Most of the bacteria were found to be aerobic or facultative bacteria, which are often highly versatile in their abilities to degrade aromatic and heterocyclic compounds (Chen et al. 1993; Barkovskii et al. 1995; Roldán et al. 1998; Song et al. 2003; Fournier et al. 2005).
Handled by Wuju Li Enterobacteriaceae are a family of gram-negative, rod-shaped, facultative anaerobic bacteria, which are mainly recognized for their ability to cause intestinal diseases [1].
The genus Methylobacterium is composed of pink-pigmented facultative methylotrophic (PPFM) bacteria, which are able to synthesize carotenoids and grow on reduced organic compounds containing one carbon (C1), such as methanol and methylamine.
Second, Bacillus subtilis (ATCC 6633) is another GRAM+ bacteria, which is a facultative pathogen commonly found in the soil [ 29].
Enterococcus faecalis is a gram-positive facultative anaerobic bacterium, which is present in 30 89% of teeth with postendodontic treatment failures.
Purple nonsulfur bacteria (PNSB) are facultative photosynthetic bacteria and exhibit an extremely versatile metabolism.
Many bacteria are facultative anaerobes that can take their oxygen or leave it.
Propionibacterium acnes, which is a facultative anaerobic gram-positive bacterium, is believed to play a critical role in the induction and maintenance of inflammation in acne by activating inflammatory cells, keratinocytes, and sebocytes to induce various inflammatory mediators [ 3, 23].
LAB species frequently encountered in the beer environment belong to the genera Lactobacillus and Pediococcus, which are both Gram-positive, facultative anaerobic, chemo-organotrophic bacteria of the family Lactobacillaceae of the Firmicutes phylum.
