ABSTRACTHepatitis C virus (HCV) is the major causative agent of chronic liver disease. Recently, the inhibition of NS3 RNA helicase/ATPase activity is being explored as the specifically targeted antiviral therapy (STAT) against HCV infection. This study was aimed to elucidate potential candidates for anti-HCV therapy derived from Indonesian indigenous microalgae. The microalga designated as BTM 11 was isolated and cultured. Methanol extract of BTM 11 was screened as the opponent of purified HCV NS3 RNA helicase enzyme through colorimetric ATPase assay. Screening of chemical compound and fractionation by using gel filtration chromatography with eluent of methanol : chloroform (1:99) were conducted for identification and isolation of the bioactive compounds. The third fraction of fractionated sample showed a relatively strong ATPase inhibitory effect (81.23 Â± 2.25 %) compared to the negative control. Further analysis of third fraction using thin layer chromatography (TLC) with eluent of chloroform : methanol (9:2) gave two spots with the Rf value of 0.8 and 0.37, respectively. In addition, high performance liquid chromatography (HPLC) analysis showed absorption peak with the highest abundance at the retention time of 12.483 and 16.617 minutes which absorbed at 266 and 230 nm wavelenght, respectively. According to those analyses, this study suggests that bioactive compounds derived from BTM 11 were classified as the groups of flavonoids and feasible as potential candidates for anti-HCV therapy through the inhibitory effect of NS3 RNA helicase/ATPase activity.Â Keywords: Hepatitis C Virus, NS3 RNA helicase, ATPase, Microalga, FlavonoidsÂ

Sago solid waste as by product result of sago palm processing potentially have great value for some bio processing such as source of carbon on microbes substrate. Utilization of sago solid waste as substrate for filamentous cyanobacteria cultivation is a rareresearch activity in Indonesia as one of the three leading world companies producer of sago starch. Therefore, we focused on sago waste treatment using cyanobacteria agent in order to rid the waste and gain the value of nutrition rich starch from that waste. Several concentrations of growth media contain sago solid waste were tested into cyanobacteria culture and solid waste hydrolysis as pretreatment more conducted in the research. Result shows that addition of sago solid waste (50, 500 and 5000 ppm) into media can increase the algae biomass production which is rich of carbohydrate and protein.The proximate value of biomasses with sago solid waste treatment was exhibited significantly higher than control. During cultivation exposure time, the solid waste is gradually consumed by the algae. The study implies that sago solid waste can be used as substrate for the biomass production of filamentous cyanobacteria which is known as source of active compounds, potential resource for valuable bioproduct.

Pseudomonas has the potential ability for production of citrate synthase synthesis. Pseudomonas aeruginosa could synthesize the enzyme of citrate synthase which is most likely compatible with microalgae cell. Pseudomonas aerugenosa can be found in the rhizosphere of Kruing (Dipterocarpus sp., Dipterocarpaceae). This bacteria is commonly used in agriculture purposes because it is able to synthesize organic acid such as citric acid. These organic acids are synthesized from a reaction between oxaloacetate and acetyl CoA, catalyzed by citrate synthase (CS) in the tricarboxylic acid cycle (TCA). Rhizosphere as microbial sources was obtained from Kruing (Dipterocarpus sp.), which was collected from ?Carita? Research Forest, Pandeglang, Banten, West Java. Citrate synthase gene-specific primers were designed based on citrate synthase gene sequences as depicted in Genbank. The isolation and amplification showed that citrate synthase can be detected and purified from Pseudomonas aeruginosa target and it consists of 1600 bp and encodes 509 amino acids. Based on BLAST (Basic Local Alignment Search Tool) analysis, CS genes that were successfully isolated had 92 % similarity with Pseudomonas aeruginosa type II citrate synthase. This CS gene is expected to be expressed in microalgae metabolism to divert the metabolism of carbohydrate formation into fatty acids.
