Antagonistic actinomycetes from Moroccan soil to control the grapevine gray mold
TLDR
It is demonstrated here that pre-inoculation of plantlets with these isolates allow them to withstand Botrytis cinerea, indicating the potential of developing effective actinomycetes from Moroccan habitats for the biological control of Botrytic mold.Abstract:
One hundred and forty-two different actinomycete strains were isolated from rhizosphere soil of Vitis vinifera L. sampled from four Moroccan areas. To evaluate the antifungal effect of the different collected actinomycete isolates, five fungi known to be phytopathogens (Pythium ultimum, Fusarium oxyysporum f. sp. albedinis, Sclerotium rolfsii,Verticillium dahliae and Botrytis cinerea) were used. Results showed that 24 isolates had an in vitro inhibitory effect toward at least 4 of the indicator fungi, but only 9 inhibited all these phytopathogens. These nine isolates were subsequently evaluated individually using in vitro grapevine plantlets for their ability to protect against plant gray mold. We demonstrate here that pre-inoculation of plantlets with these isolates allow them to withstand Botrytis cinerea. Six of these strains were shown to belong to the genus Streptomyces and three to the genus Micromonospora. These findings indicate the potential of developing effective actinomycetes from Moroccan habitats for the biological control of Botrytis cinerea.read more

Screening of Antagonistic Actinomyces for the Preparation of Bioactive Crude Extract and Development of Starter Culture Powder for Suppression of Rice Pathogen
TL;DR: Streptomyces hygroscopicus strain SWU-TH39 showed the highest inhibition zone against both Xoo and rice pathogenic fungi and was adapted to the development of starter culture in powder formulation and, remarkably, this was successful as a carrier to maintain bacterial survival with 8x10 8 CFU/g after 6-month storage at room temperature.

Protective Streptomyces in beewolves : ecology, evolutionary history and specificity of symbiont-mediated defense in Philanthini wasps (Hymenoptera, Crabronidae)
TL;DR: This thesis investigates the unique symbiotic association of beewolf wasps with antibiotic producing Streptomyces bacteria, which provides an antimicrobial defense against pathogen infestation by producing a cocktail of different antibiotic substances, thereby significantly enhancing the survival probability of the wasp offspring during their long and vulnerable phase of hibernation.

TL;DR: A Gram-stain positive, filamentous bacterial strain was isolated from the rhizosphere of a marigold plant collected in Heilongjiang Province, northeast China, and characterized using a polyphasic approach, and it is proposed that strain NEAU-TWSJ13T represents a novel species of the genus Streptosporangium.

Streptomyces luteolifulvus sp. nov., a novel actinomycete isolated from soil in Nanjing, China
TL;DR: A combination of low level of DNA-DNA relatedness and physiological properties indicated that strain HIT-DPA4T can be distinguished from its phylogenetically related species Streptomyces cyaneus CGMCC 4.1671 T.
