Elicitation of Streptomyces lunalinharesii secondary metabolism through co-cultivation with Rhizoctonia solani

Computation-aided studies related to the induction of specialized metabolite biosynthesis in microbial co-cultures: An introductory overview

“…Notably, as many as 25 metabolites were detected exclusively in co-cultures and 4 of these molecules were marked as novel chemical entities [58] . The utilization of computational workflow for metabolite annotation in co-cultivation experiments was also reported by Maimone et al, who studied the co-cultures of Streptomyces lunalinharesii A54A with the phytopathogenic species Rhizoctonia solani and employed the GNPS library for the putative identification of desferrioxamines and anisomycin [56] . The examples of studies involving the application of GNPS tools and MN analysis include the co-cultures of Pleurotus ostreatus vs. Trametes robiniophila Murr [54] , Aspergillus sclerotiorum DX9 vs. Streptomyces sp.…”

Investigation of biological activity and identification of culturable insect-derived Streptomyces strains from Cossus chloratus

“…The actinomycetes were isolated from three samples of Cossus chloratus collected from Chanthaburi province (12.8397023°N, 102.1167445°E), Thailand. The preparation and isolation methods of insect-derived actinomycetes were modified from Hanshew et al (2015) and Maimone et al (2021). The insect samples were washed with sterile distilled water and surface-sterilized in 70% ethanol for 3 min, before rinsing in 3% sodium hypochlorite (NaOCl) for 2 min, followed by three repeated washes using sterile distilled water and then grinding with a mortar and pestle under sterile conditions.…”

Actinomycetes as a promising candidate bacterial group for the health management of aquaculture systems: A review

“…202,203 To increase BGC expression for potential natural products including antibiotics, new technologies and techniques must be used. 204 Recently, various methods in silent gene cluster activation have been reviewed by Liu et al 205 Other strategies to be investigated in actinomycetes for aquaculture use include the optimization of fermentation conditions, 206 microbial co-cultivation for the discovery of new antimicrobial candidates 207,208 as well as advanced techniques such as pathway/ metabolic engineering 209,210 and CRISPR/Cas9. 211,212 It is currently unclear how the native gastrointestinal (GI) microbiota and the added actinomycete probiotics interact.…”
