The strain MA428-C1 was shaken-cultured (120 strokes/min., 8 cm amplitude) in. a medium (pH7.0) containing 2% glucose, 1.5% soybean meal, 0.3% NaCl, 0.1% K2HPO4, 0.1 % MgSO4-7H2O, 0.0007 % CuSO4-5H2O, 0.0001 % FeSO4-7H2O, 0.0008 % MnCl2-4H2O, 0.0002% ZnSO4-7H2O at 27°C for 5 days. The amount of gougeroxymycin was determined by a cylinder plate method described by one of the authors1}.. About 70...

Morus alba leaf methanolic extract and its fractions (chloroform, butanol, and aqueous fractions) were found to inhibit NO production in LPS-activated RAW264.7 macrophages without an appreciable cytotoxic effect at concentration from 4 to 100 microg/ml. LPS-induced PGE2 production was significantly reduced only by butanol fraction. In addition, M. alba leaf extract and its fractions significant...

In this study, the in vivo effect of the crude extract and n-butanol and aqueous residual fractions of Baccharis articulata (Lam.) Pers. on serum glucose levels, insulin secretion and liver and muscle glycogen content, as well as in vitro action on serum intestinal disaccharidase activity and albumin glycation were investigated. Oral administration of the extract and fractions reduced glycemia ...

In this study, microemulsions of the chiral surfactant polysodium N-undecenoyl-D-valinate (poly-D-SUV) was utilized for enantiomeric separation by investigating two approaches using polymeric chiral surfactant in microemulsion electrokinetic chromatography (MEEKC). In the first approach, poly-D-SUV was used as an emulsifier surfactant along with 1-butanol and n-heptane. Enantioseparation of ani...

[15(O)]Butanol has been shown to be superior to [15(O)]water for measuring cerebral blood flow with positron emission tomography. This work demonstrates that it is also superior for performing activation studies. Data were collected under three conditions: a visual confrontation animal-naming task, nonsense figure size discrimination, and a nonvisual darkroom control task. Time-activity curves ...

The negative impact of transport on climate has led to incentives increase the amount renewable fuels used in internal combustion engines (ICEs). Oxygenated, liquid biofuels are promising alternatives, as they exhibit similar behaviour gasoline. In this article, effect different engine efficiency, propagation and emissions a gasoline-optimised direct injected spark ignited (DISI) were evaluated...

In this work, poly (ether-block-amide) (PEBA)/ceramic hollow fiber (HF) composite membranes with high flux were prepared by dip-coating the ceramic hollow fiber with PEBA polymer solution for pervaporation (PV). The membrane fabrication was optimized by finely tailoring the coating parameters such as the viscosity and concentration of PEBA coating solution, which made the pervaporation flux as ...

Microbial production of higher alcohols from renewable feedstock has attracted intensive attention thanks to its potential as a source for next-generation gasoline substitutes. Here we report the discovery, characterization and engineering of an endogenous 1-butanol pathway in Saccharomyces cerevisiae. Upon introduction of a single gene deletion adh1Δ, S. cerevisiae was able to accumulate more ...

The purpose of this study was to examine the effect of noncytolytic 1-butanol extraction of cell membrane compo nents upon the metastatic potential of i.v. injected neoplastic cells. Butanol extraction consistently increased the number of pulmonary, but not extrapulmonary, lesions observed following challenge of (a) C3H/HeJ mice with the chemically induced fibrosarcoma MCA-F or (b) C57BL/6J mic...
