Abstract

Spirulina is a microalgae that has been widely used as various supplements and medicines because of its high nutritional content. The need for new antibacterial sources to solve the problem of antibiotic resistance, makes the potential of Spirulina as an antibacterial agent necessary to be researched. This study aims to analyze the antibacterial activity of ethanol extract of Spirulina platensis obtained from the Indonesian region against Staphylococcus aureus and Escherichia coli. Spirulina samples were macerated in ethanol solvent in a ratio of 1:10 (w / v). The antibacterial test used was the disc diffusion method with clindamycin positive control. Antibacterial test results showed that S. platensis in this study did not have antibacterial activity against E. coli and S. aureus.

Abstract

In this study, cellulase was produced by endophytic fungus isolated from seagrass. Substrate used for incubating the fungus was the waste of agar industry. The objectives of this study were to optimize cellulase production and to characterize the highest activity of fungal crude cellulase. In our previous study, the EN isolate (isolated from Enhalus sp.) showed the highest cellulolytic index. Therefore, in this research we focused on cellulase activity of the isolate. Cellulase activity was determined based on endoglucanase activity, total cellulase activity, and β-glucosidase activity. The highest activity was then used to determine cellulase activity in enzyme characterization. The fungus was cultured in different concentration of agar extraction algal wastes. The fungal culture was incubated for 3-21 days with 120 rpm orbital shaker. The results showed that endoglucanase activity was 0.019-0.031 U/mL, total cellulase activity was 0.007-0.013 U/mL, and β-glucosidase activity was 0.00012-0.00361 U/mL. The highest endoglucanase and total cellulase activity were obtained from the fungal culture after 9 days incubation, β-glucosidase was obtained from the fungal culture after 15 days incubation with 1.5% of algal waste as substrate. The optimum pH and temperature were determined as 4 and 60 oC, maximum reaction rate (Vmax) and Michaelis-Menten constant (Km) for endoglucanase activity was determined as 0.044 U/mL and 0.103% respectively. Keywords: algal waste, cellulase, endophytes, enzymes, seagrass

Abstract

Cellulolytic fungi are potentially useful in biotechnology. Decomposition of substrates containing cellulose can be applied in bioethanol and enzymes production. Fungi are one group of microorganisms that can decompose cellulase materials.  This study aimed to obtain potential cellulolytic fungi isolated from marine habitat. Screening of the fungi was performed using CBM media with different salinity. Six isolates were tested quantitatively for cellulolytic activity using congo red staining. Cellulolytic index of algicolous and manglicolous fungi were lower than those of EN isolate, Veronea sp. KT19, and sponge associate (SMH). Fungi cultured in freshwater and seawater media possessed higher cellulolytic index in compared to those of cultures in 3% NaCl medium. However, freshwater and seawater media showed no significant effect. Cellulolytic index of EN isolate, Veronaea sp. KT19, and SMH after six days of incubation were 1.357; 1.267, and 1.278, respectively. All six isolates potentially produced cellulase in all medium tested.

Abstract

This study aimed to determine the best dose of administration of marine fungal Nodulisporium sp. KT29 metabolites to improve the production performance of marine culture of white shrimp. The experimental animals used were white shrimp Litopenaeus vannamei post larvae 12, which were reared in the sea using floating net cages with a stocking density of 700 post larvae/net. Experimental design used was a completely randomized design consisting of 3 treatments with 3 replications; control without the administration of Nodulisporium sp. KT29 metabolites, dietary of feed containing Nodulisporium sp. KT29 metabolites at doses of 20 mL/kg of feed and 40 mL/kg of feed. The results showed that survival rate, absolute length growth, weight gain, daily growth rate and feed conversion ratio in treatment groups were better than the control (P<0.05). The administration of marine fungal Nodulisporium sp. KT29 metabolites at a dose of 20 mL/kg of feed could improve the production performance of white shrimp cultivated in the sea with survival rate, daily growth rate and feed conversion ratio: 66.61±6.94%, 20.18±0.39 %/day and 3.20±0.22, respectively.

