In this study, 15 bacterial endophytes linked with the leaves of native medicinal plant Pulicaria incisa were isolated and identified as Agrobacterium fabrum, Acinetobacter radioresistant, Brevibacillus brevis, Bacillus cereus, subtilis, Paenibacillus barengoltzii, Burkholderia cepacia. These isolates exhibited variant tolerances to salt stress showed high efficacy in indole-3-acetic acid (IAA) production absence/presence tryptophan. The maximum productivity IAA was recorded for B. cereus...
Herein, bacterial isolate HIS7 was obtained from contaminated soil and exhibited high efficacy to degrade pyrethroid insecticide cypermethrin. The identified as Lysinibacillus cresolivuorans based on its morphology physiology characteristics well sequencing of 16S rRNA. biodegradation percentages 2500 ppm cypermethrin increased 57.7% 86.9% after optimizing the environmental factors at incubation condition (static), period (8-days), temperature (35 °C), pH (7), inoculum volume (3%), addition...
Effective lactic acid (LA) production from lignocellulosic biomass materials is challenged by several limitations related to pentose sugar utilization, inhibitory compounds, and/or fermentation conditions. In this study, a newly isolated Bacillus coagulans strain Azu-10 was obtained and showed homofermentative LA xylose with optimal conditions at 50 °C pH 7.0. Growth of LA-fermentation efficiency were evaluated in the presence various lignocellulose-derived inhibitors (furans, carboxylic...
Toluene and other monoaromatic compounds are released into the environment particularly saline habitats due to inappropriate disposal methods of petroleum products. Studying bio-removal strategy is required clean up these hazardous hydrocarbons that threaten all ecosystem life using halophilic bacteria with higher biodegradation efficiency as a sole carbon energy source. Therefore, sixteen pure bacterial isolates were obtained from soil Wadi An Natrun, Egypt, which have ability degrade...
Bioremediation for wastewater using microbes that can detoxify the harmful effects of Cr-VI is concerned. Ninety-two isolates were collected from tannery effluents and screened based on their abilities to remediate hexavalent chromium LB agar media supplemented by K2Cr2O7 as a source Cr-VI. Out total isolates, 44 grow at 200 ppm CR-VI, while 7, 6, 21, 11, 3 showed growth concentrations 400, 600, 800, 1000, 1200 Cr-VI, respectively. Furthermore, determination reduction efficiency was...
Searching for an alternative disinfection and sanitization strategy to control prevent the contamination diseases caused by microbial pathogens represents one of critical challenges all world governments.So that antimicrobial efficiency ozone gas as a terminal disinfectant was estimated at relatively small level (1.2 mg/l/h) using unit generated local assembled faculty science against six reference strains including Staphylococcus aureus (ATCC 6538), Bacillus subtilis 9372), spizizenii...
