简介
The present study was conducted with an objective to isolate and screen bacteria with dual characteristics of cellulase and keratinase production from soil of feather dumping site and from the gut of cockroaches which inhabit these sites. By using standard microbiological protocols and techniques, 13 bacteria (K1–K13) were isolated from soil samples and 18 isolates from cockroach gut (K14–K31), and further these isolates were screened for keratinase activity. The positive isolates with keratinase activity were subsequently screened for cellulase production. The enzymatic activity of both keratinase and cellulase was quantified followed by characterization and identification of these positive isolates through 16S rRNA genetic region sequencing. The isolate showing maximum keratinase and cellulase enzyme activity was selected and tested for degradation potential using animal skin with hairs as a natural …
