Phylum actinobacteria

Actinobacteria (Actinomycetes Actino-mycota) A phylum of Gram-positive mostly anaerobic nonmotile bacteria. Many species are fungus-like, with filamentous cells producing reproductive spores on aerial branches similar to the spores of certain moulds. The phylum includes bacteria of the genera. Actinomyces, some species of which cause disease in animals (including humans) and Streptomyces, which are a source of many important antibiotics (including streptomycin).

As previously mentioned. Bifidobacterium does not belong to the LAB group (Actinobacteria phylum) however, this genus shares many properties with lactobacilli, such as their probiotic characteristic and their ability to persist in the GIT for a long period of time. Bifidobacteria are also known to be a major component of mammals microbiota. Thus, these bacteria are excellent alternatives to be used as mucosal delivery vectors of heterologous proteins and to enhance innate and...
