PURIFICATION AND PARTIAL CHARACTERISATION OF AN ANTIFUNGAL BACTERIOCIN FROM Bacillus sp. Sh10 ASSOCIATED WITH MARINE CARPET CLAM (Paphia textile)
This study was conducted to purify and characterize an anti- C. albicans bacteriocin produced by Bacillus sp. Sh10 isolated from marine carpet clam, Paphia textile. Extracellularly produced bacteriocin was purified by 80 % ammonium sulfate precipitation and size exclusive gel chromatography using superdex-200 column chromatographyThe purification steps resulted in 3.68-fold increase in specific activity and recovery of 20.66 % of total activity. The purity rate and molecular mass of 11 KDa of this compound were determined using sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE). Profile analysis of this bacteriocin by electrospray mass spectrometry (LC/MS/MS) showed 43% protein sequence coverage with a putative uncharacterized protein from Bacillus cereus strain B4264.
