Abstract
The extreme cold environments harbor novel psychrotrophic microbes. The psychrotrophic microbes have been reported as plant growth promoters and biocontrol agents for sustainable agriculture, in industry as cold-adapted hydrolytic enzymes and in medicine as secondary metabolites and pharmaceutical important bioactive compounds. Inoculation with psychrotrophic/psychrotolerant strains significantly enhanced root/shoot biomass and nutrients uptake as compared to non-bacterized control. The psychrotrophic microbes play important role in alleviation of cold stress in plant growing at high hill and low temperature and conditions. The psychrotrophic microbes have been reported from worldwide from cold habitats and belong to all three domain archaea, bacteria, and eukarya including different phylum such as Actinobacteria, Ascomycota, Bacteroidetes, Basidiomycota, Chloroflexi, Chlamydiae, Planctomycetes, Cyanobacteria, Euryarchaeota, Firmicutes, Gemmatimonadetes, Verrucomicrobia, Mucoromycota, Proteobacteria, Spirochaetes, Thaumarchaeota and Nitrospirae. The most dominant genera belong to Arthrobacter, Bacillus, Exiguobacterium, Paenibacillus, Providencia, Pseudomonas, and Serratia
