Discarded feathers represent an important residue from the poultry industry and are a rich source of keratin. Bacillus subtilis LFB-FIOCRUZ 1266, previously isolated from industrial poultry wastes, was used in this work and, through random mutation using ethyl methanesulfonate, ten strains were selected based on the size of their degradation halos. The feather degradation was increased to 115% and...
Forty-seven (47) mutant strains were generated from the wild-type fungus, Fusarium incarnatum strainLD-3 after exposure to ultraviolet radiation (UV) and a further seventeen (17) mutants were generated after exposure to ethyl methane sulfonate (EMS). Amongst these, the mutant strain, identified as UC-14, was the most promising laccase producer and produced threefold more laccase than the wild strain...
Extremophilic microbial derived lipases have been widely applied in different biotechnological processes due to their resistance to harsh conditions such as high salt concentration, elevated temperature, and extreme acidic or alkaline pH. The present study was designed to overproduce the halophilic, thermoalkalophilic lipase of Bacillus atrophaeus FSHM2 through chemically induced random mutagenesis...
