Seropositivity of dengue cases at a tertiary care centre in Chhindwara, Madhya Pradesh: A three year trend.

Background: During the recent decades, dengue virus infection has been emerged as a major public health problem. Dengue is one of the important mosquito borne infections causing high mortality and morbidity of humans. : This study was carried out from October 2018 to December 2020.

Exo-inulinase production from Aspergillus fumigatus NFCCI 2426: purification, characterization, and immobilization for continuous fructose production.

Aspergillus fumigatus was found to produce thermostable exo-inulinase (EC 3.8.1.

Prebiotic mannooligosaccharides: Synthesis, characterization and bioactive properties.

Functional oligosaccharides are non-digestible food ingredients that confer numerous health benefits. Among these, mannooligosaccharides (MOS) are emerging prebiotics that have characteristic potential bio-active properties. Microbial mannanases can be used to break down mannan rich agro-residues to yield MOS.

Production of mannooligosaccharides from various mannans and evaluation of their prebiotic potential.

Aspergillus quadrilineatus endo-β-mannanase effectively degraded konjac glucomannan (66.09% w/v), copra meal (38.99% w/v) and locust bean galactomannan (20.

Immobilization of Aspergillus quadrilineatus RSNK-1 multi-enzymatic system for fruit juice treatment and mannooligosaccharide generation.

Aspergillus quadrilineatus RSNK-1 produced a multi-enzymatic system containing (U/gds) β-mannanase (1021), endo-xylanase (1 9 1), α-galactosidase (3.42), β-xylosidase (0.07) and β-glucosidase (0.

Production optimization and characterization of mannooligosaccharide generating β-mannanase from Aspergillus oryzae.

A multi-tolerant β-mannanase (ManAo) was produced by Aspergillus oryzae on copra meal, a low-cost agro waste. Under statistically optimized conditions, 4.3-fold increase in β-mannanase production (434 U/gds) was obtained.

Catalytic characteristics and application of l-asparaginase immobilized on aluminum oxide pellets.

l-asparaginase from Escherichia coli (l-ASNase) was covalently immobilized on aluminum oxide pellets (AlOPs) using a cross-linking agent, glutaraldehyde. Maximum immobilization yield (85.0%) was obtained after optimizing immobilization parameters using response surface methodology (RSM).

Characterization of cellulase from Aspergillus tubingensis NKBP-55 for generation of fermentable sugars from agricultural residues.

The aim of this work was to characterize cellulase from Aspergillus tubingensis NKBP-55 for generation of fermentable sugars from agricultural residues. The strain produced high titres of cellulase (750 U/gds) on copra meal in solid state fermentation (SSF). The enzyme preparation also showed hemicellulolytic activities (U/gds) viz.
