Isolation and Identification of Streptomyces rochei Strain Active against Phytopathogenic Fungi

Abstract

This work was carried out in collaboration between all authors. Author AAEH designed the study, performed the statistical analysis, wrote the protocol and prepared the final draft of the manuscript. Author REMA conducted the major parts of the practical work. Author SAA did the identification of the fungal species. Author MAES managed the literature searches, wrote the first draft of the manuscript and performed DNA analysis. All authors read and approved the final manuscript.

Metabolomics-Based Chemotaxonomic Classification of Streptomyces spp. and Its Correlation with Antibacterial Activity

“…As shown in Table 2, 2-hydroxystaurosporinone (5), staurosporine (9), and three unidentified metabolites (1,8,17) were found in S. rubrolavendulae, whereas oxytetracycline (3), altamycin (4), rimocidin (13), and four unidentified metabolites (2,15,16,19) were detected in S. rimosus. Furthermore, three unidentified metabolites (10,11,12) were S. scabiei-specific metabolites, and strevertene A (14) and unidentified metabolites (21) were from S. virginiae.…”

“…Despite the wide variety of investigations, taxonomic approaches to identifying Streptomyces species remain difficult because of the various morphological, cultural, physiological, and biochemical characteristics that are observed at the interand intraspecies levels [1]. Recently, several studies using a chromatographic approach to classify bacteria have been reported [21,56,25]. The classification of microorganisms based on metabolite profiling has emerged as a useful chemotaxonomic tool that provides detailed information about the differences and similarities between species [7,32,51,58].…”

The Use of Plants to Protect Plants and Food Against Fungal Pathogens: A Review

“…These fungi collectively are responsible for 80% of plant diseases (El Hussein et al, 2014). About 8000 fungal species cause nearly 100 000 diseases in plants (Agrios, 2005).…”

Isolation and characterization of actinomycetes from marine soil

“…3 They are the largest antibiotic producing genus and about 70% of the antibiotics have been isolated from them. 4 They also produce other type of compounds that are deleterious to competing microbes 5 apart from a wide array of natural bioactive compounds such as antifungal, antiviral, anti-hypersensitivity, antitumor. 6,7 Bioactive compounds produced from Streptomyces are not only used in the treatment of human and animal diseases but also used as bio control agents.…”