Abstract

Caulerpa racemosa merupakan rumput laut hijau yang mengandung senyawa aktif yang berpotensi sebagai antibakteri dan antioksidan. Perbedaan profil fitokimia dan bioaktivitas suatu ekstrak dapat dipengaruhi oleh kepolaran pelarut ekstraksi. Penelitian ini bertujuan untuk mempelajari profil fitokimia, aktivitas antibakteri, dan antioksidan ekstrak C. racemosa. Ekstrak diperoleh dari sampel segar C. racemosa yang dimaserasi menggunakan pelarut n-heksana, etil asetat, dan metanol. Uji antibakteri dilakukan dengan metode Resazurin Microtitter Assay (REMA) terhadap bakteri Escherichia coli dan Staphylococcus aureus. Aktivitas antioksidan diuji menggunakan metode 1,1-diphenyl-2-picrylhydrazyl (DPPH) dan Ferric Reducing Antioxidant Power (FRAP). Hasil penapisan fitokimia memperlihatkan bahwa ekstrak n-heksana mengandung alkaloid dan triterpenoid, sedangkan ekstrak etil asetat dan metanol mengandung alkaloid, flavonoid, tanin, fenol, dan steroid. Aktivitas antibakteri terbaik ditunjukkan oleh ekstrak etil asetat dengan nilai Minimum Inhibitory Concentration (MIC) terhadap E. coli sebesar 250 mg/mL. Ekstrak etil asetat C. racemosa juga memperlihatkan aktivitas antioksidan terbaik dengan nilai IC50 DPPH sebesar 110,7 mg/mL dan nilai FRAP sebesar 96,68 mmol Fe (II)/g. ABSTRACTCaulerpa racemosa is a green seaweed that contains active compounds that are potential for antibacterial and antioxidant.

Abstract

Mangrove plants are known as source of traditional medicines. Endophytic fungi have an important economic potential for antibacterial, enzyme and secondary metabolites that are useful especially in pharmaceutical industry. The purpose of this research was to determine the antibacterial activity of the endophytic fungal extracts from mangrove plant Rhizophora mucronata against diarrhea causing bacteria. This research included isolation, characterization, cultivation, extraction, and antibacterial activity test. The study yielded 5 types of endophytic fungi with different morphology. Endophytic fungus DS1 was the selected isolate based on antagonism test. The growth pattern showed the stationary phase of isolate DS1 was on the 15th day. Culture broth extract showed considerable inhibition on Pseudomonas aeruginosa with diameter of inhibition zone was 18.5 mm ± 3.32. Extract of mycelium inhibited the growth of Staphylococcus aureus (2 mm). The culture broth extract showed more potent antibacterial activity in comparison with the mycelium extract.

Abstract

Fatty acids and carotenoid has been known as an anticancer agent on both preventing and treating cancer disease. This study was conducted to analyze the fatty acid profile, carotenoid and in vitro anticancer activity of 12 sea cucumber harvested from Karimunjawa and Lampung waters. The aim of the study was to determin the potency of sea cucumbers as raw material for nutraceutical products. Fatty acid profile and carotenoid content were characterized by gas chromatography and spectrophotometry techniques, while in vitro anticancer activity was assessed by MTT assay against cervix (HeLa), breast (T47D and MCF-7) and colon (WiDR) cancer cells. Results of the study showed polyunsaturated fatty acid (PUFA) dominated the composition of fatty acids in the samples from both locations. Holothuria sp. was detected to contain the highest amount of carotenoid. Furthermore, the highest in vitro anticancer activity was detected also in the sample of Holothuria sp. The activity of 30 ppm Holothuria sp. extract against HeLa cell was detected to be almost equal to the 5 ppm doxorubicin control. Concentration of 5 ppm Holothuria sp. extract also showed positive result in killing 50% of MCF-7 and T47D, but capable to 100% kill HeLa and WiDR cells. At concentration of 25 ppm, the extract was able to kill all the 4 cells tested. Statistical analysis showed the amount of carotenoid and two particular fatty acid compounds (docosadienoic and eicosapentaenoic acid) significantly (P0.05) contributed to the cytotoxic activity that was found in the sea cucumber samples. Those compounds were found in highest concentration from Holothuria sp harvested from Lampung waters, thus being the most prospective raw material for nutraceutical or functional food ingredient with anticancer potency.
