Germination and growth of spores of butyric acid bacteria (BAB) may cause severe defects in semihard cheeses. Silage is the main source of BAB spores in cheese milk. The objectives of the study were to determine the significance of grass silages and corn silages as sources of BAB spores and to
Digesters produce biogas from organic wastes through anaerobic digestion processes. These digesters, often made of concrete, suffer severe premature deterioration caused mainly by the presence of fermentative microorganisms producing metabolites that are aggressive towards cementitious materials. To
Application of benzoic acid (0.2%) is a technological measure to prevent aerobic deterioration of maize silages caused by yeasts and moulds, particularly byP. roqueforti. Furthermore, benzoic acid inhibits undesired butyric acid fermentations.
The clostridial fermentation caused by the outgrowth of Clostridia was mainly responsible for the silage anaerobic deterioration. Our previous results showed that Clostridium perfringens dominated the clostridial community in poor-fermented alfalfa silage. This study was conducted to further examine
The outgrowth of Clostridium spore-forming bacteria causes late blowing in cheeses. Recently, the role of air diffusion during storage and feed-out and the role of aerobic deterioration has been shown to indirectly favor butyric acid bacteria (BAB) growth and to determine the presence of high
OBJECTIVE
To determine the properties of the retina of a rhodopsin P347L transgenic (Tg) rabbit model of retinal degeneration by electroretinography (ERG).
METHODS
Full-field ERGs were recorded in 12- to 48-week-old wild-type (WT) and Tg rabbits. The a-wave was analyzed by the a-wave fitting model
Clostridium tyrobutyricum ATCC 25755 is an acidogenic bacterium, producing butyrate and acetate as its main fermentation products. In order to decrease acetate and increase butyrate production, integrational mutagenesis was used to disrupt the gene associated with the acetate formation pathway in C.
Three non-lactating cows (Deutsches Schwarzbuntes Rind) with large ruminal fistulas were fed coarsely structured food. Within a trial period of 21 weeks infusion periods lasting 3 weeks alternated with equally long control periods (K). During the 3 infusion periods, 8.4 mMol of propionic acid (P),
BACKGROUND
Status epilepticus (SE) is an epileptic condition that can cause cerebellar atrophy and loss of Purkinje cells in both humans and research animals. Cerebellum is a region rich in γ-aminobutyric acid (GABA) and glutamate, and some studies have shown that their concentrations may be altered
We examined the pattern of cytochrome oxidase (CO), Nissl staining, and gamma-amino butyric acid (GABA) immunoreactivity in the ventroposterior lateral nucleus (VPL) of the thalamus in monkeys that received no, total, or subtotal, ablation of the hand representations in postcentral somatosensory
BACKGROUND
Parenteral nutrition (PN) causes intestinal mucosal atrophy, gut-associated lymphoid tissue (GALT) atrophy and dysfunction, leading to impaired mucosal immunity and increased susceptibility to infectious complications. Therefore, new PN formulations are needed to maintain mucosal
Zero drift can severely deteriorate the stability of the light-dark current ratio, detectivity, and responsivity of photodetectors. In this paper, the effects of a [6,6]-phenyl-C61-butyric acid methyl ester (PCBM)-doped perovskite-based photodetector device on the inhibition of zero drift under dark
Unless periodically grown from germinated spores, Clostridium acetobutylicum tends to degenerate (that is, to spontaneously lose the capacity both to produce solvents and to develop into spores). To obtain mutants that are deficient in degeneration, C. acetobutylicum NCIMB 8052 was mated with
Previous studies have shown that disruption of cyclic nucleotide metabolism by phosphodiesterase inhibitors and cyclic nucleotide analogues damages photoreceptors in rod-enriched retinae. In these studies the cone photoreceptors appeared damaged only after the surrounding rods had begun to
