Abstract

The research of screening and isolation of cellulase-producing bacteria from bagasse had been done. The objectives of the research were to obtain cellulolytic bacteria isolate, to determine the genus of the isolates and also to characterize the crude enzymes produced. One isolate with the highest activity was chosen to be purified further bystreak plate and pour plate methods in carboxyl methyl cellulose(CMC)  agar media. The genus of the pure isolated bacteria was further characterized by macroscopic and microscopic properties, and biochemical assays using conventional methods and MicrobactTM Kit: gram-negative identification system (Oxoid). The result showed that the isolated cellulolytic bacteria had a close character similarity to Bacillus pumilus. The isolate was grown on MHB + CMC media with 2 hours of adaptation phase followed by logarithmic phase until 21 hours of incubation. Cellulase was started to be produced after 4 hours of fermentation and reached the highest activity at 21 hours of fermentation. The cellulase produced had the pH optimum at pH 5 and a temperature optimum at 60 °C, with optimum activity ranging from 0.0231 to 0.0264 U /ml. One unit of cellulase activity is defined as the amount of enzyme that will catalyze the production of 1 mg of glucose per minute at 37°C and pH 7.0. Keywords:  bagasse, bacteria isolation, cellulolytic, biochemical characterization, enzyme characterization

Abstract

Cinnamic acid is one of known tyrosinase inhibitors. This study investigated the inhibition of tyrosinase activity of some cinnamic acid derivatives, i.e. 4-buthoxy-cinnamic acid, 4-n-butylcinnamic acid and 4-phenylcinnamic acid. Each inhibitor used in this research had the same type of inhibition towards enzymatic activity, i.e. mixed type inhibition of competitive and non competitive type. The potential sequence of tyrosinase inhibition based on the ratio of its IC50 compared to cinnamic acid, from the lowest to the highest were 4-buthoxycinnamic acid, 4-phenylcinnamic acid and 4-n-butylcinnamic acid. Based on the obtained results of this research, it was disclosed that n-butyl substituent on para position did not increase the inhibition effect of cinnamic acid towards tyrosinase enzymatic reaction. But in the other hand, buthoxy and phenyl substituent on para position could increase the inhibition effect of cinnamic acid towards tyrosinase enzymatic reaction because buthoxy substituent increased the similarity of its structure with the substrate of enzymatic reaction while phenyl susbtituent blocked the substrate-enzyme reaction.

Abstract

Jamu/Herbal Medicine that contain chemical compounds/Pharmaceutical compounds has been banned by The National Agency of Drug and Food Control in Indonesia, but in December 2017, BPOM released a public warning about aphrodisiac herbal medicine that contain chemical compound like sildenafil citrate and phenylbutazone in the market. The aim of this study was to find out the valid method for identification of sildenafil citrate and phenylbutazone in aphrodisiac herbal medicine. In this study, the developed method was applied to 22 brands of aphrodisiac herbal medicine sample. Sample was extracted with methanol, then 5 µl of sample spotted on silica gel plate 60 F 254 and eluated by chloroform : methanol : amonia (70 : 3 : 1.5, v/v/v). The spots were analyzed by TLC scanner at λ 286 nm. Sildenafil citrate was appeared at Rf 0.76; tadalafil at 0.6 and phenylbutazone at Rf 0.12 with resolution (Rs) value of sildenafil and tadalafil was 1.1 meanwhile tadalafil and phenylbutazone was 5.4. Limit of detection of sildenafil citrate was 8.552 µg/ml (2.053 mg/600 mg capsul), tadalafil was 1.629 µg/ml (0.391 mg/600 mg capsul), and phenylbutazone was 7.877 µg/ml (1.890 mg/600 mg capsul). This study found 14 brands that gave a positive result containing sildenafil citrate and no sample contain tadalafil and phenylbutazone.
