Upper Colorado River (West Texas) and Petronila Creek (Texas Coastal Plain) salinities exceed state regulatory standards. For a recent study, airborne conductivity surveys located points of saline influx. Hydrochemical analyses defined salinity trends and potential sources. Both streams comprise Na-Cl hydrochemical facies and are near hydrocarbon production operations. Upper Colorado River sali...

The legume group is an important source of lipids and fatty acids in animal and human nutrition. As a food source, the neuropharmacological and other potential therapeutic benefits of broad beans (Vicia faba, VF), an ancient plant in cultivation, have been documented. The objective of this study was to evaluate the chemical composition, physiochemical properties and the thermal stability of the...

This paper presents experimental investigation carried out on an unmodified four stroke diesel engine running with preheated straight vegetable oil (SVO) of Karanja. The viscosity of straight karanja oil was reduced by preheating the oil up to 1600C under different load condition. The preheating was done with the help of a Shell and Tube heat exchanger equipment without using any external power...

Deposition of oil residues, also known as tar balls, is a seasonal phenomenon, and it occurs only in the southwest monsoon season along the west coast of India. This has become a serious environmental issue, as Goa is a global tourist destination. The present work aims at identifying the source oil of the tar balls that consistently depositing along the Goa coast using multi-marker fingerprint ...

Chinese quince seed (CQS) is an underutilized oil source and a potential source of unsaturated fatty acids and α-tocopherol-rich oil. Subcritical fluid (SCF) extraction is executed at lower pressures and temperatures than the pressures and temperatures used in supercritical fluid extraction. However, no studies on the SCF extraction of CQS oil are reported. Therefore, the objective of this stud...

AIMS This study aims to establish whether commercially available food oils can be used by Streptomyces clavuligerus as sole carbon sources for growth and clavulanic acid production. METHODS AND RESULTS Batch cultures in bioreactors showed that Strep. clavuligerus growth and clavulanic acid yields in a P-limited medium containing 0.6% (v/v) olive oil were respectively 2.5- and 2.6-fold higher ...

Seed oils provide a renewable source of food, biofuel and industrial raw materials that is important for humans. Although many genes and pathways for acyl-lipid metabolism have been identified, little is known about whether there is a specific mechanism for high-oil content in high-oil plants. Based on the distinct differences in seed oil content between four high-oil dicots (20~50%) and three ...

gundelia tournefortii l. is a well known plant in mountains of iran and is found all over the country. it traditionally has some medicinal applications. in this research, gundelia tournefortii l. seed was studied as a source of edible oil. oil was extracted with immersion method using diethyl ether as a solvent. acidity, saponification, ester, iodine, peroxide and refractive indices, average mo...

The present work was carried out with an aim to isolate an Exo-pectinase producing fungal strain, to optimize physical factors of the enzyme activity and to formulate a media for the cost effective production of the enzyme. Screening, isolation and identification of Aspergillus tamarii and Aspergillus carbonarius were done. Various process variables like pH, temperature and incubation time of t...

Campesterol is an important precursor for many sterol drugs, e.g. progesterone and hydrocortisone. In order to produce campesterol in Yarrowia lipolytica, C-22 desaturase encoding gene ERG5 was disrupted and the heterologous 7-dehydrocholesterol reductase (DHCR7) encoding gene was constitutively expressed. The codon-optimized DHCR7 from Rallus norvegicus, Oryza saliva and Xenapus laevis were ex...
