Bioconversion of agro-industrial wastes for the production of fibrinolytic enzyme from Bacillus halodurans IND18: Purification and biochemical characterization

Electron. j. biotechnol; 19 (2), 2016
Background: Agro-wastes were used for the production of fibrinolytic enzyme in solid-state fermentation. The process parameters were optimized to enhance the production of fibrinolytic enzyme from Bacillus halodurans IND18 by statistical approach. The fibrinolytic enzyme was purified, and the properties ...

Enhanced production and organic solvent stability of a protease fromBrevibacillus laterosporus strain PAP04

Braz. j. med. biol. res; 49 (4), 2016
A bacterial strain (PAP04) isolated from cattle farm soil was shown to produce an extracellular, solvent-stable protease. Sequence analysis using 16S rRNA showed that this strain was highly homologous (99%) to Brevibacillus laterosporus. Growth conditions that optimize protease production in this strain ...

Anti-Trimeresurus albolabris venom IgY antibodies: preparation, purification and neutralization efficacy

Background Snakebite incidence in southwestern China is mainly attributed to one of the several venomous snakes found in the country, the white-lipped green pit viper Trimeresurus albolabris. Since antivenom produced from horses may cause numerous clinical side effects, the present study was conducted a...

Molecular characterization of a novel thermostable laccase PPLCC2 from the brown rot fungus Postia placenta MAD-698-R

Electron. j. biotechnol; 18 (6), 2015
Background Laccase has been considered important for the degradation of lignocellulose by wood rot fungi. The properties and functions of laccase in white rot fungi have been investigated extensively, but those from brown rot fungi remain largely unknown. In this paper, a laccase isoform Pplcc2 from the ...

Electroforesis horizontal en geles de poliacrilamida en la detección y tipificación del virus de papiloma humano
Horizontal electrophoresis in polyacrylamide gels in the detection and typing of human papillomavirus

OBJETIVO: estandarizar el uso de electroforesis horizontal en poliacrilamida como un método rápido de fácil implementación y de alta sensibilidad para la detección y tipificación del virus del papiloma humano por reacción en cadena de la polimerasa-polimorfismos de longitud de fragmentos de restri...

Proteinase activity in latex of three plants of the family Euphorbiaceae

Braz. j. pharm. sci; 50 (3), 2014
In the family of Euphorbiaceae, the genera Euphorbia and Sapium are known to contain essentially latex-bearing species. In the present study, the latex of Euphorbia selloi (Klotzsch & Garcke) Boiss., Euphorbia papillosa A.St.-Hil., and Sapium glandulosum (L.) Morong, plants native from Brazil, were e...

Proteomic analysis of the regenerating liver following 2/3 partial hepatectomy in rats

Biol. Res; 47 (), 2014
BACKGROUND: Liver regeneration (LR) after 2/3 partial hepatectomy (PH) is one of the most studied models of cell, organ, and tissue regeneration. Although the transcriptional profile analysis of regenerating liver has been carried out by many reserachers, the dynamic protein expression profile during LR ...

Stress tolerant virulent strains of Cronobacter sakazakii from food

Biol. Res; 47 (), 2014
BACKGROUND: Cronobacter sakazakii is considered as an emerging foodborne pathogen. The aim of this study was to isolate and characterize virulent strains of Cronobacter sakazakii from food samples of Bangladesh. RESULT: Six (6) Cronobacter sakazakii was isolated and identified from 54 food samples on the...

Production of antibody fragment (Fab) throughout Escherichia coli fed-batch fermentation process: Changes in titre, location and form of product

Electron. j. biotechnol; 16 (3), 2013
Background: Recombinant proteins, including antibodies and antibody fragments, often contain disulfide bond bridges that are necessary for their folding, stability and function. Production of disulfide-bond-containing proteins in the periplasm of Escherichia coli has been very useful, due to unique chara...

Comparative electrophoretic profile of proteins and esterases in healthy silkworm larvae (Bombyx mori Lineu, 1758) and infected with nucleopolyhedrovirus

Acta sci., Biol. sci; 35 (1), 2013
Total proteins and esterases from silk gland extracts of Bombyx mori silkworm were characterized and compared with electrophoretic profiles of prepared extracts with silkworm glands infected with nucleopolyhedrovirus (BmNPV). SDS-PAGE (7%) gels was used for the total proteins, and 10% native PAGE for est...
