Bottom Line: 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 endogenous FAs, exogenous FAs may positively or negatively affect the survival of Bacillus vegetative cells and the spore germination ability in a given environment.

ABSTRACT
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.

Figure 1: Different types of fatty acids (FAs) present in Bacillus species.

Mentions: Like other Gram-positive bacteria, Bacillus species have three main groups of FAs: branched-chain FAs, straight-chain FAs, and complex FA types (such as cyclic, hydroxyl or epoxy FAs; Harris, 1996; Figure 1). Compared with other genera of Gram-positive bacteria, such as Micrococcus, Clostridium, and Corynebacterium, the genus Bacillus is characterized by a relative homogeneity of its FA composition across species (Moss and Lewis, 1967; Harris, 1996). To date, no Bacillus strains have been described with only branched-chain or straight-chain FAs. Another characteristic of this genus is that linear saturated FAs such as C14:0 or C16:0, which are encountered in the majority of microorganisms, are generally minor constituents in the genus Bacillus (Kaneda, 1977). 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).
