Studies on the Production of Broad Spectrum Antimicrobial Compound Polypeptide (Actinomycins) and Lipopeptide (Fengycin) from Streptomyces sp. K-R1 Associated with Root of Abutilon indicum against Multidrug Resistant Human Pathogens

Actinomycins produced by endophyte Streptomyces sp. GLL‐9 from navel orange plant exhibit high antimicrobial effect against Xanthomonas citri susp. citri and Penicillium italicum

“…Av-R5 isolated from aloe Vera rhizome produced a high yield of Act-D and Act-X O⊎ when using soybean meal as the culture medium after 10 days of fermentation time, while the production of Acts was completely inhibited by the addition of peptone to the culture medium. 58,60 However, in this study, the production yield of Acts for Streptomyces sp. GLL-9 fermented in liquid culture media was very low (Table S2 of Supplementary material).…”

“…Several recent studies reported that Streptomyces sp . cultured in liquid media produced a high yield of Acts 58,59 . In addition, Chandrakar and Gupta reported that the liquid fermentation of a strain Streptomyces sp .…”

Structural diversity, biosynthesis, and biological functions of lipopeptides fromStreptomyces

“…SSA 13 demonstrating potent antitumor activities. 190,191 Surfactins, iturins, and fengycins were found to be active against a variety of plant pathogens, making them efficient crop-protection agents. Their antimicrobial activities are mainly mediated by permeabilising cellular membranes.…”

Assessment of Antagonistic Potential of Bacteria as Biocontrol Agent Against Alternaria Leaf Spot of Turnip

“…Research reports suggest that B. subtilis produce various types of antimicrobial compounds such as peptides (kim et al, 2010) secreted enzymes, proteins (Baysal et al, 2013) and unstable organic substances (Tan et al, 2013) which make them appropriate and effective biocontrol agents (Baffoni et al, 2015). Streptomyces hydrogenans is an actinomycetes and gram-positive bacteria which plays a vital role in controlling pathogen by manufacturing cyclic lipopeptide fengycin (Chandrakar and Gupta, 2018). Due to production of enzymes, it hinders the expansion of possible fungal pathogens (Zaynab et al, 2018) which destroy the fungal cell wall (Errakhi et al, 2007;Getha et al, 2005).…”
