(
Elsevier
, 2020 , Article)
© 2020 Bacillus thuringiensis (Bt) is a Gram-positive soil bacterium that has been recognized as an effective bioinsecticide active against plant, animal and human pathogenic and disease vector insects. During its sporulation ...
Investigation of Bacillus Thuringiensis Plasmid Instability and its Effect on the Synthesis of Crystals
(
Qatar University Press
, 2020 , Poster)
In order to explore plasmid instability in Bt, four Bt strains belonging to two Bt subspecies were cultured at 42°C for 9 days. HD1 and QBT376 belong to subspecies kurstaki, while H14 and QBT218 belong to subspecies ...
Monitoring the presence and investigation of toxigenic fungi and mycotoxins in poultry feed and its products
(
Qatar University Press
, 2020 , Poster)
Contaminating poultry feed and their products with mycotoxins produced by fungi may cause many health effects on animals and human if they were at high concentrations. Therefore, it is imperative to regularly monitor the ...
Characterization of the Extracellular Polymeric Substances (EPS) of Virgibacillus strains capable of mediating the formation of high Mg-calcite and protodolomite
(
Qatar University Press
, 2020 , Poster)
The origin of dolomite -a common carbonate mineral- is the subject of an ongoing debate. It has been proposed that extracellular polymeric substances (EPS) excreted by microbes contain specific organic molecules that ...
