Exploring the hemicellulolytic properties and safety of Bacillus paralicheniformis as stepping stone in the use of new fibrolytic beneficial microbes.

Bacillus strains from the Moroccan Coordinated Collections of Microorganisms (CCMM) were characterised and tested for fibrolytic function and safety properties that would be beneficial for maintaining intestinal homeostasis, and recommend beneficial microbes in the field of health promotion research. Forty strains were investigated for their fibrolytic activities towards complex purified polysaccharides and natural fibres representative of dietary fibres (DFs) entering the colon for digestion. We demonstrated hemicellulolytic activities for nine strains of Bacillus aerius, re-identified as Bacillus paralicheniformis and Bacillus licheniformis, using xylan, xyloglucan or lichenan as purified polysaccharides, and orange, apple and carrot natural fibres, with strain- and substrate-dependent production of glycoside hydrolases (GHs).

Draft genome sequence of a mosquito repellent strain Ba1 isolated from desert soil.

Microbial volatile organic compounds have been shown to affect a wide insect behavior. In this paper, we report the draft genome sequence of strain Ba1 previously isolated from desert soil in Morocco. The assembled and annotated draft genome contains 4,726 coding genes, 6 rRNAs and 97 tRNAs.

Hemicellulosic biomass conversion by Moroccan hot spring CCMM B940 evidenced by glycoside hydrolase activities and whole genome sequencing.

Unlabelled: Thermophilic bacteria, especially from the genus , constitute a huge potential source of novel enzymes that could be relevant for biotechnological applications. In this work, we described the cellulose and hemicellulose-related enzymatic activities of the hot spring CCMM B940 from the Moroccan Coordinated Collections of Microorganisms (CCMM), and revealed its potential for hemicellulosic biomass utilization. Indeed, B940 was able to degrade complex polysaccharides such as xylan and lichenan and exhibited activity towards carboxymethylcellulose.
