Evidence of two mechanisms involved in Bacillus thuringiensis israelensis decreased toxicity against mosquito larvae: Genome dynamic and toxins stability
(
Elsevier GmbH
, 2015 , Article)
Biopesticides based on Bacillus thuringiensis israelensis are the most used and most successful around the world. This bacterium is characterized by a dynamic genome able to win or lose genetic materials which leads to a ...
Application of statistical experimental design for optimisation of bioinsecticides production by sporeless Bacillus thuringiensis strain on cheap medium
(
Sociedade Brasileira de Microbiologia - SBM
, 2014 , Article)
In order to overproduce bioinsecticides production by a sporeless Bacillus thuringiensis strain, an optimal composition of a cheap medium was defined using a response surface methodology. In a first step, a Plackett-Burman ...
Overcome of carbon catabolite repression of bioinsecticides production by sporeless Bacillus thuringiensis through adequate fermentation technology
(
Hindawi Publishing Corporation
, 2014 , Article)
The overcoming of catabolite repression, in bioinsecticides production by sporeless Bacillus thuringiensisstrain S22 was investigated
into fully controlled 3 L fermenter, using glucose based medium. When applying adequate ...
Identification of phenolic compounds by HPLC/MS and in vitro evaluation of the antioxidant and antimicrobial activities of Ceratonia siliqua leaves extracts
(
Academic Jounals
, 2015 , Article)
Ceratonia siliqua is a typical plant of the Mediterranean area, which is mainly used as animal and human food and in folk medicine for treating some diseases such as antidiarrheal and diuretic. The present study was planned ...
Biocontrol activity of four non- and low-fermenting yeast strains against Aspergillus carbonarius and their ability to remove ochratoxin A from grape juice
(
Elsevier
, 2014 , Article)
Aspergillus spp. infection of grape may lead to ochratoxin A (OTA) contamination in processed beverages such as wine and grape juice. The aim of the current study was to evaluate the biocontrol potential of two non-fermenting ...
Evidencing the diversity and needs of adjustment of the nutritional requirements for hydrocarbon-degrading activity of: Pseudomonas aeruginosa adapted to harsh conditions using 2<sup>n</sup> full factorial design
(
Royal Society of Chemistry
, 2017 , Article)
To overcome the partial or complete failure of oil hydrocarbon bioremediation due to weathering processes, occurring in most oil producing and spilling areas, nutritional requirements of the most widely used bacterium, ...
Isolation of the Bacillus thuringiensis plasmid carrying Bacthuricin F4 coding genes and evidence of its conjugative transfer
(
The Journal of Infection in Developing Countries
, 2014 , Article)
INTRODUCTION:
Conjugation is an excellent natural mode of DNA transfer in vivo between bacteria, particularly when these conjugative elements carry technological traits such as bacteriocin encoding genes. In the present ...
Considering the Specific Impact of Harsh Conditions and Oil Weathering on Diversity, Adaptation, and Activity of Hydrocarbon-Degrading Bacteria in Strategies of Bioremediation of Harsh Oily-Polluted Soils
(
Hindawi Publishing Corporation
, 2017 , Article)
Weathering processes change properties and composition of spilled oil, representing the main reason of failure of bioaugmentation strategies. Our purpose was to investigate the metabolic adaptation of hydrocarbon-degrading ...
