Selenium bioaccumulation by lactic acid bacterial: An alternative to animal production
Abstract
The selenium is an essential micronutrient for all living organisms. Low concentrations of this element in the animals can reduce the immunological, production and reproduction capacity of the animals. Lactic acid bacteria (LAB) from gastrointestinal and even in the food have shown many beneficial aspects to the host such as: antimi- crobial activity, antioxidant activity, control pathogens and microbial contamination, mucous protection of the gas- trointestinal system, and other benefits. Due to the high world production necessity, studies with the LAB enrichment with selenium can promote the meat production, and still can reduce the costs with diseases and natural pathogens present in the agriculture. Thus, the selenium bioaccumulation by LAB can be an efficient alternative in increasing animal production.
