The effects of yeast extract (X1), NH4NO3 (X2), peptone (X3), urea (X4), CMC (X5), Tween 20 (X6), MgSO4 (X7), and CaCO3 (X8) on production of xylanase from Cellulosimicrobium cellulans CKMX1 were optimized by statistical analysis using response surface methodology (RSM). The RSM was used to optimize xylanase production by implementing the Central composite(More)
Alkalophilic Cellulosimicrobium cellulans CKMX1 isolated from mushroom compost is an actinomycete that produces industrially important and environmentally safer thermostable cellulase-free xylanase, which is used in the pulp and paper industry as an alternative to the use of toxic chlorinated compounds. Strain CKMX1 was previously characterized by metabolic(More)
A collection of 50 rhizospheric and 43 endorhizospheric bacteria was obtained from Podophyllum hexandrum grown in high hills of Churdhar, Himachal Pradesh, India and subjected to replica plating for one step screening of plant growth promoting (PGP) traits. After replica plating, 41 bacterial isolates simultaneously growing on Pikovskaya’s, Chrome-azurol-S,(More)
Alkalophilic Cellulosimicrobium cellulans CKMX1 isolated from mushroom compost is first report on actinomycetes that has the ability to produce thermostable cellulase-free xylanase, which is an important industrial enzyme used in the pulp and paper industry. Strain CKMX1 was characterized by metabolic fingerprinting, whole-cell fatty acids methyl ester(More)
Microbial xylanases and associated enzymes degrade the xylans present in lignocellulose in nature. Xylanase production by Cellulosimicrobium sp. CKMX1, isolated from mushroom compost, produced a cellulase-free extracellular endo-1, 4-β-xylanase (EC at 35 °C and pH 8.0. Apple pomace—an inexpensive and abundant source of carbon—supported maximal(More)
One hundred and six P-solubilizing bacteria (PSB) from rhizosphere soil (RS) and root endosphere (ER) of Hippophae rhamnoides L.(Sea-buckthorn) of two locations viz. Lahaul and Spiti of Himachal Pradesh were isolated using culture-dependent procedures and were screened for various plant growth-promoting traits (PGPTs). Indole acetic acid produced was(More)
The use of fungicides is the continuous exercise particularly in orchard crops where fungal diseases, such as white root rot, have the potential to destroy horticultural crops rendering them unsaleable. In view of above problem, the present study examines the effect of different concentrations of mancozeb (0-2000 ppm) at different incubation periods for(More)
A thermostable extracellular alkaline protease producing Bacillus amyloliquefaciens SP1 was isolated from apple rhizosphere having multifarious plant growth promoting activities. Strain SP1 was purified to 6.48-fold using four-step purification protocol and characterized in detail for its robustness and ecofriendly application in leather and detergent(More)
Aneurinibacillus aneurinilyticus strain CKMV1 was isolated from rhizosphere of Valeriana jatamansi and possessed multiple plant growth promoting traits like production of phosphate solubilization (260mg/L), nitrogen fixation (202.91nmolethylenemL-1h-1), indole-3-acetic acid (IAA) (8.1μg/mL), siderophores (61.60%), HCN (hydrogen cyanide) production and(More)
The use of plant growth promoting rhizobacteria (PGPR) is steadily increasing in agriculture and offers an attractive way to replace chemical fertilizers, pesticides, and supplements. The authors have isolated and characterized different PGPRs from the rhizosphere soils/roots of tomato with multiple plant growth promoting activities. Subsequently, to(More)
