Minimizing wind erosion using microbial induced carbonate precipitation
(
American Society of Civil Engineers (ASCE)
, 2019 , Conference Paper)
This research focuses on investigating the effectiveness of microbial-induced carbonate precipitation (MICP) to reduce the potential for wind erosion. This paper summarizes the results of preliminary wind tunnel experiments. ...
Isolation, screening and activity of hydrocarbon-degrading bacteria from harsh soils
(
Avestia Publishing
, 2016 , Conference Paper)
The study of microbial communities in relation to their ecology, interaction, and genetics must be covered in Qatar with special soil, weather and water. Microorganisms of an environment never having been exposed to such ...
Statistical Analysis of Cultural Parameters Influencing Delta-Endotoxins and Proteases Productions by Bacillus thuringiensis kurstaki
(
Springer Verlag
, 2016 , Article)
Bacillus thuringiensis is a spore-forming bacterium that produces delta-endotoxins, which are toxic to lepidopterans, dipterans and coleopterans. Concomitantly with production of delta-endotoxins, B. thuringiensis produces ...
Improvement of Bacillus thuringiensis bioinsecticide production by sporeless and sporulating strains using response surface methodology
(
Elsevier B.V.
, 2011 , Article)
Statistical experimental designs, involving a Plackett-Burman design followed by a rotatable central composite design were used to optimize the culture medium constituents for Bacillus thuringiensis bioinsecticide production. ...
Combinatorial effect of mutagenesis and medium component optimization on Bacillus amyloliquefaciens antifungal activity and efficacy in eradicating Botrytis cinerea
(
Elsevier GmbH
, 2017 , Article)
This work is directed towards Bacillus amyloliquefaciens strain BLB371 metabolite production for biocontrol of fungal phytopathogens. In order to maximise antifungal metabolite production by this strain, two approaches ...
A MALDI-TOF study of bio-remediation in highly weathered oil contaminated soils
(
Elsevier
, 2018 , Article)
We have shown that Bacillus cereus is dominating the bacterial population at three polluted oil-industry sites
where weather and soil conditions are extreme in terms of temperature, UV-radiation and salinity. A minor ...
Potential of Photorhabdus temperata K122 bioinsecticide in protecting wheat flour against Ephestia kuehniella
(
Elsevier Ltd
, 2013 , Article)
The present study reports investigations on the insecticidal activity of the entomopathogenic bacterium Photorhabdus temperata K122 against the Mediterranean flour moth Ephestia kuehniella. Cultured in the optimized medium, ...
Involvement of oxidative stress and growth at high cell density in the viable but nonculturable state of Photorhabdus temperata ssp. temperata strain K122
(
Elsevier Ltd
, 2010 , Article)
Photorhabdus temperata ssp. temperata strain K122 represents a promising source of bioinsecticide. When cultured in an optimized medium, P. temperata exhibited restricted survival in terms of colony-forming ability on solid ...
