Modulación de los niveles de receptores germinantes y su efecto sobre la germinación de bacillus subtilis

Abstract

The spores of Bacillus species are extremely resistant to a variety of treatments and when they germinate are the cause of the decomposition of food and diseases produced by them. Germination begins with the presence and interaction of nutrients with their respective receptors present in the inner membrane of the spore. In the present work, the effect of environmental and genetic factors on the expression of germinating receptors was evaluated. In spores prepared in minimal medium, less germination was observed compared to spores obtained in an enriched medium, this difference is attributed to a lower number of spore receptors prepared in minimal medium
