Surveillance studies have shown that feeding pigs liquid diets and particularly fermented liquid diets reduces the incidence of Salmonella positive herds. Studies have shown that a concentration of 70 mmol kg lactic acid is bacteriostatic to Salmonella and that concentrations >100 mmol kg are bactericidal. Uncontrolled natural fermentation results in lactic acid concentrations varying between 0...

Oenococcus oeni is an acidophilic member of the Leuconostoc branch of lactic acid bacteria indigenous to wine and similar environments. O. oeni is commonly responsible for the malolactic fermentation in wine and due to its positive contribution is frequently used as a starter culture to promote malolactic fermentation. In collaboration with the Lactic Acid Bacteria Genome Consortium the genome ...

Gluconic acid reaches the large intestine to stimulate lactic acid bacteria. However, the fermentation pattern of gluconic acid has yet to be elucidated. Accordingly, we examined the fermentation properties induced by gluconic acid in the pig cecal digesta in vitro. We also tested sorbitol and glucose, substrates for which the fermentation rate and patterns are known. The gluconic acid–utilizin...

The recent discovery of the bio-waste and excreta treatment of a former civilisation in the Amazon reveals the possibility of a highly efficient and simple sanitation system. With the end product that was black soil they converted 10% of former infertile soil of the region: Terra Preta do Indio (black soil of the Indians). These soils are still very fertile 500 years after this civilisation had...

The present study applied the PacBio single molecule, real-time sequencing technology (SMRT) in evaluating the quality of silage production. Specifically, we produced four types of Medicago sativa silages by using four different lactic acid bacteria-based additives (AD-I, AD-II, AD-III and AD-IV). We monitored the changes in pH, organic acids (including butyric acid, the ratio of acetic acid/la...

Ozonation of uncooked corn mash from the POET BPX process was investigated as a potential disinfection method for reducing bacterial contamination prior to ethanol fermentation. Corn mash (200 g) was prepared from POET ground corn and POET corn slurry and was ozonated in 250 mL polypropylene bottles. Lactic and acetic acid levels were monitored daily during the fermentation of ozonated, aerated...

The present study evaluated functional properties of lactic-fermented ginger products. Three Zingiberaceae species were used as the substrate for fermentation using three lactic acid bacteria. The fermentation process ended 35-40 h after inoculation and reached a pH value of 3.5-4.0. Total antioxidant performances were 68-75%, and were best observed using Bifidobacterium longum as the starter i...
