Benzo[a]pyrene is considered as a priority pollutant because of its carcinogenic, teratogenic and mutagenic effects. The highly recalcitrant nature poses major problem for degradation. White-rot fungi such Pleurotus ostreatus can degrade by enzymes like laccase manganese peroxidase. present investigation was carried out to determine the extent degradation PO-3, native isolate P. ostreatus, in presence heavy metals ligninolytic enzyme mediators. Modified mineral salt medium supplemented with...
Azo, anthroquinone and triphenylmethane dyes are the major classes of synthetic colourants, which difficult to degrade have received considerable attention. Congo red, a diazo dye, is considered as xenobiotic compound, recalcitrant biodegradative processes. Nevertheless, during last few years it has been demonstrated that several fungi, under certain environmental conditions, able transfer azo non toxic products using laccases. The aim this work was study factors influencing mycoremediation...
A laccase produced by Pleurotus ostreatus MTCC 142 under solid-state fermentation using co-substrates of paddy straw and corn husk (1.5:1.5, g w/w) showed an activity 2.54 U gds−1. Laccase was determined spectrophotometrically 0.5 mM 2,2′- azino-bis (3-ethylbenzthiazoline-6-sulphonic acid) (ABTS). Supplementation with fructose potassium nitrate resulted in maximum enzyme production at initial pH 5.8 ± 0.2 moisture content 70%. carbon: nitrogen ratio 0.5:0.1 yielded highest the presence...
An extracellular lipase with 23,666.66 U/ml/min activity was produced by Aspergillus tamarii JGIF06 under submerged fermentation in mineral salt medium containing coconut oil (2.5 % v/v), tryptone (2 w/v) and ammonium chloride w/v), initial pH of 5 ± 0.2, incubated at 25 °C for 7 days on a rotary shaker 120 rpm. A 7.9-fold increase lipase-specific recorded after purification DEAE Sepharose ion exchange Sephadex G200 column chromatography. The apparent molecular mass this enzyme revealed as...
Endophytic fungi are the plant symbiont with highly diverse nature and poorly defined ecological importance in host fitness. Although there reports on isolation characterization of fungal endophytes from a variety hosts, is still no report Penicillium citrinum Azadirachta indica. In this study, an endophytic P. was isolated A. The purified fraction secondary metabolites characterized by combining TLC, GC-MS, 1H NMR 13C analyses. TLC identified as milbemycin. pure did not show any antioxidant...
Abstract Objective The present study aimed at isolating proteolytic bacteria from dairy effluent sludge, designing the process parameters for enhanced production of protease and determination its fibrinolytic potential. Methods sludge was processed according to microbiological criteria isolation bacteria. All isolates were screened their ability isolate showing highest proteolysis selected further studies. Effects various media components like carbon nitrogen supplementation, temperature, pH...
The present investigation highlights the process parameters influencing submerged fermentation of chitinase by Bacillus pumilus JUBCH08, purification and characterization enzyme determination antagonistic activity bacterium against Fusarium oxysporum. Medium supplemented with 0.5 % chitin peptone, at initial pH 8.0, when incubated 35 °C for 72 h favored highest production. was purified 25.1-fold to homogeneity. found be thermostable alkali-tolerant maximum 8.0 70 1 h. molecular weight 64 kDa...
Abstract The Compact Muon Solenoid collaboration is designing a new high-granularity endcap calorimeter, HGCAL, to be installed later this decade. As part of development work, prototype system was built, with an electromagnetic section consisting 14 double-sided structures, providing 28 sampling layers. Each layer has hexagonal module, where multipad large-area silicon sensor glued between electronics circuit board and metal baseplate. pads approximately 1.1 cm 2 are wire-bonded the readout...

Benzo[a]pyrene, a high molecular weight polycyclic aromatic hydrocarbon possesses carcinogenic, teratogenic, and mutagenic properties. The present study focuses on benzo[a]pyrene degradation by Pleurotus ostreatus PO-3, characterization identification of metabolites produced the extent in presence axenic culture P. PO-3 defined co-cultures basidiomycete with bacteria non-basidiomycete fungi. Thin-layer chromatography revealed that transformed to polar metabolites. Following degradation,...
The study aimed at determining the in vitro antimicrobial activity of alkaliphilic and halotolerant actinomycetes isolated from a mangrove ecosystem identification potent strain. Twenty five isolates were sediment samples Valapattanam swamp Kerala, India. Antimicrobial four selected actinomycete was determined against bacterial fungal pathogens nosocomial origin by agar well diffusion method. Molecular characterization isolate performed 16S rDNA sequencing. Isolate no I-1 significantly...
The present study was aimed at optimization, production and partial purification of lipases from Pseudomonas aeruginosa, Candida albicans Aspergillus flavus. Various nutritional physical parameters affecting lipase such as carbon nitrogen supplements, pH, temperature, agitation speed incubation time were studied.

Aflatoxin B1 (AFB1) produced by Aspergillus flavus is known to have carcinogenic and teratogenic effects on animal health. Accidental feeding of AFB1-contaminated rice straw may be detrimental dairy cattle. White-rot basidiomycetous fungus Pleurotus ostreatus can grow different agronomic wastes synthesizing ligninolytic enzymes. These extracellular enzymes are capable degrading many environmentally hazardous compounds including AFB1. The present study examines the ability strains P. degrade...
Filamentous fungi are efficient producers of lipases.
