#1
R Mezencev, C Klement
Human foodborne botulism is an intoxication caused by ingestion of botulinum neurotoxins (BoNT) of serotypes A, B, E, and rarely also serotype F, produced in contaminated food by anaerobic bacteria Clostridium botulinum group I, group II, or by toxigenic strains of C. butyricum and C. baratii. BoNT-producing Clostridia are ubiquitously distributed in the environment and, under suitable conditions, they can enter the food chain, proliferate and produce BoNT in a variety of foods. In the past, the risk of foodborne botulism was primarily associated with homemade canned foods; however, the epidemiological importance of commercial and restaurant food is increasing nowadays...

The antagonistic activity against gastrointestinal bacterial pathogens is an important property of probiotic bacteria and a desirable feature for pre-selection of novel strains with probiotic potential. Pre-screening of candidate probiotics for antibacterial activity should be based on in vitro and in vivo tests. This study investigated whether the protective activity of probiotic bacteria against gastrointestinal bacterial pathogens can be evaluated using Galleria mellonella larvae as an in vivo model. Larvae were pre-inoculated with either of two widely used probiotic bacteria, Lactobacillus rhamnosus GG or Clostridium butyricum Miyairi 588, and then challenged with Salmonella enterica Typhimurium, enteropathogenic Escherichia coli or Listeria monocytogenes...

Calcium carbonate was evaluated as a replacement for the base during the fermentation of glycerol by a highly productive strain of 1,3-propanediol (PDO), viz., Clostridium butyricum JKT37. Due to its high specific growth rate (µmax=0.53h(-1)), 40g/L of glycerol was completely converted into 19.6g/L of PDO in merely 7h of batch fermentation, leaving only acetate and butyrate as the by-products. The accumulation of these volatile fatty acids was circumvented with the addition of calcium carbonate as the pH neutraliser before the fermentation was inoculated...

The causes of periodontal disease are complex. Butyric acid, a metabolite of periodontopathic bacteria such as Porphyromonas gingivalis, acts as a histone deacetylase inhibitor that has a direct effect on mRNA expression. Butyric acid produced by Clostridium butyricum in the intestinal tract induces differentiation of regulatory T cells, thereby suppressing inflammation in the gut. Mice lacking Clostridium butyricum in the intestinal tract suffer from colitis. By contrast, butyric acid in the oral cavity worsens periodontal disease...
