I realize that the strains causing these problems were wild strains, not strains studied to be probiotics. The maximum pectinase producing bacterial strain was identified as Bacillus licheniformis on the basis of morphological, physiological and biochemical characteristics. Bacillus is a rod-shaped, endospores forming, and facultative anaerobic bacteria. Background Direct-fed microbials (DFM), such as Bacillus subtilis and Bacillus licheniformis, may improve gut functionality of the host by favouring non-pathogenic bacteria and reducing the formation of putrefactive compounds. Only one endospore is formed per cell. Publication types Research Support, Non-U.S. Gov't MeSH terms This study presents the detailed contrastive potential of Bacillus licheniformis gram positive and Bacillus mucilaginosus Krassilnikov gram negative for Cr (VI) remediation from water. Bacillus licheniformis was found to be the only isolate in 3 cases of bovine abortion. Quorum quenching by T-1 was confirmed using C. violaceum CV026. Unlike other bacilli which are predominately aerobic, B. licheniformis is a facultative anaerobe, which explains it's ability to grow in additional ecological niches and environments. It is a motile bacterium, a facultative anaerobe (unlike other bacilli that are typically aerobic), and closely related to Bacillus subtilis.
