system was stable for 9-18 hours. Optimum flow rate of substrate using small zeolite particles (1-3 mm) was 850 mL/min, while that of using larger zeolite particles (8-10 mm) was 875 mL/min. The bioconversion of CPO at optimum condition yielding 1.58% (w/w) GLA from initial concentration of linolenic acid 0.29%. RingkasanAsam γ-linolenat (GLA) merupakan asam lemak takjenuh majemuk yang memiliki nilai ekonomi tinggi sebagai minyak kesehatan. Penelitian pada skala laboratorium me-nunjukkan bahwa Absidia corymbifera dan Rhizopus sp. memiliki kemampuan untuk me-ningkatkan ketidak-jenuhan minyak sawit mentah (CPO) dan menghasilkan GLA melalui biokonversi enzimatis. Stabilitas enzim desaturase, khususnya ∆6 dan ∆12yang berperan pada proses ini dapat ditingkatkan antara lain melalui teknik amobilisasi. Penelitian lanjutan ini bertujuan menetapkan kondisi optimum biokonversi CPO untuk menghasilkan minyak yang kaya akan asam lemak takjenuh majemuk, khususnya GLA menggunakan enzim desaturase amobil sistem kontinu pada skala semipilot. Ekstrak kasar enzim desaturase asal biomassa fungi A. corymbifera diamobilisasi dengan butiran zeolit dan selanjutnya digunakan untuk optimasi proses biokonversi secara kontinu pada skala semipilot (15.000 mL per hari). Optimasi proses kontinu meliputi laju alir substrat, ukuran butiran zeolit, dan stabilitas enzim selama proses. Hasil penelitian menun-jukkan bahwa desaturase yang diamobilisasi pada zeolit berukuran kecil (1-3 mm) memberikan peningkatan ketidakjenuhan yang lebih tinggi dengan aktivitas rata-rata 7,84 U, dibandingkan dengan yang diamobilisasi pada zeolit berukuran besar (8-10 mm) dengan aktivitas rata-rata 4,67 U. Namun, penggunaan zeolit berukuran kecil sering menimbulkan sumbatan aliran substrat. Aktivitas desaturase amobil pada proses kontinu dapat bertahan selama 9-18 jam. Laju alir optimum substrat pada penggunaan zeolit berukuran kecil (1-3 mm) adalah 850 mL/menit, sedangkan pada penggunaan zeolit besar (8-10 mm) adalah 875 mL/menit. Biokonversi CPO pada kondisi optimum menghasilkan GLA 1,58% (b/b) dari kandungan asam linolenat awal 0,29%tration of linolenic acid 0.29%.

AbstractCultivation of Spirulina platensis in an abundant available and inexpensive medium such as palm oil mill effluent (POME) will produce biomass and valuable active materials at competitive price. Utilization of POME will also reduce pollution level and support cleaned production. The objectives of this research were to determine the dilution rate of S. platensis and the reduction rate of pollution level of POME on continuous photobioreactor. Preliminary research was conducted by growing S. platensis on POME medium with various concentration, namely 25%, 50%, 75%, and 90% POME on batch system. The experiment was conducted in 1.2 L capacity continous photobioreactor using medium containing a mixture of POME and synthetic medium. Feeding rate was set up at 0.05 mL/5 sec. (dilution rate of 0.03 hr -1), 0,05 mL/10 sec. (dilution rate of 0.015 hr -1), and 0.05 mL/15 sec. (dilution rate of 0.01 hr -1). For optimum dilution rate, the experiment was scaled up eight times using 10 L capacity continous photobioreactor. The results showed that optimum growth rate of S. platensis (µmax) = 0.233, was achieved using medium consisting of 90% POME and 10% synthetic medium after two weeks. Dilution rate of 0.015 hr -1 on photobioreactor was the optimum dilution rate for growth of S. platensis as well as for decreasing polution level of POME. The result of the eight-times scale up photobioreactor using flow rate of 0.4 mL/10 sec and dilution rate of 0.015 hr -1 showed that the growth of S. platensis was relatively constant as reflected by the OD value of the suspension culture and the concentration of cellular biomass. At the optimum condition, production of S. platensis biomass was 0.267g/L and pollution level was decrease 24%. The rate of outflow also resulted the constant decrease of polution level based on total carbon (TC), total dissolve solid (TDS), dissolve oxygen (DO), BOD, and COD parameters indicating that continuous photobioreactor was running at steady state.Abstrak Kultivasi S. platensis dalam media yang tersedia me-limpah dan murah seperti limbah cair pabrik kelapa sawit (LC-PKS) akan menghasilkan biomassa dan bahan aktif bernilai ekonomi tinggi dengan harga kompetitif. Pemanfaatan LC-PKS juga akan mengurangi dampak pen-cemaran lingkungan dan membantu menciptakan sistem produksi bersih. Penelitian ini bertujuan menetapkan laju dilusi optimum per-tumbuhan S. platensis dan laju penurunan tingkat cemaran LC-PKS pada fotobioreaktor sistem kontinyu. Untuk mengukur laju alir sistem kontinyu, pertama S. platensis ditumbuhkan pada media LC-PKS 25%, 50%, 75%, dan 90% dengan sistem batch. Pertum-buhan S. platensis pada fotobioreaktor sistem kontinyu kapasitas 1,2 L dirancang dengan variasi laju alir umpan berupa LC-PKS yang dicampur media sintetik pada konsentrasi optimum. Variasi laju alir pengumpanan diatur pada variasi 0.05 mL/5 detik (laju dilusi 0,03 jam-1), 0,05 mL /10 detik (laju dilusi 0,015 jam -1), dan 0,05 mL/15 detik (laju dilusi 0,01 jam-1). Pada laju alir optimum, skala percobaan diperbesar delapan kali menggunakan foto-bioreaktor berkapasitas 10 L. Hasil penelitian menunjukkan bahwa laju pertumbuhan maksimum (µ maks) adalah 0,233 jam-1 yang diperoleh dengan campuran media LC-PKS 90% dan media sintetik 10% selama dua minggu. Fotobioreaktor dengan laju dilusi 0,015 jam-1 merupakan laju alir umpan yang optimum untuk pertumbuhan S. platensis serta menghasilkan penurunan tingkat cemaran LC-PKS yang optimum. Hasil penelitian dengan perbesaran skala delapan kali menggunakan laju alir pengumpan 0,4 mL/10 detik (laju dilusi 0,015 jam-1) menunjukkan bahwa pertumbuhan S. platensis relatif konstan. Produksi biomassa sel rata-rata sebesar 0,267g/L dan kadar cemaran limbah rata-rata menurun sebesar 24%. Laju alir keluar (outflow) juga menghasilkan kadar cemaran limbah yang konstan ber-dasarkan parameter total karbon (TC), total dissolve solid (TDS), dissolve oxygen (DO), BOD, dan COD yang menunjukkan bahwa sistem fotobioreaktor kontinyu ini berjalan dengan baik.
