“…Specifically, host plants showed significantly less root and crown rot, and were healthier overall (El-Tarabily et al, 2009). A number of other studies have shown similar results, in various plant systems, where root-inoculated actinomycetes were able to protect the plant from harmful pathogen invasion (Xue et al, 2013; Nabti et al, 2014; Solans et al, 2016). In a notable example, Streptomyces lividans was shown to produce prodiginines on the roots of Arabidopsis thaliana , which antagonized the particularly damaging fungal pathogen Verticillium dahlia (Meschke et al, 2012).…”

Actinomycetes, filamentous actinobacteria found in numerous ecosystems around the globe, produce a wide range of clinically useful natural products (NP). In natural environments, actinomycetes live in dynamic communities where environmental cues and ecological interactions likely influence NP biosynthesis. Our current understating of these cues, and the ecological roles of NP, is in its infancy. We postulate that understanding the ecological context in which actinomycete metabolites are made is fundamental to advancing the discovery of novel NP. In this review we explore the ecological relevance of actinomycetes and their secondary metabolites from varying ecosystems, and suggest that investigating the ecology of actinomycete interactions warrants particular attention with respect to metabolite discovery. Furthermore, we focus on the chemical ecology and in situ analysis of actinomycete NP and consider the implications for NP biosynthesis at ecosystem scales.

Halophilic bacteria are categorized based on their requirements to salt. They apply some strategies in adaptation to the high saline environment. Their low nutritional requirements and resistance to high concentrations of salt, introduce as potent agents in wide range of biotechnological applications. Halophilic bacteria are very divergent and more than 150 species introduce in 70 genera of halophilic bacteria are reported. Use of resistant microorganisms and their metabolites under harsh industrially conditions is a strikingly important subject. Various halophilic enzymes in different enzymatically processes, compatible solutes as macromolecule stabilizers, biopolymers, biofertilizers and pharmaceutically active molecules from halophilic bacteria are among the important applications of these group. Additionally, they have many potential in bioremediation of various organic and inorganic pollutants from environment. This chapter covers the different aspects of potential applications of halophilic bacteria in biotechnology. Keywords IntroductionMicrobial life exists in hypersaline habitat refl ects the adaption of microorganisms to high concentration of salts. Halophilic and halotolerant organisms are found in all three domains of life: Archaea , Bacteria , and Eukarya . According to the requirement

“…Barley (Hordeum vulgare L.) is one of the world's most extensively cultivated crops and the most salt tolerant cereal, reported to become seriously damaged only after extended periods at salt concentrations higher than 250 mM NaCl (equivalent to 50% seawater) (Munns et al, 2006). As far in our knowledge not many studies have been done in plant growth promotion by PGPR on barley (H. vulgare L.) (Omar et al, 2009;Chang et al, 2014;Hmaeid et al, 2014;Nabti et al, 2014) probably due to its natural salt tolerance compared to other agricultural crops such as corn, soybean, wheat, tomato and rice. Therefore, increasing research on PGPR strains to ameliorate salt plant stress on barley will help to improve its natural tolerance on fields and also its potential use in salt remediation of salt impacted soils (Chang et al, 2014).…”
