Bovicin is a type AII lantibiotic, possessing two β-methyllanthionine and a disulfide bridge encoded by bovA gene hitherto unknown a couple of decades ago. Bacteriocins can be useful in directly inhibiting methanogens and/or redirecting H2 to other reductive microorganisms, in particular, propionate producers or reductive acetogens. So far, the role of nisin and bovicin to suppress greenhouse gas (GHG) production under in vitro conditions has been documented. GHG emissions from ruminants are a threat to the environment, because of their role in global warming as well as in climate change...

Antimicrobial peptides (AMPs) are compounds widely distributed in nature that display activity against a broad spectrum of pathogens. Amphibian skin, as an organ rich in pharmacologically active peptides, appears to be an interesting source of novel AMPs. Aurein 1.2 (GLFDIIKKIAESF-NH2 ) is a short 13-residue antimicrobial peptide primarily isolated from the skin secretions of Australian bell frogs. In this study, the alanine scan of aurein 1.2 was performed to investigate the effect of each amino acid residue on its biological and physico-chemical properties...

Hylak® forte is a postbiotic that inhibits the growth of pathogenic bacteria by reducing intestinal pH. It is assumed the potential presence of short-chain fatty acids (SCFAs) in Hylak® forte may contribute to this effect. In this current study, we analysed the composition of Hylak® forte, using a validated gas chromatography assay test method, to ascertain whether SCFAs are present in this postbiotic treatment. Hylak® forte was screened for C1 to C10 SCFAs by a gas chromatographic assay. In this assay, SCFAs were analysed as for their volatile ethyl ester derivatives in a 3...
