Alkali production by oral bacteria and protection against dental caries.
pH is a key environmental factor affecting the physiology, ecology and pathogenicity of the oral biofilms colonizing the hard tissues of the human mouth. Much attention has been focused on the production of organic acids through the metabolism of carbohydrates by pathogenic oral bacteria. Now, evidence is emerging that alkali generation, particularly through ammonia production from arginine and...
متن کاملThe gene stlA encodes a phenylalanine ammonia-lyase that is involved in the production of a stilbene antibiotic in Photorhabdus luminescens TT01.
Photorhabdus is a genus of Gram-negative bacteria from the family Enterobacteriaceae. Members of Photorhabdus have a complex life cycle during which the bacterium has a pathogenic interaction with insect larvae whilst also maintaining a mutualistic relationship with nematodes from the family Heterorhabditidae. During growth in the insect, Photorhabdus bacteria produce a broad-spectrum antibioti...
متن کاملTitle: Alternative feedstuffs for reducing ammonia and odor emissions in pork production systems and improving the pig‟s gut health – NPB #06-117
Nutrition can help reduce the impact of pork production on the environment and improve pig gut health. The formulation of diets based on highly-digestible feedstuffs and which meet the exact requirements of the pigs, markedly reduces the excretion of minerals such as nitrogen and phosphorus into the environment. The presence of fermentable dietary fiber in the diet can also decrease the emissio...
متن کاملMicrobiological biodiversity in poultry and paddy straw wastes in composting systems
Immense quantity of waste is generated in association with poultry meat egg and crop production. The potential risks due to disposal of these wastes are magnified as a result of dense refinement of poultry production and the decreasing amount of land available for waste disposal. The study aims at studying the microbiological biodiversity of poultry waste and paddy straw based co-composting sys...

Submit Manuscript | http://medcraveonline.com of the use of antibiotics, however, its use promotes direct and indirect effects. Among the direct effects, the elimination of pathogens from the gastrointestinal tract, and indirectly effects, improvement in nutrient absorption, lower energy and protein expenditure, lower ammonia production, and a lower rate of food passage, and others. Among the h...
