The study was conducted to evaluate the physicochemical properties and fatty acids content of lard. qualitative determination using GC-MS analysis revealed that higher concentrations 9- octadecenoic acid methyl ester Hexadecenoic acid, stearate 9,12-Octadecadienoic (Z,Z)- with different concentrations. Many physical chemical lard were determined in including density, viscosity, refractive index...

The stable of natural diatomite supported by potassium hydroxide (KOH) as catalysts were synthesized for biodiesel production. A heterogeneous base catalyst prepared impregnating KOH onto was also used to synthesize from palm oil. All samples have been thoroughly characterized Wavelength Dispersive X-ray Fluorescence (WDXRF), diffraction (XRD), N2 adsorption/desorption, Scanning electron micros...

Two complementary studies were performed to examine (1) the effect of 18 years of nitrogen (N) fertilization, and (2) the effects of N fertilization during one growing season on soil microbial community composition and soil resource availability in a grassland ecosystem. N was added at three different rates: 0, 5.44, and 27.2 gNm 2 y . In both studies, Schizachyrium scoparium was the dominant p...

Promising energy crops such as Jatropha curcas Linnaeus (JCL), which are planted on marginal lands, or microalgae such as Chlorella, which are cultivated in ponds located on mudflats or deserts, have been regarded with high hopes to solve the shortage of food crops and increase the amount of biodiesel (Fatty Acid Methyl Ester, FAME) production. However, the annual yields of biomass and transpor...

A polyphasic study of strains originally received as Bacillus (now Virgibacillus) pantothenticus, along with strains representing species belonging to Bacillus, Halobacillus and Paenibacillus, was undertaken using amplified rDNA restriction analysis (ARDRA), fatty acid methyl ester (FAME) analysis, SDS-PAGE of whole-cell proteins and routine diagnostic characters comprising 61 biochemical tests...

Although the pimeloyl moiety was long known to be a biotin precursor, the mechanism of assembly of this C7 α,ω-dicarboxylic acid was only recently elucidated. In Escherichia coli, pimelate is made by bypassing the strict specificity of the fatty acid synthetic pathway. BioC methylates the free carboxyl of a malonyl thioester, which replaces the usual acetyl thioester primer. This atypical prime...

Smoking of meats and fish is one of the earliest preservation technologies developed by humans. In this study, the smoking process was evaluated as a method for reducing oxidation of pink salmon (Oncorhynchus gorbuscha) oils and also maintaining the quality of oil in aged fish prior to oil extraction. Salmon heads that were subjected to high temperatures (95 degrees C) during smoking unexpected...

This work aimed a survey on the biodiversity of maize endophytic actinomycete, and an evaluation of their potential to control the phytopathogenic fungi. From several regions of São Paulo state, 40 strains were isolated from the healthy maize plants. The identification of these strains, based on morphological properties and fatty acid methyl ester (FAME) profile showed that most of them belonge...

The reaction was studied by incubation of fatty acid with S-adenosyhnethionine-methylJ4C and isolation of the labeled ester. This was characterized by thin layer and gas-liquid chromatography and by isolation of labeled methanol from alkaline hydrolysates of the ester. Of several substrates tested only S-adenosylmethionine was an effective methyl donor (K,,, = 2.5 X 10F5 M) and oleic acid was t...
