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 ...
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 ...
Transcriptional and post-transcriptional control of adipocyte differentiation by Jumonji domain-containing protein 6
(
Oxford University Press
, 2015 , Article)
Jumonji domain-containing protein 6 (JMJD6) is a nuclear protein involved in histone modification, transcription and RNA processing. Although JMJD6 is crucial for tissue development, the link between its molecular functions ...
Born small, die young: Intrinsic, size-selective mortality in marine larval fish
(
Nature Publishing Group
, 2015 , Article)
Mortality during the early stages is a major cause of the natural variations in the size and recruitment strength of marine fish populations. In this study, the relation between the size-at-hatch and early survival was ...
Impacts of urbanization on the distribution of heavy metals in soils along the Huangpu River, the drinking water source for Shanghai
(
Springer Berlin Heidelberg
, 2015 , Article)
We investigated the horizontal and vertical distribution of heavy metals (Hg, Pb, Zn, Cu, Cd, As, Ni, and Cr) in soils in the water source protection zone for Shanghai to study the origins of these metals, their connections ...
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 ...
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 ...
Biological Activities and Chemical Composition of Methanolic Extracts of Selected Autochthonous Microalgae Strains from the Red Sea
(
MDPI AG
, 2015 , Article)
Four lipid-rich microalgal species from the Red Sea belonging to three different genera (Nannochloris, Picochlorum and Desmochloris), previously isolated as novel biodiesel feedstocks, were bioprospected for high-value, ...
Opposing calcium-dependent signalling pathways control skeletal muscle differentiation by regulating a chromatin remodelling enzyme
(
Nature Publishing Group
, 2015 , Article)
Calcium signalling is important for differentiation-dependent gene expression, but is also involved in other cellular functions. Therefore, mechanisms must exist to distinguish calcium signalling relevant to differentiation. ...
Community structure and activity of a highly dynamic and nutrient-limited hypersaline microbial mat in Um Alhool Sabkha, Qatar
(
Public Library of Science
, 2014 , Article)
The Um Alhool area in Qatar is a dynamic evaporative ecosystem that receives seawater from below as it is surrounded by sand dunes. We investigated the chemical composition, the microbial activity and biodiversity of the ...
