Characterization and assessment of process water from oil and gas production: A case study of process wastewater in Qatar
(
Elsevier
, 2022 , Article)
This study characterized and assessed three different process water (PWWs) (S-1, S-2, and S-3) from oil and gas production in Qatar. The wastewater generated in various processing stages contains many harmful components ...
Evidencing the role of carbonic anhydrase in the formation of carbonate minerals by bacterial strains isolated from extreme environments in Qatar
(
Elsevier
, 2022 , Article)
Calcium carbonate, one of the most abundant minerals in the geological records is considered as primary source of the carbon reservoir. The role of microorganisms in the biotic precipitation of calcium carbonate has been ...
Interaction between indigenous hydrocarbon-degrading bacteria in reconstituted mixtures for remediation of weathered oil in soil
(
Elsevier
, 2022 , Article)
It has been demonstrated that biostimulation is necessary to investigate the interactions between indigenous bacteria and establish an approach for the bioremediation of soils contaminated with weathered oil. This was ...
The use of principle component analysis and MALDI-TOF MS for the differentiation of mineral forming: Virgibacillus and Bacillus species isolated from sabkhas
(
Royal Society of Chemistry
, 2020 , Article)
Occurrence of mineral forming and other bacteria in mats is well demonstrated. However, their high diversity shown by ribotyping has not been explained, although it could explain the diversity of formed minerals. Common ...
Valorization of palm tree (Phoenix dactylifera L.) leaves from harsh weather climate by silage using endogenous lactic acid bacteria, and application of MALDI-TOF MS for study of populations dynamics
(
Elsevier
, 2023 , Article)
Preservation of green palm leaves by silage preserves them as green feed in addition to the added value of probiotics and prebiotics. In this work, the characterization of fresh palm tree leaves was performed. The isolation ...
Algal-algal bioflocculation enhances the recovery efficiency of Picochlorum sp. QUCCCM130 with low auto-settling capacity
(
Elsevier B.V.
, 2023 , Article)
Large-scale production of microalgal biomass is still considered non-viable due to the high cost and energy required for harvesting. A fast, cost-effective, and successful harvesting technique has become widely sought after ...
