Cloning, characterization and functional analysis of lichenase produced by Bacillus licheniformis RB16 isolated from cattle faeces.

Lichenan, 1,3-1,4-β-Glucan, a linear polysaccharide exists in the cell walls of various cereals, has garnered attention for its industrial applications due to its enzymatic breakdown by lichenase enzymes. In this study, Bacillus licheniformis strain RB16, isolated from cattle faeces, was identified as a robust lichenase producer. The lichenase gene, licA, was successfully cloned and characterized.

Uterine microbial ecology and disease in cattle: A review.

Due to the critical contribution of the uterine-associated microbiota in reproductive health, physiology, and performance, culture-independent methods have been increasingly employed to unravel key aspects of microbial ecology in the uterus of cattle. Nowadays, we know that bacterial diversity is crucial to maintain uterine health, however, there is still no consensus on the exact composition of a healthy uterine microbiota (or eubiosis). Generally, loss of bacterial diversity (or dysbiosis) contributes to the development of uterine infections, associated with increased relative abundances of Bacteroides, Fusobacterium, Trueperella, and Porphyromonas.
