PURIFICATION AND BIOCHEMICAL CHARACTERIZATION OF AN EXTRACELLULAR LIPASE PRODUCED BY A NEW STRAIN OF Rhizopus sp
The present study had as a goal to purify and characterize the lipolytic fraction secreted by a strain of Rhizopus sp. Only 3 steps of purification were necessary to achieve SDS-PAGE homogeneity. One band with 37.5 KDa molecular mass and with 1446 U/ mg specific activity was obtained. The purified fraction presented 2 lipase isoforms; both showed optimum activity at 50oC, and were stable betwee...
متن کاملAntibacterial substance produced by Streptomyces sp . No . 87
An antimicrobial substance produced by Streptomyces sp. No. 87 was partially purified and studied for its antibacterial characteristics using the swab paper disc technique. The cell-free culture filtrate showed antibacterial activity against several species of pathogens including Gram-positive bacteria, i.e. Bacillus cereus ATCC 11778, B. subtilis TISTR 008, B. megaterium, Staphylococcus aureus...
متن کاملHAF, hepatoma aggregation factor produced by Streptomyces sp. strain No. A-6143.
We searched for a new cell aggregation factor for hepatoma AH109A cells, and found one we called HAF in the culture filtrate of Streptomyces sp. strain No. A-6143 isolated from a soil sample. HAF was purified by salting-out with ammonium sulfate. DEAE-cellulose column chromatography, gel filtration on Sephadex G-100, and hydroxylapatite column chromatography, HAF was glycoprotein which had a mo...
متن کاملA new antiherpetic agent produced by Streptomyces sp. strain no. 758.
A new antiherpetic agent, AH-758, was isolated from the culture broth of Streptomyces sp. strain No. 758. The structure was determined by NMR special analyses to be a new antibiotic belonging to bafilomycin group containing (5-oxo-2-pyrrolin-2-yl) methyl fumarate in its C-21.
متن کاملDeisovalerylblastmycin produced by Streptomyces SP.
A new antifungal antibiotic was isolated from the fermentation broth of Streptomyces sp. 5140-A1. Degradation studies of the crystalline antibiotic, m.p. 186 approximately 188 degrees C, C21H28O8N2, suggested Piricularia oryzae and less toxicity against killfish than antimycin A--blastmycin antibiotics.
