Fungal contamination and mycotoxins in aquafeed and tissues of aquaculture fishes and their biological control
( Elsevier B.V. , 2023 , Article)The presence of mycotoxins in food and feed is a significant issue, especially in fish farming where it can negatively impact farmed fish species. In this study, samples of aquaculture feed and fishes tissues were collected ... -
Use of phytochemicals to control the Mycotoxicosis in poultry
( Taylor and Francis Ltd. , 2024 , Article)SUMMARY: Mycotoxins are the secondary fungal metabolites produced by various toxigenic fungal species and are found in several feedstuffs, particularly in plants during pre- and post-harvesting conditions, like processing, ... -
Investigation of novel bacteriocin producers of Bacillus thuringiensis and partial characterization of two new bacteriocins: Thuricin 466 and thuricin 4Q7
( Elsevier Ltd , 2024 , Article)This study assessed the bacteriocin-producing capability of 140 strains of Bacillus thuringiensis isolated from Qatar. Numerous Bt strains exhibited strong antibacterial activity against both the foodborne pathogen B. ... -
Endophytes and Halophytes to Remediate Industrial Wastewater and Saline Soils: Perspectives from Qatar
( MDPI , 2022 , Article Review)Many halophytes are considered to be salt hyperaccumulators, adopting ion extrusion and inclusion mechanisms. Such plants, with high aboveground biomass, may play crucial roles in saline habitats, including soil desalination ... -
Prevalence of toxigenic fungi and mycotoxins in Arabic coffee (Coffea arabica): Protective role of traditional coffee roasting, brewing and bacterial volatiles
( Public Library of Science , 2021 , Article)Fungal infection and synthesis of mycotoxins in coffee leads to significant economic losses. This study aimed to investigate the prevalence of toxigenic fungi, their metabolites, and the effect of traditional roasting and ... -
Hypolithic cyanobacteria colonization of quartz at South Desert
( Science Publications , 2014 , Article)Hypolithic microbial communities (found underneath rocks) were encountered in the southern desert of Qatar where quartz rocks are ubiquitous and are a substrate for hypoliths. These hypoliths thrive where extreme temperature, ... -
Engineering of mutants of Anabaena PCC7120 (cyanobacterium) constructed by DNA-plasmid transfer and UV-radiation resistant to the herbicide Diuron capable of ammonia production
( Elfos Scientiae , Cuba , 2004 , Article)Ten mutants of Anabaena PCC7120 were successfully constructed to express two genetic traits, ammonia production and the resistance to the Diuron herbicide, using transposon induced mutagenesis and UV-radiation. The ranges ... -
A complete sequence of the 16S rRNA gene of a novel Streptomyces coelicolor (AB588124) (QU66c-2002) isolated from the soil of Qatar
( Asian Network for Scientific Information , 2011 , Article)The aim of this study was to determine the sequence of the 16S rRNA gene and thus to conduct the phylogenic position of the naturally occurring wild type strain of Streptomyces QU66C. Here we show conclusively the full ... -
Halophytes and associated properties of natural soils in the Doha area, Qatar
( Michigan State University Press , 2007 , Conference)Plant life and the life they support are being eliminated and cannot cope with the construction activities in Doha City. One of the most important reasons behind this study is the fast rate at which many habitats are ... -
Perspectives of future water sources in Qatar by phytoremediation: biodiversity at ponds and modern approach
( Bellwether Publishing, Ltd. , 2021 , Article Review)Anthropogenic and industrial wastewater (IWW) could be an additional future source of water to support the needs of the people of the State of Qatar. New lagoons have been built using modern technologies to optimize water ... -
Isolation, biochemical and molecular characterization of 2-chlorophenol-degrading Bacillus isolates
( Academic Journals , 2007 , Article)Pure cultures of 2-chlorophenol degrading bacteria were isolated from a natural enrichment that may be adapted to chlorophenols in the industrial zone at Umm-Saied city (Qatar). The bacteria were identified by 16S rDNA ... -
Phytoremediation of polluted soils and waters by native Qatari plants: Future perspectives
( Elsevier , 2020 , Article Review)Because pollution is predicted to worsen and sources of quality water for agriculture and other human activities are limited, many countries have been motivated to seek novel water sources. Qatar relies on groundwater and ... -
Investigation of heat-resistant antifungal agents from Bacillus amyloliquefaciens and Bacillus subtilis for biocontrol of mycotoxigenic fungi
( Elsevier , 2024 , Article)Fungal infections of food and feed with toxigenic strains results in the accumulation of harmful metabolites. In this study, the antifungal activity of two indigenous bacterial strains Bacillus amyloliquefaciens and Bacillus ... -
Population dynamics and predatory impact of the alien jellyfish Aurelia solida (Cnidaria, Scyphozoa) in the Bizerte Lagoon (southwestern Mediterranean Sea)
( Hellenic Centre for Marine Research , 2020 , Article)Understanding the life cycle strategies and predatory impact of alien jellyfish species is critical to mitigate the impact that these organisms may have on local populations, biodiversity, and ultimately on the functioning ... -
Phytoplankton size changes and diversity loss in the southwestern Mediterranean Sea in relation to long-term hydrographic variability
( Academic Press , 2020 , Article)Structural changes in plankton primary producers have large implications for food web dynamics, energy fluxes and the vertical export of biogenic particulate carbon. Here we examine phytoplankton data spanning the period ... -
A novel index based on planktonic copepod reproductive traits as a tool for marine ecotoxicology studies
