“…The amendment of soil with certain organic substrates, particularly chitin, has been shown to increase the prolifération of Streptomyces (Kutzner 1981), as well as their production of chitinases (Trejo-Estrada et al 1998). We also showed that mature composts amended with chitin residues acquired suppressive properties against several plant pathogens (Côté et al 2001;Labrie et al 2001;Roy et al 1997).…”

“…Subséquent studies of YCED9 revealed that it produced three antimicrobial compounds. Thèse included nigericin, geldanamycin, and a fungicidal complex of polyene-like compounds termed AFA (Ant\-F usa ri u m Activity) that included guanidylfungin A (Trejo-Estrada et al 1998). The composition of the média in which YCED9 was grown was found to play a key rôle in the production of each of thèse metabolites.…”

“…It is proposed that the production of antibiotics increases an organism aptitude for survival in the former case by acting as an alternative (chemical) défense mechanism (Maplestone et al 1992). Several studies hâve reported antagonism between actinomycetes and a diversity of phytopathogens such as Altemaria, Fusarium, Macrophomina, Phytophthora, Pythium, Rhizoctonia, Verticillium (Chattopadhyay and Nandi 1982;Heisey and Putnam 1986;Hussain et al 1990;Iwasa et al 1970;Merriman et al 1974;Gottlieb 1981, 1984;Sabaou and Bounaga 1987;Trejo-Estrada et al 1998;Valois et al 1996;Wadi and Easton 1985).…”

Les actinomycètes représentent une grande proportion de la biomasse microbienne du sol et ont la capacité de produire une large variété d’antibiotiques et d’enzymes extracellulaires. Plusieurs souches d’actinomycètes s’avèrent capables de protéger les plantes contre des maladies. Cette revue se penche sur le potentiel des actinomycètes comme (a) source de composés agronomiques, (b) agents stimulant la croissance des plantes et (c) agents de lutte biologique. La revue donne aussi des exemples de lutte biologique contre les agents phytopathogènes bactériens et fongiques par l’utilisation d’espèces d’actinomycetes déjà disponibles sur le marché ou qui le seront probablement au cours des prochaines années.Actinomycetes represent a high proportion of the soil microbial biomass and have the capacity to produce a wide variety of antibiotics and of extracellular enzymes. Several strains of actinomycetes have been found to protect plants against plant diseases. This review focuses on the potential of actinomycetes as (a) source of agroactive compounds, (b) plant growth promoting organisms, and (c) biocontrol tools of plant diseases. This review also addresses examples of biological control of fungal and bacterial plant pathogens by actinomycetes species which have already reached the market or are likely to be exploited commercially within the next few years

“…can produce a wide variety of secondary metabolites including antibiotics, enzymes and alkaloids, which may be the causative agent for antagonistic activity (Hayakawa et al, 1996). Bioactive compounds such as benzoquinones (Rothrock and Gottlieb, 1984), aminoglycosides (Godfrey, 1995;Qin et al, 1994), polyenes (Smith et al, 1990;Raatikainen et al, 1994), nucleoside antibiotics (Hwang et al, 1994;Trejo-Estrada et al, 1998) are some agriculturally useful metabolites produced by genus Streptomyces. Several members of genus Streptomyces have been reported to significantly inhibit growth of plant fungal pathogens (Taechowisan et al, 2005;Maldonado et al, 2010;Evangelista-Martinez, 2014).…”

A b s t r a c tThe prospective of endophytic microorganisms allied with medicinal plants is disproportionally large compared to those in other biomes. The use of antagonistic microorganisms to control devastating fungal pathogens is an attractive and eco-friendly substitute for chemical pesticides. Many species of actinomycetes, especially the genus Streptomyces, are well known as biocontrol agents. We investigated the culturable community composition and biological control ability of endophytic Streptomyces sp. associated with an ethanobotanical plant Schima wallichi. A total of 22 actinobacterial strains were isolated from different organs of selected medicinal plants and screened for their biocontrol ability against seven fungal phytopathogens. Seven isolates showed significant inhibition activity against most of the selected pathogens. Their identification based on 16S rRNA gene sequence analysis, strongly indicated that all strains belonged to the genus Strepto myces. An endophytic strain BPSAC70 isolated from root tissues showed highest percentage of inhibition (98.3 %) against Fusarium culmorum with significant activity against other tested fungal pathogens. Phylogenetic analysis based on 16S rRNA gene sequences revealed that all seven strains shared 100 % similarity with the genus Streptomyces. In addition, the isolates were subjected to the amplification of antimicrobial genes encoding polyketide synthase type I (PKS-I) and nonribosomal peptide synthetase (NRPS) and found to be present in most of the potent strains. Our results identified some potential endophytic Streptomyces species having antagonistic activity against multiple fungal phytopathogens that could be used as an effective biocontrol agent against pathogenic fungi. K e y w o r d s: Schima wallichii, biocontrol agent, endophytic Streptomyces, nonribosomal peptide synthetase (NRPS), polyketide synthase (PKS-I)

“…Both chitin and chitosan have been used to remove a diverse range of compounds from waste streams including heavy metals [7] and dyes [8,9]. Chitin has also been used in the microbial production of chitinases as fungal control agents [10,11] and as a source of polyene antibiotics produced by a number of species of Monascus [12]. More recently, it was shown that a strain of Pseudomonas fluorescens cultured on chitin produced thermally stable antifungal compounds active against a number of phytopathogens [13].…”

Chitin in a dual role as substrate for Streptomyces griseus and as adsorbent for streptomycin produced during fermentation

Streptomycin production from chitin by Streptomyces griseus was compared using two different types of bioreactor. The first was equipped with a combined U-shaped paddle and Rushton impeller. Also employed was a bioreactor of novel design in which the chitin was contained in a wire mesh basket that was totally submerged in a liquid salts medium. During operation the chitin was gently fluidised by air admitted into the basket. Fermentation was continued in both bioreactors until maximum antibiotic titres were achieved whereupon operation was interrupted to allow the streptomycin adsorbed to the chitin substrate to be extracted into pH 3.0 buffer before continuing fermentation of the same batch of chitin a second time. At a chitin concentration of 10 % (w/v) the highest streptomycin yields (c. 5.5 mg/L) were obtained using the stirred bioreactor, however growth occurred more rapidly in the vertical basket bioreactor.
