Based on ethnopharmacological information, four different varieties of seeds were obtained from authentic seed suppliers. Ethanol, methanol, acetone, chloroform and petroleum ether seed extracts were assessed for antibacterial activity against wound isolates of Multi Drug Resistant -Methicillin Resistant Staphylococcus aureus (MDR-MRSA). Ethanol, methanol and acetone extracts of Moringa oleifera, Elettaria cardamomum and Tamarindus indica seeds showed more effective anti MRSA activity than Artocarpus heterophyllus. In addition Moringa oleifera seed extracts may have the potential to restore the effectiveness of -lactam antibiotics against MRSA.

Lipolytic enzymes from marine microbes have been the focus of intense and growing research. The bioluminescence bacterium Vibrio fischeri was produced lipase enzyme when the medium contained specific substrate. The lipase was purified from the concentrated culture supernatant. The most active fractions were obtained using the technique of precipitation with ammonium sulphate. The precipitated fraction was purified by desalting and ion exchange chromatography. The purified active fraction exhibiting final specific activity of 121U/mg and characterized; the optimum pH was likely between 7 to 8, the optimum temperature was 30°C and about 80 % of activity at 5°C. The enzyme was very stable at the pH 8, at the temperature 30°C. The enzyme was monomeric protein having molecular mass of 57 KDa estimated by native PAGE assay.

Lipolytic enzymes from marine microbes have been the focus of intense and growing research. The bioluminescence bacterium Vibrio fischeri was produced esterase enzyme when the medium contained specific substrate. The esterase was purified from the concentrated culture supernatant. The most active fractions were obtained using the technique of precipitation with 1N HCl. The precipitated fraction was purified by ion exchange chromatography (DEAE-Cellulose) and gel filteration chromatography (Sephadex G200). The purified active fraction exhibiting final specific activity of 300U/mg and characterized; the optimum pH was 7.5, the optimum temperature was 30°C. The enzyme was very stable at the temperature 30°C and at wide range of pH. The enzyme was monomeric protein having molecular mass of 37 KDa estimated by native PAGE assay.

CHROM agar Staphylococcus aureus and Oxacillin Resistant Screening Agar Base (ORSAB) media with oxacillin were evaluated for the screening of Methicillin Resistant Saphylococcus aureus (MRSA). Among 190 samples, totally 126 confirmed Staphylococcus aureus strains were used for screening of MRSA used CHROM agar and ORSAB media were compared with the other MRSA screening media like Baird Park agar (BPA) with ciprofloxacin, Mannitol salt agar (MSA) with oxacillin, Blood agar (BA) with oxacillin and Muller Hinton agar (MHA) with oxacillin. Totally 54 MRSA strains were confirmed using PCR, among that 83% and 92% of the MRSA stains were isolated as mauve colonies on CHROM agar and blue colonies on ORSAB medium in 24 hrs incubation, compare with 64%, 61%, 50%, and 42% of the strains that were isolated on BPA, MSA, BA and MHA respectively. After 48 hrs of incubation 100%, 98%, 77%, 77%, 72% and 68% of the MRSA strains were isolated on CHROM agar, ORSAB, BPA, MSA, BA and MHA respectively. CHROM agar Staphylococcus aureus and ORSAB agar proved to be more sensitivity and specificity than other MRSA selective media. These provide an alternative for the detection of MRSA in clinical laboratories, especially when PCR is unavailable.
