By Dharumadurai Dhanasekaran and Yi Jiang

This ebook provides an introductory assessment of Actinobacteria with 3 major divisions: taxonomic rules, bioprospecting, and agriculture and commercial application, which covers isolation, cultivation equipment, and identity of Actinobacteria and construction and biotechnological power of antibacterial compounds and enzymes from Actinobacteria. additionally, this publication additionally offers a accomplished account on plant growth-promoting (PGP) and pollutant degrading skill of Actinobacteria and the exploitation of Actinobacteria as ecofriendly nanofactories for biosynthesis of nanoparticles, similar to gold and silver. This publication could be precious for the graduate scholars, academics, researchers, biotechnologists, and different execs, who're to improve and extend their wisdom approximately Actinobacteria within the box of Microbiology, Biotechnology, Biomedical technological know-how, Plant technology, Agriculture, Plant pathology, Environmental technology, and so forth.

KNF2047 Neopeptin A and B Table 5. 11. Nematode control It has been known for decades that effective control of plant-parasitic nematodes is dependent on chemical nematicides. Due to its ill effects with respect to the environmental hazards, hazardous nematicides have emphasized the need for new methods to control nematodes. Today, numerous microorganisms are recognized as antagonists of plant-parasitic nematodes.

At very low doses, these biolarvicides are highly effective against mosquito larvae and are completely safe to other nontarget organisms, environment, man, and wild life. Several varieties of microorganisms, including fungi, bacteria, and nematodes have been reported as strategies to biologically control the vectors. Specifically, Actinobacteria produce many important bioactive compounds of high commercial value and continue to be routinely screened for new bioactive substances. In a study made by Vijayan and Balaraman [89], extracellular secondary metabolites were produced from 35 different Actinobacterial isolates that showed high larvicidal activity against Culex and Anopheles mosquitoes.

The abundance of Gram-negative bacteria in animal feces presents a major challenge for the isolation of fecal actinobacteria. To eliminate Gram-negative bacteria and fungi and to obtain more unknown actinobacteria, some key points for sampling and isolation should be given attention. 5772/61457 First, based on the results of previous experiments, it is best to collect fresh fecal samples from wild animals living in original habitats. Second, the fresh samples should be dried at 25–28°C for 7 to 10 days.
