Activity-based approach for microbial biocatalysts
Screening of microbes for enzymes involves one or more of the following approaches: (i) screening specific ecological niches, where desired activity is likely to be found; (ii) screening composite materials (e.g. soil samples) for organisms with specific activities under specific conditions of pH, temperature, etc.; and (iii) screening previously identified organisms, known to be good enzyme producers.

Most commercialized microbial enzymes come from a. small number of (i) fungi (e.g. Aspergillus, Fusarium, Trichoderma and Humicola belonging to Ascomycetes; Mucor, Rhizomucor belonging to zygomycetes, and (ii) bacteria (e.g. Bacillus, Pseudomonas). The enzymes cellulase, lipase and xylanases are particularly produced by Humicola spp, while rennilase and lipases ate produced by Mucor and Rhizomucor.
