Abstract

•Potential probiotic attributes of B. amyloliquefaciens AMS1 isolated from traditional fermented soybean.•Cellulolytic activity on maize straw was shown by B. amyloliquefaciens AMS1.•It could be used as animal feed additives for better digestibility of the feed and enhanced productivity of the animal.•The optimum conditions for cellulase production were 37 °C and pH 5.5–6.5.

A microorganism showing probiotic attributes and hydrolyzing carboxymethylcellulose was isolated from traditional fermented soybean (Churpi) and identified as Bacillus amyloliquefaciens by analysis of 16S rRNA gene sequence and named as B. amyloliquefaciens AMS1. The potentiality of this isolate as probiotic was investigated in vitro and it showed gastrointestinal transit tolerance, cell surface hydrophobicity, cell aggregation and antimicrobial activity. The isolate was found to be non-hemolytic which further strengthens its candidature as a potential probiotic. The maize straw digestion was confirmed by scanning electron microscopy studies. The isolate was able to degrade filter paper within 96 hours of incubation. This study explores the possibility of combining the cellulase degrading ability of a microbe with its probiotic attributes to enhance gut health of animal and digestibility of the feed.
