Abstract Background Penicillium funiculosum NCIM1228 is a non-model filamentous fungus that produces high-quality secretome for lignocellulosic biomass saccharification. Despite having desirable traits to be an industrial workhorse, P. has been underestimated due lack of reliable genetic engineering tools. Tolerance towards common fungal antibiotics had one the major hindrances development transformation tools against fungi. In this study, we sought understand mechanism drug tolerance and...

Bacillus amyloliquefaciens PFB-01 produced extracellular alkaline protease (385.25 U/ml) under shake flask conditions. Effects of process parameters such as cultivation period, pH, temperature, carbon and nitrogen sources on production were investigated for optimization. Production was optimized with 5.0% inoculum size in culture medium (pH 8.0) incubated 48 h at 37°C 200 rpm.
