The detrimental effects of synthetic fungicides have increased the emphasis for biological control as an effective and safe sustainable alternative method. In present work, a potent rhizospheric actinobacterium MR14 showed broad spectrum antifungal plant growth promoting activities indicating potential to fulfill need. Phylogenetic analysis confirmed that isolate could be assigned new species Streptomyces, coded Streptomyces sp. MR14. It formed clade with daghestanicus but very low bootstrap...
Biocontrol agents and their bioactive metabolites provide one of the best alternatives to decrease use chemical pesticides. In light this, present investigation reports biocontrol potential Streptomyces hydrogenans DH16 its towards Alternaria brassicicola, causal agent black leaf spot damping off seedlings crucifers. vitro antibiosis strain against pathogen revealed complete suppression mycelial growth pathogen, grown in potato dextrose broth supplemented with culture supernatant (20% v/v)...
AbstractThe objective of this study was the isolation and screening actinomycete isolates for antagonistic potential plant growth promoting activities. A total 321 were recovered from different plants, their rhizospheric soils non-rhizospheric Punjab Himachal Pradesh regions. Out these, 62 endophytic, 156 103 isolates. In primary (dual culture assay), 83 antagonised one or more test phytopathogenic fungi. From these active isolates, 20 found to be in well diffusion assay (secondary...
Destructive impacts of insecticides on non targeted populations necessitate the development an eco friendly pest control method. Streptomyces spp. are rich source bioactive secondary metabolites which may provide valuable alternatives to chemical insect-control agents as they can be less toxic and readily biodegradable. Because its potent biocontrol attributes, ethyl acetate extract hydrogenans DH16, a soil isolate, was tested assess anti-insect potential against polyphagous noctuid,...
Purpose: The rapid emergence of drug resistance among pathogenic bacteria, especially multidrugresistant underlines the need to look for new antibiotics.Methods: In present study, 134 different actinomycetes, isolated from soil samples collected localities Punjab and Himachal Pradesh, were screened antimicrobial activity against various test organisms including multidrug-resistant methicillin-resistant Staphylococcus aureus (MRSA) Escherichia coli in order identify potential antibiotic...
In the present study, an actinobacterium strain, possessing antagonistic activity against different fungal phytopathogens viz. Colletotrichum acutatum , Cladosporium herbarum Alternaria brassicicola Exserohilum sp., mali gleospoiroides alternata, Cercospora Fusarium oxysporum f.sp . dianthi and moniliformae was isolated from soil identified as Streptomyces hydrogenans DH16. Application of culture supernatant (5%)/cells (10 7 cfu ml −1 ), 2 h post inoculation with A. 5 spores resulted in...
In agriculture, biocontrol agents have been emerged as safe alternative to chemical pesticides where Streptomyces spp. and their metabolites constitute a great potential for exploration potent controlling various fungal phytopathogens. The present study reports an antifungal compound purified from hydrogenans strain DH16, soil isolate, using silica gel chromatography semi preparative HPLC. was characterized spectroscopic techniques (IR, (1)H (13)C NMR) named...
Purpose: Linezolid is an effective drug against methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant enterococci (VRE). We describe the emergence of linezolid resistance in MRSA VRE from India. Material Methods: One two strains were isolated a patient on therapy one week duration. All three isolates resistant to with minimal inhibitory concentrations (MIC) ≥4 mg/L. The 746-bp region flanking possible G2576U mutation corresponding DNA 23S rRNA was amplified by...
Proteinaceous extract obtained from Cassia occidentalis seeds with purification fold of 3.91 and 82.7% bovine trypsin inhibitory activity was assessed at different concentrations (25, 50, 100, 200, 400 800 μg/ml) against Spodoptera litura. Assay larval feeding suggested proteinaceous to be toxic as prepupal (80.16%) pupal mortalities (100%) along growth deterrent effect only 16.71% pupation observed μg/ml. Fifty per cent mortality (LC50) 132.91 Also the inhibitor affected fecundity,...
Abstract Study question Can a mAC-FET protocol for endometrial preparation in ovulatory patients lead to formation of CL as evidenced by serum relaxin-2 the pregnant patients? Summary answer forms early pregnancy was comparable that spontaneous conception.Late luteal rise wasn’t demonstrated. What is known already Clinical evidence points increased incidence preeclampsia pregnancies AC-FET cycles compared FET cycles-natural cycle(NC) and mNC. The absence it’s secretory products like...
