ABSTRACT
A strain of Penicillium chrysogenum was isolated from Tedania anhelans (marine sponge) collected from Indian Ocean (8°22'30â³N latitude and 76°59'16â³ longitude) and deposited in culture collection centers. The strain subjected to different culture conditions for production of extrolites were extracted using ethyl acetate and chloroform. When both extracts were subjected for antibacterial activity, latter had high activity. Minimum inhibitory concentration of chloroform extract ranged from 31.25-1000 µg/mL in tested microbes such as, Mycobacterium tuberculosis H37Ra, Mycobacterium avium, Mycobacterium fortuitum, Mycobacterium smegmatis, Mycobacterium vaccae, Staphylococcus aureus, Aeromonas hydrophila, Pseudomonas aeruginosa and Vibrio cholerae. No cytotoxicity was observed in Vero cell line up to 399.10 µg/mL. Antibacterial activity previously reported by Parameswaran et al. in 1997 from ethyl acetate extract of T. anhelans might be due to the diketopiperazines, Cyclo-(L-Pro-L-Phe) and Cyclo-(L-Leu-L-Pro) produced by the associated fungi-P. chrysogenum DSOA. It is producing a metabolites having antimycobacterial activity, a first report.
