Characterization of the extracellular polymeric substances (EPS) of Virgibacillus strains capable of mediating the formation of high Mg-calcite and protodolomite
(
Elsevier B.V.
, 2019 , Article)
The origin of dolomite –a common mineral in the geological record– is the subject of an ongoing debate. Among different hypotheses, it has been proposed that extracellular polymeric substances (EPS) excreted by microbes ...
Assessment of the environmental health of an ecologically sensitive, semi-enclosed, basin - A water quality modelling approach.
(
Elsevier
, 2018 , Article)
Semi-enclosed basins are environmentally dynamic and some of the most anthropogenically affected components of the coastal realm. They can reflect various environmental impacts, thus qualifying as natural laboratories to ...
Field and laboratory investigation of tarmat deposits found on Ras Rakan Island and northern beaches of Qatar
(
Elsevier
, 2020 , Article)
© 2018 Elsevier B.V. Beaches of Ras Rakan Island, located off the northern tip of Qatar, are extensively contaminated by highly weathered tarmat deposits. The focus of this study is to determine the possible source of the ...
Associated effects of storage and mechanical pre-treatments of microalgae biomass on biomethane yields in anaerobic digestion
(
Elsevier
, 2016 , Article)
The pre-treatment of microalgae cell walls is known to be a key factor to enhance methane (CH4) yields during anaerobic digestion. This study investigated the combined effects of two different biomass storage methods and ...
Macrobenthos in the central Arabian Gulf: a reflection of climate extremes and variability
(
Springer International Publishing
, 2016 , Article)
The arid subtropical ecosystem of the central Arabian Gulf was used to explore the combined effects of low primary productivity, high salinities, and variable temperatures on the composition and structure of benthic ...
Hydroacoustics to examine fish association with shallow offshore habitats in the Arabian Gulf
(
Elsevier B.V.
, 2018 , Article)
In order to implement spatial fisheries management in the Arabian Gulf, a better understanding of the distribution of fish in relation to benthic habitats is required. To facilitate this, hydroacoustic fish surveys were ...

Concentrations of 25 heavy metals (Ag, Al, As, Ba, Be, Ca, Cd, Co, Cr, Cu, Fe, K, Li, Mg, Mn, Mo, Na, Ni, Pb, Sb, Se, Sr, V, Zn and Hg) in surface sediments along the Doha Bay from 10 transects each with five stations were ...
Microbial community composition and dolomite formation in the hypersaline microbial mats of the Khor Al-Adaid sabkhas, Qatar
(
Springer Tokyo
, 2019 , Article)
The Khor Al-Adaid sabkha in Qatar is among the rare extreme environments on Earth where it is possible to study the formation of dolomite-a carbonate mineral whose origin remains unclear and has been hypothetically linked ...
Acutodesmus obliquus as a benchmark strain for evaluating methane production from microalgae: Influence of different storage and pretreatment methods on biogas yield
(
Elsevier
, 2015 , Article)
Acutodesmus obliquus (SAG 276-1), a microalga with a resistant cell wall, was chosen as a benchmark strain for testing the effect of storage and pretreatment methods on methane yields during anaerobic digestion. A. obliquus ...
