Optimization of phytase production in solid state fermentation by different fungi

The present study was conducted to explore the potential fungal isolates for maximum production of phytase by optimizing solid substrate preference and growth parameters (pH, temperature, fermentation time) of solid state fermentation (SSF). It has been inferred from the results that all the tested fungi (Aspergillus niger, Aspergillus flavus, Aspergillus versicolor, Aspergillus nidulans, Cladosporium cladosporioides,...

Thermoanaerobacter spp. recovered from hot produced water from the Thar Jath oil-field in South Sudan

Two bacterial isolates, designated S1.1 and S3.1, were recovered from oil-well produced water extracted from a deep and hot oil-well in the Thar Jath oil-field in South Sudan, and characterized. Based on their 16S rRNA gene sequences and phenotypic properties, the isolates were identified as members of the genus Thermoanaerobacter, possibly representing novel species. Both strains are strict anaerobes, grow optimally at...

Detection of acute toxoplasmosis in rural women in Sudan using different diagnostic tests

Blood samples from 254 childbearing age women from two villages (EL Nuba and EL Massoudia) were collected after seeking their consent; their written consent form was obtained. Detection of IgM for acute toxoplasmosis was done using two different enzyme-linked immunosorbent assay (ELISA) techniques. Prevalence of IgM was 18.9 and 20.3%; this was obtained by using ELISA IgM in Khartoum for all samples and ELISA IgM in...

In vitro antimicrobial activity of Ruta chalepensis methanol extracts against the cariogenic Streptococcus mutans

Medicinal plants have been used for centuries and have become part of complementary medicine worldwide because of their potential health benefits. Since dental caries is one of the most common oral diseases and is considered a major public health problem, the present study evaluated in vitro antimicrobial potential of methanol extracts of Ruta chalepensis against the major etiologic agent of dental caries, Streptococcus...

Characterization of antimicrobial resistance and related resistance genes in Escherichia coli strains isolated from chickens in China during 2007-2012

In the present study, the prevalence of antimicrobial-resistant chicken Escherichia coli strains and the resistance genes in E. coli was investigated. For this purpose, 1002 chicken E. coli strains isolated from layer and broiler flocks in Shaanxi, Henan and Gansu provinces in China during 2007-2012 were examined. Antimicrobial susceptibility of these E. coli strains against 18 antimicrobials was determined by the...

Time kill-kinetics antibacterial study of Acacia nilotica

In vitro time-kill kinetics antibacterial study of Acacia nilotica was assessed against Pseudomonas aeruginosa, Escherichia coli and Staphylococcus aureus determined by plate count technique and analyzed by percentage and log reduction. All test organisms were susceptible to the aqueous methanolic extract. The minimum inhibitory concentration ranged between 0.5 and 1 mg, while minimum bactericidal concentration ranged...

Bioethanol production from starchy part of tuberous plant (potato) using Saccharomyces cerevisiae MTCC-170

Ethanol is one of the bio-energy sources with high efficiency and low environmental impact. Various raw materials have been used as carbon source for ethanol production. In the present study, one varieties of potato that is, Kufri Bahar (KB) flour was chosen as a carbon source. In order to obtain maximum conversion of starch into fermentable sugar, optimum parameters for the liquefaction were determined as 104 to...

In vitro antibacterial activities of dietary medicinal ethanolic extracts against pathogenic reference strains of animal origin

In vitro antibacterial activities of five extracts from dietary medicinal plants were investigated by agar-well diffusion method (AWD), minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) against 13 foodborne pathogenic bacteria reference strains; four Gram positive bacteria including Staphylococcus aureus (NCINB 50080), Bacillus cereus (NCINB 50014), Citrobacter freundi (ATCC 8090) and...

Mycoplasma gallisepticum in free-range chicken from Northern Tocantins State, Brazil

Mycoplasma gallisepticum is a major problem of the poultry industry worldwide. This infectious disease, which affects animals worldwide, is caused by bacteria. The aim of this study was to determine the prevalence of M. gallisepticum in free-range chickens raised in Araguaína, Tocantins, using rapid plate agglutination test (SAR). Blood samples of 175 free-range chickens from the city of Araguaína,...
