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 ...
Alginate-mediated synthesis of hetero-shaped silver nanoparticles and their hydrogen peroxide sensing ability
(
Qatar University Press
, 2020 , Poster)
Silver nanoparticles have been the focus of extensive research for many decades due to their unique physical, chemical and electrical properties. Introducing new environmentally benign methods for the synthesis of silver ...
Assessment of Anti-proliferative and Anti-bacterial Activity of a Desert Microalgal Strain Desmodesmus sp.
(
Qatar University Press
, 2020 , Poster)
Microalgae are believed to be a promising sources of different high value products (HVP). HVP are metabolites which are produced during the growth of microalgae and their production is triggered by the physiochemical growth ...
Catalytic decomposition of ethanol over bimetallic NiCo catalysts for carbon nanotube synthesis
(
Qatar University Press
, 2020 , Poster)
In this work we investigate the use of NiCo bimetal/oxide as catalyst for hydrogen production from ethanol, with a focus on the deactivation pattern and the nature of the observed carbon deposition [1, 2]. It is well known ...
Novel approach to study the diversity of soil microbial communities in Qatar
(
Qatar University Press
, 2020 , Poster)
A broad diversity of microorganisms can be found in soil, where they are essential for nutrient cycling and energy transfer. Recent high-throughput sequencing methods have greatly advanced our knowledge about how soil, ...
Biological Control of Mycotoxigenic Fungi and Ochratoxin A by The In-Vitro Application of a Qatari Burkholderia cepacia Strain (QBC03)
(
Qatar University Press
, 2020 , Poster)
Mycotoxins are secondary metabolites synthesized by mycotoxigenic fungi belonging mainly to three major fungal genera that are Aspergillus, Fusarium and Penicillium. The latter mycotoxigenic fungi contaminate plants and ...
Highly active bifunctional LaMO3 (M=Cr, Mn, Fe, Co, Ni) perovskites for oxygen reduction and oxygen evolution reaction in alkaline media
(
Qatar University Press
, 2020 , Poster)
Lanthanum based electrocatalytically active perovskites, LaMO3 (M=Cr, Mn, Fe, Co, Ni), were synthesized using a single step solution combustion synthesis technique. The perovskites showed exceptional performance for oxygen ...
The use of Principle Component Analysis and MALDI-TOF MS for the differentiation of mineral forming Virgibacillus and Bacillus species isolated from Sabkhas.
(
Qatar University Press
, 2020 , Poster)
Occurrence of mineral forming and other bacteria in mats is well demonstrated. However, their high diversity shown by ribotyping was not explained, although could explain the diversity of formed minerals. Common biomarkers ...
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 ...
Assessment of Tarmat contamination and its chemical characterization along the west coast of Qatar, Arabian Gulf
(
Qatar University Press
, 2020 , Poster)
Tarmat/Oil residue (hereafter 'TM') is one of the serious threats to the marine ecosystem due to their toxicity, persistence and bioaccumulation problems. To assess the level of TM contamination and to determine the primary ...
