“…That might be attributed to the occurrence of the feedback inhibition phenomenon caused by the accumulation of 2‐HBP. 2‐HBP is known to inhibit microbial growth and the enzymatic system 61 . The batch DBT‐BDS process using R. jialingiae HN3 was found to follow the second‐order kinetic model equation (R 2 ≥ 0.9388), where the rate constant increased sixfold after applying optimum concentrations of CSL and bioglycerol, recording 0.0001 and 0.0006 L mg −1 h −1 with t 1/2 values of 116 and 9.17 h, respectively.…”

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

“…Biodesulfurization (BDS) proposed as a cost effective and environmentally safe process for removal of recalcitrant sulphur compounds from petroleum fractions, under mild operational pressure and temperature [9]. However, the limited versatility of microorganisms towards the different sulphur compounds in real oil feed [10,11], and their tolerance to solvents and hydrocarbons limit its applicability on industrial scale. Further, the bioavailability of organosulfur compounds in oil phase to microbial culture in aqueous phase is another obstacle that should be solved [9].…”

The presence of sulphur in petro-diesel has negative impact on engine performance and environment. In this work, a novel hydrocarbon tolerable Paenibacillus glucanolyticus HN4 denoted NCBI Gene Bank Accession No. MT645230; has been isolated from oil polluted sediment sample collected from Egyptian Red sea shoreline. Two-phase system enrichment medium containing 100 mg/l dibenzothiophene (DBT) dissolved in n-hexadecane (1/4 oil/water v/v) was used for selective enrichment and isolation of biodesulfurizing bacterium. HN4 desulfurized DBT as a model sulphur compound without affecting its hydrocarbon skeleton via the 4S-pathway producing 2-hydroxybiphenyl (2-HBP) as a dead end product. HN4 proved to be a hydrocarbon tolerant, biosurfactants(s) producer and endorsed a unique enzymatic system capable of desulfurizing both BTs and DBTs. Where, it desulfurized broad range of thiophenic compounds and expressed an efficient desulfurization activity against the recalcitrant alkylated DBTs. One-Factor-At-A-Time (OFAT) optimization technique illustrated approximately 90% biodesulfurization efficiency (%BDS) in an oil-water two-phase batch process at optimal operational conditions of; 120 h, 0.05 wt.% S-content model oil (DBT dissolved in n-hexadecane), 30 o C, pH7 and 1/1 oil/water phase ratio. HN4 decreased the sulphur content of a petro-diesel from 0.2 wt.% to 0.04 wt.%, in an 1/1 (v/v) oil-water two-phase batch BDS process, without affecting its calorific value. Consequently, that novel strain is recommended to be promising candidate for BDS as a complementary process for hydrodesulfurization technique in oil refinery.

“…The concentration of dibenzothiophene is a parameter measured for desulfurization because it is the most significant organic sulfur in coal (Constanti et al, 1994;Jatoi et al, 2021) and has become an internal standard for assessing coal maturation (Li et al, 2012). In addition, the desulfurization of dibenzothiophene also means the attack of other organic compounds because the microorganisms that desulfurize the compound can use a wide range of sulfur compounds as substrates (Chen et al, 2019;Nassar et al, 2021).…”

Efforts to reduce organic sulfur in coal are taken through biodesulfurization by using desulfurization bacteria to release covalently-bound sulfur from the coal matrix. Coal is a complex hydrocarbon material that requires collaboration from more than one type of bacteria in a consortium for desulfurization. The current study shows how the individual members of a bacterial consortium obtained directly from coal samples grew on the coal. Mineral medium containing sub-bituminous coal with a concentration of 10%, 15%, and 20% served as a carbon source and the only sulfur to support the consortium's growth. The examination included growth patterns, concentrations of dibenzothiophene as an organic sulfur representative, pH, and sulfate concentration as the sulfur product released into the medium. The growth of individual members of the consortium was observed for 336 h. The consortium grew in all three coal concentrations with slightly different cell growth patterns and the release of dibenzothiophene. Members of the consortium grew alternately and overlapped, which showed possible linkages or dependence on products and existence from the growth of other members. The existence of the primary strain Moraxella osloensis COK1 indicated that they played a role in the activities and growth of other members. The alternating growth is discussed to produce a hypothetical illustration of how several other members play in using sulfur in a well-known desulfurization pathway. In conclusion, this study provides a deeper insight into the value of consortium members individually but growing together while swarming coal as a complex resource to become low-sulfur coal.
