“…The enhancement of DBT‐BDS using Gordonia alkanivorans strain 1B has been previously reported, applying the agro‐industrial waste sugar beet molasses as a carbon source, recording a growth rate of 0.0795 h −1 and 2‐HBP production of 250 μmol L −1 5 . Total reducing sugars in Jerusalem artichoke juice have been reported to duplicate the BDS efficiency of G. alkanivorans strain 1B 8 . The agro‐industrial waste carob pulp liquor has been also reported as a cost‐effective carbon source for BDS 62 …”

“…Nevertheless, the main challenge in BDS is to enrich a microbial isolate capable of desulfurizing the oil feed without affecting its hydrocarbon skeleton and consequently its calorific value. The main cost in the BDS process is related to the media components, which are essential to enrich the microbial growth and enzymatic activity, to maximize the BDS capacity 5–8 …”

[5][6][7][8] Biodiesel is a feasible alternative and / or complementary transportation fuel. It is biodegradable, renewable, and it offers cleaner combustion with lower greenhouse gas emissions and better lubricity.…”

This study provides a new emphasis for research on the valorization of biowastes into nanocatalyst and biorefineries to be integrated with petroleum bioupgrading and polluted water treatment. The response surface optimized batch transesterification of waste‐frying oil using methanol and sustainable animal bone valorized fluorapatite nanocatalyst (FAP) yielded approximately 97% biodiesel via a pseudo‐second‐order reaction with an efficient rate of 0.48 (mol L−1)−1min−1 and activation energy of 13.11 kJ mol−1. In a pioneering step, by‐products of the starch industry and the biodiesel transesterification process; corn‐steep liquor (CSL 0.2 g L−1) and bioglycerol (6.24 g L−1) as nitrogen and carbon sources, increased the dibenzothiophene biodesulfurization (BDS) efficiency of a novel biodesulfurizing Rhodococcus jialingiae strain HN3 (NCBI Gene Bank Accession No. MN173539) sixfold. Further, upon the application of such bioproducts in a batch BDS process (1/3 petro‐diesel/water) of 96 h; HN3 desulfurized 82.26% of 0.62 wt.% sulfur without affecting the petro‐diesel calorific value. In an attempt to reach zero waste, an auxiliary pioneering step was performed, where the spent waste FAP, after being efficiently used for four successive transesterification cycles, was applied to photo‐remediate 4‐nitrophenol polluted water under UV‐irradiation. Advantageously, the fresh and spent waste FAP recorded the same photodegradation capabilities. Where they obeyed the Langmuir–Hinshelwood kinetic model (R2 ≥ 0.966) recording the same rate constants (kapp 0.032 min−1) and were efficiently reused for four successive polluted‐water treatment cycles. © 2021 Society of Chemical Industry and John Wiley & Sons, Ltd

“…BDS is more efficient and less expensive than the remaining methods as HDS in removing sulfur from refractory heterocyclic compounds present in crude oil, it could be used in oil refineries as a complement to achieve ULSD. Indeed, BDS can be used to desulfurize heavy oils, as shale oils, which have high thiophene concentration [ 8 ].…”

Biodesulfurization of fossil fuels is a promising method for treating the sour oil due to its environmental friendliness and ability to get rid of the recalcitrant organosulfur compounds. In this study, many types of microorganisms such as Ralstonia eutropha, Rhodococcus erythropolis, Acidithiobacillus ferrooxidans, and Acidithiobacillus thiooxidans applied on a sour heavy crude oil (sulfur content was 4.4%). Also, a colony isolated from the crude oil and oil concentrate was examined by supplying it with PTCC 106. The various official and famous mediums were significantly evaluated such as (PTCC 2, PTCC 105, PTCC 106 (9K), PTCC 116, PTCC 123, PTCC 132), sulfur-free MG-medium, basal salts medium, and mineral salts. It was found that Rhodococcus erythropolis and Acidithiobacillus ferrooxidans from microorganisms and SFM and the medium PTCC 105 were selected as the higher desulfurization efficiencies of crude oil equaling 47 and 19.74% respectively. The bioreactions depend on the treated fluid, targeting sulfur compounds as these represent the environmental status (amounts and types of nutrients), and the type of biotreaters whether microorganism are septic, semiseptic, or aseptic. The optimum operation conditions have been designed by using Definitive method such as mixing speed, temperature, surfactant dose, OWR, acidity. The optimum efficiencies obtained here are better than the previous efforts even though those gained by bioengineering. Biodesalination was a simultaneous process with the BDS.

Abstract: The utilization of desulfurizing microorganisms that can grow in low nutrient culture media without vitamins and other growth promoters (e.g. yeast extract, peptone) is an advantage for BDS upgrade since it may reduce the biocatalyst production costs significantly
