Screening of different adjuvants, namely, suspending agents, phagostimulants, stickers, antimicrobial agents, and UV screens to develop aqueous biopesticidal suspensions of Bacillus thuringiensis (Bt) variety kurstaki HD-1 fermented broths, specifically, nonhydrolyzed sludge, hydrolyzed sludge, starch industry wastewater, and soya (commercial medium), were investigated. The selected suspending ...

This study investigated the amount of energy available to growing pigs from fermentation of dietary fiber in the hindgut. Eighteen growing barrows, fitted with a simple T-shaped cannula at the terminal ileum, were allocated to 3 experimental diets in a completely randomized design. The 3 diets were a standard-fiber diet (SFD), which contained 75.1 g NDF/kg diet; a medium-fiber diet (MFD) of 105...

In recent years, the use of microbial inoculants has been increasing in Brazil, although the results have been conflicting. This study was conducted to evaluate the effects of adding a by-product from amino acid production or biological inoculants on fermentative characteristics, chemical composition and aerobic stability of corn silage. The treatments were: Control (control silage without addi...

An in vitro experiment was conducted to determine the impact of silage produced from selected varieties sorghum on microbial fermentation profile cows’ ruminal fluid. To main products, fluid samples were obtained Polish Holstein–Friesian cows. Serum bottles filled with 80 mL samples, and 1 g one following substrates added: corn (CS), grass (GS), rye (RS), (sweet) (SS1), (grain) (SS2) or (dual-p...

To better understand the mechanism underlying water-soluble carbohydrates (WSC)-regulated silage fermentation, bacterial community and fermentation quality of stylo (Stylosanthes guianensis) ensiled without (sterile distilled water) (CK) or with 10 g/kg sucrose (S), glucose (G), molasses (M) were investigated. Each treatment was in three plastic bag silos for 30 days. The DM 301.0 (fresh matter...

We investigated the distribution of short chain fatty acids (SCFA) in enema samples taken from subjects before sigmoidoscopy as an indicator of possible microbial community differences between subjects subsequently diagnosed as normal or having colonic disorders. The major SCFA in all groups were acetic, propionic, and butyric acids. A significantly higher ratio of acetate to total SCFA and low...

Baleen whales have a multichambered stomach divided into three distinct compartments. The forestomach (first compartment) consists of noncornified and nonglandular tissue and appears to be analogous to the tissue of the rumen. The exact function of the forestomach is unknown; however, we have detected volatile fatty acids in forestomach samples from seven bowhead (Balaena mysticetus) and four g...

Salmonella typhimurium was adapted to acid by exposure to hydrochloric acid at pH 5.8 for one to two doublings. Acid-adapted cells had increased resistance to inactivation by organic acids commonly present in cheese, including lactic, propionic, and acetic acids. Recovery of cells during the treatment with organic acids was increased 1,000-fold by inclusion of 0.1% sodium pyruvate in the recove...

Nineteen new Corynebacterium species or taxa described since 1995 have been associated with human disease. We report the characteristics of 72 strains identified as or most closely resembling 14 of these newer, medically relevant Corynebacterium species or taxa, as well as describe in brief an isolate of Corynebacterium bovis, a rare pathogen for humans. The bacteria studied in this report were...
