The crystallization index (CrI) of BC/CNTs acetate was better than BC acetate, i.e. 97 : 3 and 93 : 7, respectively. The crystallite size of BC microfibrils in BC/CNTs sheet was reduced because of the impregnated CNTs. However, the reduction of crystallite size for BC/CNTs acetate was lower than that of BC acetate showing that the existence of CNTs within BC micofibrils had protected the BC crystal structure from further destruction by acetylating agent.
CONCLUSION: CNTs is a powerful substance that acted as a void filler between BC crystalline structure and protected
the nano-biocomposite from total degradation selleck by the acetylation process. (C) 2011 Society of Chemical Industry”
“Lactoferrin (LF) is one of the prebiotics present in the human body. A 38-year-old multiparous woman with poor obstetrical histories, three consecutive preterm premature rupture of membrane at
the 19th, 23rd and 25th week of pregnancy, was referred to our hospital. She was diagnosed as having refractory vaginitis. Although estriol vaginal tablets were used for 4 months, the vaginitis was not cured. We administrated vaginal tablets and oral agents of prebiotic LF, resulting in a Lactobacillus predominant vaginal flora. When she was pregnant, Rabusertib she continued to use the LF, and the Lactobacillus in the vaginal flora was continuously observed during pregnancy. An elective cesarean section was performed at the 38th week of pregnancy. When the administration of LF was discontinued after the delivery, Lactobacillus in the vaginal flora was disappeared.”
“BACKGROUND: Effluent released from industry is a mixture of various pollutants. For the degradation of
complex pollutants, mixed bacterial cultures can be more effective than a single culture. This study investigated the balance of bacterial populations in a mixed culture for maximum reduction of pollutants.
RESULTS: This study deals with the degradation and detoxification of pulp papermill effluent (PPME) by three bacterial strains, i.e. Serratia marcescens, Serratia liquefaciens and Bacillus cereus in different ratios, and found that two ratios, NVP-HSP990 nmr 4 : 1 : 1 and 1 : 4 : 1, were effective for the degradation of PPME. These ratios reduced the various pollution parameters. Enzyme bioassay revealed that more enzyme was produced during degradation for the ratio 4 : 1 : 1. High performance liquid chromatography (HPLC) analysis showed that the ratio 4 : 1 : 1 degraded 95% of lignin and related compounds, and chlorophenols up to 98%, whereas ratio 1 : 4 : 1 reduced lignin by 84% and chlorophenols by 58% after 7 days incubation. Degradation products were confirmed by gas chromatography-mass spectrometry (GC-MS) analysis. A seed germination bioassay on Phaseolous mungo L. revealed that toxicity was reduced by the ratio 4 : 1 : 1.
