(
Elsevier
, 2013 , Article)
This study was undertaken to determine the antibacterial efficacy of the leaves extracts of Lawsonia inermis in vitro and in vivo, against the phytopathogenic bacteria Pseudomonas savastanoi pv savastanoi IVIA 1628 and ...
Adsorption of ochratoxin A from grape juice by yeast cells immobilised in calcium alginate beads
(
Elsevier
, 2016 , Article)
Grape juice can be easily contaminated with ochratoxin A (OTA), one of the known mycotoxins with the greatest public health significance. Among the different approaches to decontaminate juice from this mycotoxin, microbiological ...
Application of statistical experimental design for optimisation of bioinsecticides production by sporeless Bacillus thuringiensis strain on cheap medium
(2013 , 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 ...
Molecular identification and biocontrol of ochratoxigenic fungi and ochratoxin A in animal feed marketed in the state of Qatar
(
Elsevier Ltd
, 2023 , Article)
Ochratoxin A (OTA) is a toxic fungal metabolite produced by some Aspergillus and Penicillium species. This work was designed to explore the presence of OTA and ochratoxigenic fungi in feed grains marketed in Qatar and their ...
Perfume Guns: Potential of Yeast Volatile Organic Compounds in the Biological Control of Mycotoxin-Producing Fungi
(
MDPI
, 2023 , Other)
Pathogenic fungi in the genera Alternaria, Aspergillus, Botrytis, Fusarium, Geotrichum, Gloeosporium, Monilinia, Mucor, Penicillium, and Rhizopus are the most common cause of pre- and postharvest diseases of fruit, vegetable, ...
Application of scanning electron microscopy and MALDI-TOF MS in the exploration of the parasporal insecticidal crystals of Bacillus thuringiensis strains isolated from Qatar soil
(
Elsevier Ltd
, 2022 , Article)
Bacillus thuringiensis (Bt) plays an important role in health and agriculture due to its insecticidal activities. In this study, six Bt strains isolated from Qatar soil were used to explore their crystals morphologies and ...
Yeast Volatile Organic Compounds Inhibit Ochratoxin Biosynthesis By Aspergillus Carbonarius and a Ochraceus
(
Hamad bin Khalifa University Press (HBKU Press)

Ochratoxin A (OTA) has hepatotoxic, teratogenic, nephrotoxic and carcinogenic effect in mammals and it is classified as a group 2B carcinogen by the World Health Organization. The European Union has set the maximum OTA ...
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 ...
Biocontrol Activities of Bacillus megaterium Volatile Organic Compounds (VOCs) Against Mycotoxigenic Aspergillus, Penicillium and Fusarium fungi
(
Qatar University Press
, 2020 , Poster)
Mycotoxins are secondary metabolites that are produced by toxigenic fungi once the temperature and humidity are appropriate. Mycotoxins are known to have adverse health effects. There are chemical, physical, thermal and ...
Investigation and Biological Control of Toxigenic Fungi and Mycotoxins in Dairy Cattle Feeds
(
Qatar University Press
, 2020 , Poster)
Mycotoxins, the secondary fungal metabolites are important contaminants of food and feed. Among the other contaminants, aflatoxin B1 (AFB1) and OTA are frequently detected in the animal feed product. In the present study, ...
