Mitigation of sulfate reducing Desulfovibrio ferrophilus microbiologically influenced corrosion of X80 using THPS biocide enhanced by Peptide A

作者： Junlei Wang Hongfang Liu Magdy El-Said Mohamed Mazen A.saleh Tingyue Gu Department of Chemical and Biomolecular Engineering Institute for Corrosion and Multiphase TechnologyOhio UniversityAthensOH 45701USA School of Chemistry and Chemical Engineering Huazhong University of Science and TechnologyWuhan 430074China Research and Development Center Saudi Arabian Oil CompanyDhahran 31311Saudi Arabia

Tetrakis hydroxymethyl phosphonium sulfate(THPS) was enhanced by a 14-mer Peptide A, with its core12-mer sequence mimicking part of Equinatoxin II protein, in the mitigation of sulfate reducing Desulfovibrio ferrophilus MIC(microbiologically influenced corrosion) of X80 carbon steel. Results proved that50 ppm(w/w) THPS was sufficient to mitigate the D. ferrophilus biofilm, and its very agressive MIC(19.7mg/cm^(2) in 7 days or 1.31 mm/a), but not 20 ppm THPS. To achieve effective mitigation at a low dosage of THPS, biofilm-dispersing Peptide A was added to 20 ppm THPS in the culture medium. Sessile cell counts were reduced by 2-log and 4-log after enhancement by 10 ppb and 100 ppb Peptide A, respectively. Enhancement efficiency(further reduction in corrosion rate) reached 69% for 10 ppb Peptide A and 83% for100 ppb Peptide A compared with 20 ppm THPS alone treatment, indicating that Peptide A was a good biocide enhancer for THPS.

Antihyperglycemic and hepatoprotective properties of miracle fruit(Synsepalum dulcificum) compared to aspartame in alloxan-induced diabetic mice

Journal of Integrative Medicine 2020年第6期18卷 514-521页

Objective: This study was undertaken to investigate the antihyperglycemic potential of miracle fruit(MF)as well as its hepatic safety as compared to aspartame in alloxan-induced diabetic ***: MF extracts were prepared and screened for their phytochemical composition using highperformance liquid chromatography(HPLC). Total phenolic, flavonoid and tannin contents and antioxidant potential were also determined. Additionally, MF was evaluated for its sensory attributes. For in vivo work, MF ethanol extract at high(MFH: 500 mg/kg body weight [BW]) and low(MFL: 250 mg/kg BW) doses as well as aspartame were injected intraperitoneally into alloxan-induced diabetic *** glucose levels were determined following acute and subchronic treatment. At the end of the study,animals were sacrificed, serum was collected for biochemical analysis and liver tissues were obtained for histopathological ***: MF ethanol extract contained more flavonoids and tannins, and had higher 1,1-diphenyl-1-picrylhydrazyl radical-scavenging activity(79.61%) compared to MF aqueous extract(P < 0.05). HPLC analysis of MF ethanol extract also revealed the presence of 10 antioxidants with quercetin comprising the major polyphenol. Additionally, sensory analysis of MF showed that its intake is effective in masking undesirable sourness. Subchronic administration of MFH proved amelioration of hyperglycemia in mice as compared to aspartame. Moreover, aspartame treatment significantly elevated(P < 0.05) the level of alanine aminotransferase and had destructive effects on the liver histopathology;however, hepatic architecture was restored by low and high doses of ***: MF is an effective antihyperglycemic with hepatoprotective properties that can be used as a healthier alternative sweetening agent in place of aspartame for sour beverages.
