In this study, the hybitd reactor has used to remove H_2S from the toxic gas. Since the oxidation and reduction reactors were combined, theri sizes were important to stabilize developed process. The optimal sizes of oxidation and reduction reactors were determined considering iron oxidation rate and H_2S removal rate. The optimal ratio of reactor size was 4 L for oxidation reactor to 1 L for reduction reactor.Immobilized Thiobacillus ferrooxidans has been developed to minimize the size of oxidation reactor. Since the immobilized cell enhanced the oxidation rate, it was possible to incrase H_2S removal efficiency. It was possible to incerase operation time because immobilized cell can survie lger than free cell.

유주현,홍대희,양융,진효상 연세대학교 산업기술연구소 1986 논문집 Vol.18 No.1
The cellulase of verticillium sp. was purified to investigate its some properties. The enzyme purification was carried out by ammonium sulfate fractionation, and column chromatography of Sephadex G-50, G-100 and DEAE Sephadex A-25, with its specific activity increased to 17 fold. The molecular weight was estimated to be 46,000 by gel filtration. The optimum pH and temperature were pH 7 and 50℃, respectively. The enzyme was stable over the range of pH5-7 at 50℃ for 1 hour. But half of its activity was lost after 2 hour. The km value was calculated to be 1.2mg of CMC/㎖.

Purpose: The ratio of soluble fms-like tyrosine kinase 1 (sFlt-1) to placental growth factor (PlGF) is considered a predictive marker of preeclampsia. However, the relationship between the sFlt-1/PlGF ratio and perinatal and neonatal outcomes remains unknown. This study aimed to determine the associations of the sFlt-1/PlGF ratio with perinatal and neonatal outcomes in newborns born to mothers with preeclampsia. Methods: This retrospective cohort study reviewed singleton neonates born to mothers with preeclampsia who underwent testing for the sFlt-1/PlGF ratio. We investigated the relationship between maternal sFlt-1/PlGF ratios and gestational age (GA), birth weight (Bwt), Bwt z-score, morbidities, and mortality of neonates born to mothers tested for the sFlt-1/PlGF ratio. Maternal sFlt-1/PlGF ratios examined within 30 days before delivery were used for analysis. Neonatal morbidities and mortality were investigated only in preterm infants born earlier than 32 weeks GA. Results: A total of 225 neonates were included, of which 163 (72.4%) were preterm infants. GA (R=– 0.577, P<0.001), Bwt (R=–0.713, P<0.001), and Bwt z-score (R=–0.608, P<0.001) exhibited significant negative correlations with the sFlt-1/PlGF ratios. Among the 50 preterm infants born earlier than 32 weeks GA, neonatal morbidities were not significantly associated with the sFlt-1/PlGF ratio after adjusting for GA and Bwt. Conclusion: In mothers with preeclampsia, a higher sFlt-1/PlGF ratio was associated with the delivery of newborns with lower GA and lower Bwt. However, this ratio was not associated with increased morbidity or mortality in premature infants born earlier than 32 weeks GA.

This study investigated the probiotic and functional characteristics of Mukeunji starter, Lactobacillus curvatus ML17, isolated from Mukeunji. Lb. curvatus ML17 was confirmed as a safe microorganism due to its non-hemolytic activity and non-production of harmful β-glucuronidase and β-glucosidase. Tolerance to artificial gastric and bile juice of Lb. curvatus ML17 was investigated. After incubation in artificial gastric and bile juice, the number of surviving cells was 1.38×10<SUP>8</SUP> CFU/mL. According to the results of adhesion assay, this strain also exhibited good adhesion to Caco-2 cells. Lb. curvatus ML17 showed good antimicrobial activity against food borne pathogens, especially Micrococcus luteus, Bacillus cereus, Salmonella enterica subsp. enterica, and Pseudomonas aeruginosa. Cell-free extract of Lb. curvatus ML17 exhibited high levels of DPPH scavenging capacity and inhibitory effects on growth of AGS human gastric adenocarcinoma cells and HT-29 human colon carcinoma cells. These results suggest that Lb.curvatus ML17 has potential for application in functional foods.
