Biosurfactant Production From Halophilic Bacteria And Their Biological Applications

Abstract

newline The marine ecosystem represents an unexplored source of new microbes that are potent producer of bioactive secondary metabolites (Kalyani and Hemalatha, 2016). The marine environment holds the great path to discover the novel bioactive metabolites including compatible solutes, vitamins, enzymes, antibiotics and drugs etc. Various microorganisms such as bacteria, fungi, actinomycetes and algae possess different morphological, physiological and ecological characteristics (Das et al., 2006). Halophiles are a type of extremophile organisms that are adapted to hyper-saline environments and synthesize various metabolites that cannot be present everywhere (Antoniou et al., 2015). Currently, research is focused on the halophilic and halotolerant bacteria because of their, distinctive features, like a salt tolerant proteins, highly saline cytoplasm and light-driven proton and chloride pumps such as, bacteriorhodopsin and halorhodopsin (DasSarma and DasSarma, 2017; Ma et al., 2010). Halophilic bacteria have numerous biotechnological applications includes the synthesis of compatible solutes, biopolymers and antibiotics were used for different ecological bioremediation process (Weinisch et al., 2018; Manikandan and Senthilkumar, 2017). newlineThe complete sequencing of microbial genome is vital for generating precise reference genomes, for microbial recognition, and other relative genomic studies. Whole genome sequencing (WGS) of microorganisms holds huge promise for clinical diagnosis, public health microbiology and also for understanding the production mechanisms of microbial natural products (Kamada et al., 2014). We screened marine environment and isolated the moderately halophilic bacteria from Indian Arabian coastline sea water (17.24° N, 73.37° E) and exploited for antibacterial BSs. We report here the draft genome sequence of Bacillus aquimaris strain SAMM (Waghmode et al., 2017) and Planococcus maritimus SAMP. Further, P. maritimus reported as a candidate bacterium for bioactive product such as, surfactant.
