Thermophilic and alkaliphilic Actinobacteria: biology and potential applications.

Shivlata L, Satyanarayana T - Front Microbiol (2015)

Bottom Line: Microbes belonging to the phylum Actinobacteria are prolific sources of antibiotics, clinically useful bioactive compounds and industrially important enzymes.The focus of the current review is on the diversity and potential applications of thermophilic and alkaliphilic actinobacteria, which are highly diverse in their taxonomy and morphology with a variety of adaptations for surviving and thriving in hostile environments.The specific metabolic pathways in these actinobacteria are activated for elaborating pharmaceutically, agriculturally, and biotechnologically relevant biomolecules/bioactive compounds, which find multifarious applications.

ABSTRACT
Microbes belonging to the phylum Actinobacteria are prolific sources of antibiotics, clinically useful bioactive compounds and industrially important enzymes. The focus of the current review is on the diversity and potential applications of thermophilic and alkaliphilic actinobacteria, which are highly diverse in their taxonomy and morphology with a variety of adaptations for surviving and thriving in hostile environments. The specific metabolic pathways in these actinobacteria are activated for elaborating pharmaceutically, agriculturally, and biotechnologically relevant biomolecules/bioactive compounds, which find multifarious applications.

Phylogram indicating the placement and relatedness of some alkaliphilic, alkalitolerant, alkalithermophilic and alkalithermotolerants actinobacterial strains belonging to two classes (Actinobacteria and Nitriliruptoria) of the phylum Actinobacteria. The numbers given at branch nodes indicate (%) bootstrap value. Bar 0.02 substitutions per 100 nucleotide positions.

The numbers given at branch nodes indicate (%) bootstrap value. Bar 0.02 substitutions per 100 nucleotide positions.

Mentions: Some alkaliphilic actinobacterial species belonging to the genus Streptomyces (Mikami et al., 1982), Micromonospora (Jiang and Xu, 1993), Nocardioides (Yoon et al., 2005), Microcella (Tiago et al., 2005), Cellulomonas (Jones et al., 2005), Nesterenkonia (Luo et al., 2009), Streptosporangium (Gurielidze et al., 2010), Corynebacterium (Wu et al., 2011b), Georgenia (Srinivas et al., 2012), Nocardiopsis, Isoptericola, Nesterenkonia (Ara et al., 2013), Saccharomonospora (Raut et al., 2013), Saccharothrix (Jani et al., 2014), and Arthrobacter (Kiran et al., 2015) have been isolated and well-characterized. Among them, the genus Nocardiopsis has been found to be prominent in alkaline environments (Ara et al., 2013). All the genera belong to the class Actinobacteria except the genus Nitriliruptor that belongs to the class Nitriliruptoria (shown in Figure 2). There are a few well-characterized alkalitolerant species such as Citricoccus alkalitolerans (Li et al., 2005), Spinactinospora alkalitolerans (Chang et al., 2011), and Haloactinopolyspora alkaliphila (Zhang et al., 2014) which proliferate in sites ranging from neutral to alkaline pH.
