Effect of nutrients deficiency on biofilm formation and single cell protein production with a purple non-sulphur bacteria enriched culture.

Purple non-sulphur bacteria (PNSB) are of interest for biorefinery applications to create biomolecules, but their production cost is expensive due to substrate and biomass separation costs. This research has utilized fuel synthesis wastewater (FSW) as a low-cost carbon-rich substrate to produce single-cell protein (SCP) and examines PNSB biofilm formation using this substrate to achieve a more efficient biomass-liquid separation. In this study, PNSB were grown in Ca, Mg, S, P, and N-deficient media using green shade as biofilm support material.

Isolation and Identification of Organics-Degrading Bacteria From Gas-to-Liquid Process Water.

The gas-to-liquid (GTL) process generates considerable amounts of wastewater that are highly acidic and characterized by its high chemical oxygen demand (COD) content, due to the presence of several organic pollutants, such as alcohols, ketones, aldehydes, and fatty acids. The presence of these organics in the process water may lead to adverse effect on the environment and aquatic life. Thus, it is necessary to reduce the COD content of GTL process water to an acceptable limit before discharging or reusing the treated water.

Dataset comparing the growth of fodder crops and soil structure dynamics in an industrial biosludge amended arid soil.

The dataset in this work compares the response of two fodder crops, alfalfa () and buffel grass (), to industrial biosludge amendment of an arid soil in the State of Qatar. It also evaluates the response of soil structure parameters in the biosludge-amended soils containing the different fodder crops. The dataset relates to our previously published works detailed subsequently.

Recycling industrial biosludge for buffel grass production in Qatar: Impact on soil, leachate and plant characteristics.

The agricultural industry in Qatar is highly dependent on using soil enhancing materials due to challenging soil and climatic conditions. Hence, this work investigated the potential of industrial biosludge from the wastewater treatment plant (WWTP) of a Gas-to-Liquids (GTL) plant to enhance an arid soil compared to fertilizer and compost. A fodder crop, buffel grass (Cenchrus ciliaris), was grown in semi-controlled pots containing a typical Qatari agricultural soil and admixtures over a 12-month period.

Dataset on the influence of gas-to-liquid biosludge on arid soil properties and growth performance of alfalfa.

The dataset presented here is related to our research article entitled "Effect of gas-to-liquid biosludge on soil properties and alfalfa yields in an arid soil" [1]. It relates to selected performance parameters of alfalfa grown in an arid soil amended with five different (0.75-12%) gas-to-liquid biosludge contents, and selected properties of the soil determined using several material characterization techniques.
