Abstract

Ethanol is considered as the most promising alternative fuel, since it can be produced from a variety of agriculturally-based renewable materials, such as sugarcane bagasse. Lignocellulose as a major component of sugarcane bagasse is considered as an attractive renewable resource for ethanol production due to its great availability and relatively low cost. The major problem of lignocellulose is caused by its need for treatment to be hydrolyzed to simple sugar before being used for bioethanol production. However, pretreatment using acid as hydrolyzing agent creates some inhibitor compounds that reduce ethanol production because these compounds are potential fermentation inhibitors and affect the growth rate of the yeast. Reduction of these by-products requires a conditioning (detoxification and culture starter adaptation). Thus, the aim of this study was to evaluate bioethanol production by fermentation with and without detoxified sugarcane bagasse acid hydrolysate using adapted and non-adapted culture of C. tropicalis. According to this study, the highest ethanol amount was obtained about 0.43 % (v/v) with an ethanol yield of 2.51 % and theoretical yield of 4.92 % by fermentation of sugarcane bagasse hydrolysate with detoxification using the adapted strain of C. tropicalis at 72 hours fermentation time. Furthermore, the addition of 3 % glucose as co-substrate on detoxified-hydrolysate media only achieved the highest ethanol concentration 0.21 % after 24 hours fermentation with the ethanol yield 0.69 % and theoretical ethanol yield 1.35 %, thus it can be concluded that the addition of glucose could not increase the ethanol production.

Abstract

High cost production is one of the constraints of the commercial xylitol production due to high energy needed and pure raw materials. Therefore, it is necessary to improve the xylitol production eficiently with lower production cost by using microorganisms. The research objectives were to determine the optimum xylitol production from xylose by metabolism of C. guilliermondii and effect of glucose as a co-substrate in fermentation medium. The ratio of glucose : xylose (g/L) was 1:25, 1:12, 1:5 and 1:2.5 respectively. The xylitol concentration was measured by spectrophotometer method (D-sorbytol/D-xylitol kit). The result showed that the exponential phase of Candida guilliermondii was 12 h to 36 of incubation and optimum of incubation time to produce the highest xylitol was 72 h. The best ratio- of glucose : xylose to produce xylitol was 9 g/L glucose : 45 g/L xylose (1 : 5). The xylitol concentration produced from medium with the addition of glucose was 2.85 g/L. This concentration increased five times compared to that in the medium without addition of glucose that only reached 2.85 g/L. According to this study, the addition of glucose as a co-substrate could increase the xylitol production.

Abstract

Temulawak or Curcuma xanthorrhiza Roxb, is usually used as traditional medicine (herbal medicine) that has antioxidant, anticancer, antihyperglycemic, anti-inflammatory, hepatoprotective and gastroprotective properties. The main components contained in temulawak responsible for its efficacy as a medicine are xantorhizol and curcuminoid. Curcuminoid has drawbacks, which are difficult to absorb and very quickly metabolized by the body, so that limit its bioavailability. The use of solid lipid nanoparticle carrier system (SLN) in form of palmitic acid, is known to improve the bioavailability of curcuminoid. This study aims to find the effective dose of nanocurcuminoid coated with palmitic acid that can be used as an anti-inflammatory agent. The methods used in this study, include the production of nanocurcuminoid with homogenization and ultrasonication methods, determination of particle size, polydispersity index, entrapment efficiency and anti-inflammatory activity test through rat feet edema. Nanocurcuminoid obtained in this study was 561.53 nm in size, with polydispersity index 0.309 and concentrations of curcuminoid absorbed and entrapment efficiency were 0.61±0.031 mg/mL, 58.93±3.021%, respectively. Anti-inflammatory activity of nanocurcuminoid through treated Sprague Dawley rats, showed that there were no significant difference compared with the positive control, curcuminoid extracts and empty nanoparticle. These results indicate that nanocurcuminoid with 175, 200 and 250 mg/kg.bw in doses, has greater anti-inflammatory activity (31.70%) compared to the other treatments.

Abstract

Breast cancer is one of the most common cancer in the world that occurs in women. Thedevelopment process of cancer is regulated by a variety of pathways that involve various enzymes. COX-2 is an enzyme involved in the inflammatory process in further stages that will play importantroles in breast cancer cells progression. The uses of natural compound from plants give new hope forbreast cancer treatment with minimal side effects. Temulawak is a potential breast cancer drugs because it contains curcuminoid and xanthorizol. Curcumin and xanthorizol has been reported to have chemopreventive effect on colon cancer development. The drug that has same functions of these compounds needed to be examined with various approaches. One of the approach used in this research is molecular docking. Based on ligand analysis with Lipinski and toxicity test using ADMET, curcuminoid and xanthorizol met criteria as medicinal compounds. Curcumin had the highest binding affinity(?G) with the value -9.3 kcal/mol but still under commercial drug celecoxib binding affinity (?G) = -12,5. There were three hydrogen bonds in amino acid Arg106 and Tyr341 His75 which were amino acids in the active side of COX-2. There were 15 amino acids that have similar ties with commercial drug celecoxib. Based on the binding affinity and binding similiarity, curcuminoid and xanthorizol were predicted as compounds that have potential as competitive inhibitor of COX-2 enzyme.

Abstract

Curcuminoid, a natural compound isolated from Curcuma xanthorrhiza RoxB (Temulawak) has been reported to possess antioxidant, anti-inflammatory, anticancer, antimicrobial and anti-hyperglicemic properties. The curcuminoid is weakly soluble in water that restricts its bioavailability. This problem could be overcome by incorporating curcuminoid into solid lipid nanoparticles (SLN). Nanocurcuminoid was prepare by using homogenization-ultra sonication methods. Nanocurcuminoid obtained in this study was 523.5 nm in size and polydispersity index of 0.218 with entrapment efficiency of 24.2 %. Rats were made diabetic by induction of 50 mg / kg BW STZ, treated with the chosen formula (doses 5, 10, 20 mg/kg BW) orally for 15 days. Body weight and blood glucose levels were measured from day 0, 4th,7th,11th and 15th. The results showed that 15 days of daily treatment of 10 mg/kg BW nanocurcuminoid emulsion led to a reduction of blood glucose level by 30.93±14.90 % and body weight by 15.5±13.92 %. Curcuminoid formulated in solid lipid nanoparticles could suppress a decrease in body weight and lower blood glucose levels of rats.

Abstract

Trichodermin has antifungal activity against Ganoderma boninense, but it is volatile and insoluble in water. Research on trichodermin as antifungal G.boninense has been done, but not yet at the stage of altering the nature of the compound. This study aims to develop trichodermin as antifungal G. boninense in the form of nanoenkapsulat with observed aspects including formulation, encapsulation, characterization, and antifungal activity. Trichodermin is extracted from Trichoderma harzianum by maceration. Nanoemulsion is made using Emulsion Inversion Point (EIP) method and encapsulation is done by spray drying. Antifungal activity was tested using a modified dual culture assay method. The results showed the rendement of trichodermin extraction of 0.70%. The best nanoemulsion formula is nanoemulsion with Tween 80 concentrations of 75% of the total organic phase. The formula nanoemulsi has a size of 231.95 nm, polydispersity index of 0.348, and zeta potential of -35.6 mV. Encapsulation has a yield of 5.79%. The encapsulated powder has a moisture content of 5.79%, contains a typical functional group of trichodermin compounds, and is round with an uneven surface. The antioxidant activity of nano-trichodermin encapsulation is higher than trichoderminextract and positive control (hexaconazole) with PIRG value of 84.40%.
