The above ground growth of the plant is highly dependent on belowground root system. Rhizosphere zone continuous interplay between roots and soil microbial communities. Plants, through exudates, attract rhizosphere microorganisms to colonize surface internal tissues. Many these known as promoting rhizobacteria (PGPR) improve several direct indirect mechanisms including biological nitrogen fixation, nutrient solubilization, disease-control. PGPR, by producing phytohormones, volatile organic...

Abstract The unstable and uncertain availability of petroleum sources as well rising cost fuels have shifted global efforts to utilize renewable resources for the production greener energy a replacement which can also meet high demand world. Bioenergy routes suggest that atmospheric carbon be cycled through biofuels in carefully designed systems sustainability. Significant potential exists bioconversion biomass, most abundant biomaterial on our planet. However, requirements enzyme complexes...

Composting is microbial decomposition of biodegradable materials and it governed by physicochemical, physiological microbiological factors. The importance communities (bacteria, actinomycetes fungi) during composting well established. However, the diversity may vary with variety nutrient supplements. Therefore, necessary to study microorganisms different agricultural byproducts like wheat bran, rice husk, along grass clippings bulking agents. Here has been attempted assess culturable...

Abstract A set of seventy axenised and unicyanobacterial isolates belonging to the genus Anabaena were evaluated for biocidal activity against a phytopathogenic fungi. Among them, 35 strains showed zone inhibition one or more The extracellular filtrates from 4 8 weeks old cultures these further in terms hydrolytic enzymes, proteins IAA employing standard methods. Significant differences also observed among their FPase, chitosanase xylanase activity, while low relatively similar values...

Lignocellulosic biomass is the most abundant renewable source of energy that has been widely explored as second-generation biofuel feedstock. Despite more than four decades research, process ethanol production from lignocellulosic (LC) remains economically unfeasible. This due to high cost enzymes, end-product inhibition and need for cost-intensive inputs associated with a separate hydrolysis fermentation (SHF) process. Thermotolerant yeast strains can undergo at temperatures above 40°C are...

A pot experiment was undertaken under net house conditions, with three rhizobacterial strains AW1 (Bacillus sp.), AW5 (Providencia sp.) and AW7 (Brevundimonas applied along 2/3 recommended dose of nitrogen (N) full phosphorus (P) potassium (K) fertilizers (N90P60K60). An enhancement 14–34% in plant biometric parameters 28–60% micronutrient content recorded treatments receiving the combination + strains, as compared to fertilizer application. The treatment involving inoculation highest values...

The influence of plant growth promoting bacteria (PGPB) and cyanobacteria, alone in combination, was investigated on micronutrient enrichment yield rice–wheat sequence, over a period two years. Analysis variance (ANOVA) both crops indicated significant differences soil dehydrogenase activity grains (Fe, Zn rice, Cu, Mn wheat). combined inoculation Anabaena oscillarioides CR3, Brevundimonas diminuta PR7, Ochrobactrum anthropi PR10 (T6) significantly increased nitrogen, phosphorus, potassium...

A set of 300 bacterial strains isolated from various extreme environments were screened for the presence cellulase activity on CMC agar plates. Phylogenetic analysis positive strain, based 16S rRNA gene sequences indicated that isolates clustered within Firmicutes and Actinobacteria. majority (17) identified as Bacillus, Paenibacillus, Lysinibacillus sp., remaining three Arthobacter, Rhodococcus, Bhargavaea cecembensis. Among 20 isolates, 6 evaluated production cellulases five different...

The present investigation evaluated the effect of inoculating different cyanobacterial formulations on a set hybrids maize, in terms plant defense enzyme activity, soil health parameters, Zn concentration, and yields. Microbial inoculation showed significant effects accumulation flag leaf, with A4 (Anabaena–Azotobacter biofilm) recording highest values. Analysis variance (ANOVA) indicated that both treatments brought about variation glomalin-related proteins polysaccharides activity enzymes...

Microorganisms in the rhizosphere mediate cycling of nutrients, their enhanced mobilisation and facilitate uptake, leading to increased root growth, biomass yield plants. We examined promise beneficial cyanobacteria eubacteria as microbial inoculants, applied singly or combination consortia biofilms, improve growth yields okra. Interrelationships among activities micro/macro nutrient dynamics soils okra characteristics were assessed along with changes soil microbiome. A significant effect...

A proteolytic strain of Bacillus pumilus MP 27 was isolated from water samples Southern ocean produced alkaline protease. Since protease production need expensive ingredients, an economically viable process developed by using low cost carbon source, wheat straw, supplemented with peptone. This active within temperature ranges 10-70°C at pH 9. optimized response surface methodology a Box Bekhman design Design Expert 7.0 software that increased the activity to 776.5 U/ml. Moreover, enzyme...

A field experiment was conducted to evaluate the effect of different plant growth promoting microorganisms (PGPM) on micronutrient enrichment rice crops grown under conventional (flooded) and SRI (System Rice Intensification) practices. Significant differences were recorded among treatments cultivation practices in terms soil microbial activity reflected enhanced nutrient uptake, enzyme activity, yield. The Anabaena-based biofilm inoculants particularly superior both methods cultivation,...

An investigation was undertaken to explore the biocidal efficacy of fungicidal compound(s) produced by Calothrix elenkenii against damping-off disease in three vegetable crops-tomato, chilli and brinjal. Treatments included application seeds soaked water (control), culture filtrate ethyl acetate extract Metalaxyl potting mix inoculated with Pythium aphanidermatum plastic pots. The observations taken after a period four weeks revealed superiority seed treatment extracts, terms percent...

The present communication is an attempt to explore the synergistic effect of two indigenous phosphate solubilizing bacteria (PSB) (Pseudomonas fluorescens BAM-4 and Burkholderia cepacia BAM-12) arbuscular mycorrhizal (AM) fungus, Glomus etunicatum on growth, yield nutrient uptake wheat plants grown in deficient soils pots amended with tricalcium (TCP).A significant increase was noticed both strains PSB interacted positively AM fungus towards all growth parameters studied.A remarkable...
