The present study, details about a halophilic bacterial consortium enriched from water and sediment samples from Red sea, Jeddah, Saudi Arabia analyzed for PAHs degradation potential under saline condition (40 g/L NaCl concentration). The bacterial consortium was able to growth in halophilic mineral salt medium with PAHs (Polycyclic Aromatic Hydrocarbons) as sole carbon source. Different types of selected LMW (Low Mol. Weight) PAHs such as phenathrene (PHN) and fluorine (FLU) at different concentrations (25, 50, 100, 200, 500 ppm) and pyrene (PY) from HMW(High Mol. Weight) PAH at 50 and 100 ppm concentrations was used in the study under saline condition. The results recorded 90% degradation of phenanthrene and fluoreneupto 500 ppm. HMW pyrene revealed 79% and 69% degradation at 50 ppm and 100 ppm concentration under saline condition by the halophilic consortium. Addition of FLU (100 ppm) along with the PY (50 ppm) recorded 85% of PY degradation in 8 days and 98% degradation in 12 days. Addition of yeast extract during PY degradation recorded complete degradation of PY (50 ppm) in 12 days. Lab Scale reactor study with CSTR (continuous stirred tank reactor) used to investigate the PAHs degradation and petroleum refinery wastewater treatment efficiency of in thehalophilic bacterial consortium. The results recorded 95% COD removal in 32 days with complete degradation of LMW PAHs in 12 days under saline condition. Bacterial strains in the consortium were identified by using mol. techniques such as DNA isolation and next generation sequencing.

Wang, Chongyang published the artcileAbsence of the nahG-like gene caused the syntrophic interaction between Marinobacter and other microbes in PAH-degrading process, Recommanded Product: 1-Hydroxy-2-naphthoic acid, the publication is Journal of Hazardous Materials (2020), 121387, database is CAplus and MEDLINE.

In this study, Marinobacter sp. N4 isolated from the halophilic consortium CY-1 was found to degrade phenanthrene as a sole carbon source with the accumulation of 1-Hydroxy-2-naphthoic acid (1H2N). With the assistance of Halomonas sp. G29, phenanthrene could be completely mineralized. The hpah1 and hpah2 gene cluster was amplified from the genome of strain N4, that were responsible for upstream and downstream of PAH degradation Strain N4 was predicted for the transformation from phenanthrene to 1H2N, and strain G29 could transform the produced 1H2N into 1,2-dihydroxynaphthalene (1,2-DHN). The produced 1,2-DHN could be further transformed into salicylic acid (SALA) by strain N4. SALA could be catalyzed into catechol by strain G29 and further utilized by strains N4 and G29 via the catechol 2,3-dioxygenase pathway and catechol 1,2-dioxygenase pathway, resp. NahG, encoding salicylate hydroxylase, was absent from the hpah2 gene cluster and predicted to be the reason for 1H2N accumulation in the PAH-degrading process by pure culture of strain N4. The syntrophic interaction mode among Marinobacter and other microbes was also predicted. According to our knowledge, this is the first report of the PAH-degrading gene cluster in Marinobacter and the syntrophic interaction between Marinobacter and other microbes in the PAH-degrading process.

Luo, Chengyi published the artcileEfficient biodegradation of phenanthrene using Pseudomonas stutzeri LSH-PAH1 with the addition of sophorolipids: Alleviation of biotoxicity and cometabolism studies, Formula: C11H8O3, the publication is Environmental Pollution (Oxford, United Kingdom) (2022), 119011, database is CAplus and MEDLINE.

Phenanthrene (PHE) is widely distributed, and it can cause genotoxicity in humans by interacting with enzymes in the body. A current challenge for PHE bioremediation is the inhibitory effect of biotoxic intermediates on bacterial growth. Notably, the aerobic biotransformation processes for PHE in the presence of sophorolipids have been poorly studied. Here, a PHE-degrading strain was isolated from sediments and identified as Pseudomonas stutzeri and named LSH-PAH1. It was observed that 1-naphthol (a biotoxic substance that can inhibit strain growth) was produced during the PHE metabolism process of LSH-PAH1. The biodegradation ratio increased from 21.4% to 91.7% within 48 h after the addition of sophorolipids. Unexpectedly, this addition accelerated the metabolic process for 1-naphthol rather than causing its accumulation. The cometabolism of 1-naphthol and sophorolipids alleviated the biotoxic effects for the strain, which was verified by gene expression anal. We identified a new PHE-degrading strain and provided a mechanism for PHE biodegradation using LSH-PAH1 with the addition of sophorolipids, which provides a reference for practical applications of the bioremediation of PHE and study of the cometabolism of biotoxic intermediates.

Liu, Caiyun published the artcileBinding Modes of Salicylic Acids to Titanium Oxide Molecular Surfaces, HPLC of Formula: 86-48-6, the publication is Chemistry – A European Journal (2020), 26(12), 2666-2674, database is CAplus and MEDLINE.

A set of titanium oxide clusters (TOCs) comprised of 4 to 16 Ti atoms are synthesized with substituted salicylates (SSAs). The interfacial coordination environment of these SSA/Ti oxide hybrids are surveyed and found to be limited to four binding modes, with the bridging chelate mode being the most common one. The SSA-functionalized TOCs show strong visible light absorption properties. The contribution of the SSAs in the frontier orbitals of the TOCs are analyzed by using TD-DFT calculations based on the mol. geometries determined by X-ray diffraction. For TOCs of relatively high O/Ti ratio, the SSAs narrow the band gap of the TOCs by contributing solely to the HOMOs. Both binding modes and locations of the SSAs are important for the roles of SSAs in changing the HOMOs and thereby the absorption onsets.

