“…have great potential to be used as biocontrol agents for management of F. oxysporum f. sp. ciceris causing chickpea Fusarium wilt as well as many other fungi pathogens that have been previously reported (Wan et al 2008;Li et al 2010;Elango et al 2015). These biocontrol agents not only reduced the disease severity but also increased growth parameters of chickpea plant.…”

“…Streptomyces strains can protect plants from pathogens by different mechanisms, including antibiosis (Smith et al 1990), competition for space and nutrients and (Tanaka and Omura 1993), like dimethyl disulfide, dimethyl trisulfied, acetophenone and 2-methylisoborneol (Li et al 2010), competition for iron through production of siderophores (Sadeghi et al 2012), induction of systemic resistance (Tarkka et al 2008), production of extracellular enzymes such as chitinase (Srividya et al 2012) and protease that can lyse cell walls of pathogen (Xiao et al 2002;Srividya et al 2012), and parasitism (Loliam et al 2013).…”

Abstract:In this study, about 112 isolates of Streptomyces were isolated from chickpea rhizospheric soils. Among the isolated strains, five showed strong inhibitory effects against chickpea Fusarium wilt caused by Fusarium oxysporum f. sp. ciceris in vitro using plate assay and selected for further studies. The selected strains were identified as Streptomyces spp. based on morphological and biochemical characterization as well as 16S rDNA sequences analysis. Our results assigned them to strains related to genus of Streptomyces.In vitro, antagonistic effects of Streptomyces strains against the disease were evaluated through the dual-culture method, volatile and non-volatile metabolites, siderophore, protease and chitinase production. All bacterial strains inhibited mycelial growth of the pathogen ranging from 26 to 44.2% in dual culture assay. The non-volatile extract of five of the Streptomyces strains inhibited more than 50% growth of the pathogen, whereas volatile compounds were less effective on mycelial growth inhibition (20.2 to 33.4%). The ability of the biocontrol agents to produce siderophore and protease were varied, whereas, production of chitinase was detected for all strains. Results of the greenhouse assay indicated that all biocontrol agents reduced disease severity (ranging from 38.7 to 54.8%).Accordingly, strain KS62 showed higher control efficacy (54.8%). In addition, the biomass of chickpea plants (plant height and dry weight) significantly increased in plants treated with Streptomyces strains compared to non-bacterized control. The results of this study showed that it may be possible to manage chickpea Fusarium wilt disease effectively by using Streptomyces species, as biocontrol agents. Therefore, evaluating their efficiency under field conditions is needed.

“…CF016, when exposed to VOCs for three days (Park et al, 2010). The volatile compounds dimethyl disulfide, dimethyl trisulfide, and acetophenone, isolated from Streptomyces globisporus, completely inhibited the growth of the plant pathogen Penicillium italicum after five days of exposure to a concentration of 0.1 μLmL -1 of air (Li et al, 2010). In the same way, an artificial mixture of VOCs, consisting of 20 compounds isolated from the fungus M. albus, was demonstrated to impair the development of various microorganisms, including C. gloeosporioides.…”

Anthracnose is an important plant disease and is the main disease affecting guava (Psidium guajava) post-harvest, leading to economic losses and limiting fruit export. Because of the indiscriminate use of fungicides, along with environmental and food safety concerns, alternative methods of disease control are warranted. The yeast Saccharomyces cerevisiae produces a mixture of volatile organic compounds (VOCs) that show in vitro antimicrobial activity against various phytopathogens, with the compounds 3-methyl-1-butanol (3M1B) and 2-methyl-1-butanol (2M1B) being primarily responsible for this activity. Considering the potential of using VOCs for controlling post-harvest anthracnose, this study aimed to evaluate the in vitro effect of 3M1B and 2M1B on the development of Colletotrichum gloeosporioides and C. acutatum, the causal agents of the disease in guava, and to elucidate the possible modes of action of these antimicrobials. The mycelial growth of the plant pathogens was inhibited similarly by 3M1B and 2M1B, and complete inhibition occurred at doses ≥1 μLmL -1 of air. Exposure of fungi to the VOCs increased the peroxidation levels of membrane lipids, indicating the occurrence of oxidative stress, in addition to increasing the non-selective permeability of the plasma membrane. Therefore, both 3M1B and 2M1B show potential to control C. gloeosporioides and C. acutatum.

“…S. globisporus had been described as a soil dwelling Gram positive bacteria with antibacterial, antifungal and antitumor activities [46,47]. Mutanolysin was isolated from S. globisporus, it is a muralytic enzyme that cleaves the β-N-acetylmuramyl-(1→4)-N-acetylglucosamine linkage of the bacterial cell wall polymer peptidoglycan-polysaccharide [48,49].…”

Streptomyces spp. were isolated from rhizospheric soils collected from Ngaka Modiri Molema District, North West Province, South Africa. Ten of these bacterial isolates were found to exhibit broad spectrum antimicrobial activity against test organisms with varying degree of activity. The cultural characteristics of the bacterial isolates were consistent with that of the members of the genus Streptomyces. Molecular identification of the potent bacterial isolates was carried out by amplifying the 16S rDNA gene; this gave the expected size of 1.5 kb and was sequenced. Further computational analysis including BLAST search and phylogenetic analysis were performed to correlate the bacterial isolates with other species of the genera in the database library. The computational analysis of the amplified 16S rDNA gene confirmed that the bacterial isolates are members of the genus Streptomyces with 89-100% sequence similarity. The phylogenetic analysis showed that the 10 bacterial isolates were divided into 3 major clusters with varying bootstrap values. The strain NWU195 formed a distinct phyletic line in the Streptomyces 16S rDNA gene tree suggesting a new strain. The 16S rDNA sequences of the bacterial isolates was submitted to the GenBank under the accession numbers JX284398-JX284407. The 16S rDNA gene sequence analysis is a significant tool for phylogenetic analysis of Streptomyces spp.
