| Abstract | ||
| Abstract A solid state fermentation system consisting of 1:2 w/w wheat bran/fish scales was used for the production of gelatinase enzyme activity. The activity has been screened from a local isolate of Brevibacillus laterosporus at 37 ºC and using Tris-HCl buffer pH 7.5. Maximum activity obtained was 3.5 U/ml. Gelatinase protein content was precipitated using 60% ammonium sulfate. The enzyme has been partially purified on column chromatography technique using Sephadex G-150 column (1.5X30 cm). The elution was carried out using buffer phosphate pH 7.4. Three isoform peaks were recorded from degraded gelatin. The obtained purification fold and recovery were (10.58) and (43.42) % respectively. Results indicated the possibility of using purified gelatinase in industry fields. | ||