Al Farraj, Dunia A. published the artcileCharacterization of pyrene and chrysene degradation by halophilic Hortaea sp. B15, SDS of cas: 86-48-6, the publication is Bioprocess and Biosystems Engineering (2019), 42(6), 963-969, database is CAplus and MEDLINE.

Polycyclic aromatics hydrocarbons (PAHs) are ubiquitous and toxic pollutants that are dangerous to humans and living organism in aquatic environment. Normally, PAHs has lower mol. weight such as phenanthrene and naphthalene that are easy and efficient to degrade, but high-mol.-weight PAHs such as chrysene and pyrene are difficult to be biodegraded by common microorganism. This study investigated the isolation and characterization of a potential halophilic bacterium capable of utilizing two high-mol.-weight PAHs. At the end of the experiment (25-30 days of incubation), bacterial counts have reached a maximum level (over 40 × 10¹⁶ CFU/mL). The highest biodegradation rate of 77% of chrysene in 20 days and 92% of pyrene in 25 days was obtained at pH 7, temperature 25°C, agitation of 150 rpm and Tween 80 surfactant showing to be the most impressive parameters for HMWPAHs biodegradation in this research. The metabolism of initial compounds revealed that Hortaea sp. B15 utilized pyrene to form phthalic acid while chrysene was metabolized to form 1-hydroxy-2-naphthoic acid. The result showed that Hortaea sp. B15 can be promoted for the study of in situ biodegradation of high mol. weight PAH.

Semleit, Nina published the artcileControlling the Gold(I)-Catalyzed 1,5-Allenene Reaction: Construction of Fused Rings with Excellent Diastereoselectivity, Category: alcohols-buliding-blocks, the publication is Organic Letters (2021), 23(24), 9635-9639, database is CAplus and MEDLINE.

In the present study, the gold(I)-catalyzed reaction of 1,5-allenenes was controlled in such a way that instead of a [2+3] cycloaddition, a 5-exo-cyclization with the formation of a carbocation occurred. The latter could be trapped with both oxygen and carbon nucleophiles. In the investigated system, fused tricyclic frameworks I (R = Me; R¹ = Me, Cl, Br, etc.; Nu = OMe, OEt, 2-furyl, etc.) with three contiguous stereocenters with excellent chemo- and diastereoselectivity in up to 95% yield were obtained.

Barua, Harsh published the artcileAn ab initio molecular dynamics method for cocrystal prediction: validation of the approach, COA of Formula: C11H8O3, the publication is CrystEngComm (2019), 21(47), 7233-7248, database is CAplus.

Cocrystals offer exciting opportunities to the scientists, with options of tuning their physicochem., biopharmaceutical, and mech. properties simultaneously, which can expand the solid form diversity of drugs. Herein, for overcoming the need for exhaustive exptl. work and improving the chances of success in the selection of coformers, a computational prediction approach has been developed. In this study, a new cocrystal prediction methodol. employing hydrogen bonding tendency, evaluated with the aid of mol. dynamics, has been utilized. For validation, the exptl. results of 145 coformers with 6 drugs have been used. The method was found to significantly reproduce the exptl. results with attractive features of being a simple, easy-to-use protocol, with short computational time. Further, the developed model was used to predict the formation of cocrystals of nitrofurantoin against a library of new coformers. Three out of the four new cocrystals formed were correctly predicted by the developed prediction methodol. The cocrystal formation of 89 coformers out of a total of 145 coformers was correctly predicted. Thus, the reasonable degree of success obtained in predicting and exptl. generating new cocrystals of nitrofurantoin indicates that the developed computational methodol. can play an important role in screening a large library of coformers in the future.

Wang, Yekai published the artcileMetabolic signature of the aging eye in mice, HPLC of Formula: 86-48-6, the publication is Neurobiology of Aging (2018), 223-233, database is CAplus and MEDLINE.

Aging is a major risk factor for age-related ocular diseases including age-related macular degeneration in the retina and retinal pigment epithelium (RPE), cataracts in the lens, glaucoma in the optic nerve, and dry eye syndrome in the cornea. We used targeted metabolomics to analyze metabolites from young (6 wk) and old (73 wk) eyes in C57 BL6/J mice. Old mice had diminished electroretinogram responses and decreased number of photoreceptors in their retinas. Among the 297 detected metabolites, 45-114 metabolites are significantly altered in aged eye tissues, mostly in the neuronal tissues (retina and optic nerve) and less in cornea, RPE/choroid, and lens. We noted that changes of metabolites in mitochondrial metabolism and glucose metabolism are common features in the aged retina, RPE/choroid, and optic nerve. The aging retina, cornea, and optic nerve also share similar changes in NAD (NAD), 1-methylnicotinamides, 3-methylhistidine, and other methylated metabolites. Metabolites in taurine metabolism are strikingly influenced by aging in the cornea and lens. In conclusion, the aging eye has both common and tissue-specific metabolic signatures. These changes may be attributed to dysregulated mitochondrial metabolism, reprogrammed glucose metabolism and impaired methylation in the aging eye. Our findings provide biochem. insights into the mechanisms of age-related ocular changes.
