Biological control of major rice diseases has been attempted in several rice-growing countries in Asia during the last few decades and its application using antagonistic bacteria has proved to be somewhat successful for controlling various fungal diseases in field trials. Two novel endophytic Bacillus species, designated strains YC7007 and YC7010T, with anti-microbial, plant growth-promoting, and systemic resistance-inducing activities were isolated from the roots of rice in paddy fields at Jinju, Korea, and their multifunctional activities were analyzed. Strain YC7007 inhibited mycelial growth of major rice fungal pathogens strongly in vitro. Bacterial blight and panicle blight caused by Xanthomonas oryzae pv. oryzae (KACC 10208) and Burkholderia glumae (KACC 44022), respectively, were also suppressed effectively by drenching a bacterial suspension (107 cfu/ml) of strain YC7007 on the rhizosphere of rice. Additionally, strain YC7007 promoted the growth of rice seedlings with higher germination rates and more tillers than the untreated control. The taxonomic position of the strains was also investigated. Phylogenetic analyses based on 16S rRNA gene sequences indicated that both strains belong to the genus Bacillus, with high similarity to the closely related strains, Bacillus siamensis KACC 15859T (99.67%), Bacillus methylotrophicus KACC 13105T (99.65%), Bacillus amyloliquefaciens subsp. plantarum KACC 17177T (99.60%), and Bacillus tequilensis KACC 15944T (99.45%). The DNA-DNA relatedness value between strain YC7010T and the most closely related strain, B. siamensis KACC 15859T was 50.4±3.5%, but it was 91.5±11.0% between two strains YC7007 and YC7010T, indicating the same species. The major fatty acids of two strains were anteiso-C15:0 and iso C15:0. Both strains contained MK-7 as a major respiratory quinone system. The G+C contents of the genomic DNA of two strains were 50.5 mol% and 51.2 mol%, respectively. Based on these polyphasic studies, the two strains YC7007 and YC7010T represent novel species of the genus Bacillus, for which the name Bacillus oryzicola sp. nov. is proposed. The type strain is YC7010T (= KACC 18228T). Taken together, our findings suggest that novel endophytic Bacillus strains can be used for the biological control of rice diseases.

“…Bacillus species are also characterized by displaying three major polar lipids: the phospholipids phosphatidylethanolamine, phosphatidylglycerol, and diphosphatidylglycerol ( Bishop et al, 1967 ; Lang and Lundgren, 1970 ; Qiu et al, 2009 ; Zhai et al, 2012 ; Seiler et al, 2013 ; Yu et al, 2013 ; Choi and Cha, 2014 ; Jiang et al, 2014 ; Kosowski et al, 2014 ; Van Pham and Kim, 2014 ). However, some aminophospholipids are also found in the membranes of certain Bacillus strains ( Bishop et al, 1967 ; Kang et al, 2013 ; Seiler et al, 2013 ; Wang et al, 2013 ; Choi and Cha, 2014 ).…”

Role of fatty acids in Bacillus environmental adaptation

et al. 2015

The large bacterial genus Bacillus is widely distributed in the environment and is able to colonize highly diverse niches. Some Bacillus species harbor pathogenic characteristics. The fatty acid (FA) composition is among the essential criteria used to define Bacillus species. Some elements of the FA pattern composition are common to Bacillus species, whereas others are specific and can be categorized in relation to the ecological niches of the species. Bacillus species are able to modify their FA patterns to adapt to a wide range of environmental changes, including changes in the growth medium, temperature, food processing conditions, and pH. Like many other Gram-positive bacteria, Bacillus strains display a well-defined FA synthesis II system that is equilibrated with a FA degradation pathway and regulated to efficiently respond to the needs of the cell. Like endogenous FAs, exogenous FAs may positively or negatively affect the survival of Bacillus vegetative cells and the spore germination ability in a given environment. Some of these exogenous FAs may provide a powerful strategy for preserving food against contamination by the Bacillus pathogenic strains responsible for foodborne illness.

A Gram-staining-positive, endospore-forming, moderately alkaliphilic bacterium, strain NPK15T, was isolated from a typical sandy loam soil under long-term NPK fertilization in northern China and was subjected to a polyphasic taxonomic study. The diamino acid of the cell-wall peptidoglycan of strain NPK15T was found to be meso-diaminopimelic acid and the cell-wall sugars were xylose, glucose and traces of mannose. The only respiratory quinone found in strain NPK15T was menaquinone 7 (MK-7). The major cellular fatty acids were iso-C15 : 0, anteiso-C15 : 0, C16 : 0 and C16 : 1ω6c/C16 : 1ω7c. The major polar lipids were diphosphatidylglycerol, phosphatidylethanolamine and phosphatidylglycerol. Phylogenetic analysis of the strain based on its 16S rRNA gene sequence showed that it was related most closely to ‘ Bacillus thaonhiensis ’ KACC 17216 (99.59 %), B. songklensis KCTC 13881T (99.52 %) and B. abyssalis CCTCC AB 2012074T (99.00 %). DNA–DNA hybridization results indicated that the strain was distinct from other species of the genus Bacillus , the degree of relatedness being 35.4 % with B. abyssalis CCTCC AB 2012074T, 39.7 % with B. songklensis KCTC 13881T and 51.2 % with ‘ B. thaonhiensis ’ KACC 17216. The DNA G+C content of strain NPK15T was 45.5 mol%. Phenotypic, chemotaxonomic and molecular analyses identified strain NPK15T as a member of a novel species of the genus Bacillus , for which the name Bacillus fengqiuensis sp. nov. is proposed. The type strain is NPK15T ( = DSM 26745T = CCTCC AB 2013156T).
