Comparative characterization of extracellular and intracellular hydrocarbons of Clostridium pasteurianum

Extracellular and intracellular hydrocarbons produced by Clostridium pasteurianum VKM 1774 during cultivation on glucose-containing media in an argon atmosphere or in the presence of carbon dioxide and molecular hydrogen were analyzed by gas-liquid chromatography. Intracellular hydrocarbons were 50-55% (C25-C35) n-alkanes. Carbon dioxide and molecular hydrogen stimulated synthesis of extracellular hydrocarbons, which comprised 90-95% (C11-C24) n-alkanes

Innovation as a part of strategic management and enterprise competitiveness of petrochemical cluster

© 2016 Taylor & Francis Group, London.In this paper, we have investigated an innovative development of petrochemical cluster in the Republic of Tatarstan, the main trends and factors to improve its competitiveness through innovation were identified. It contains clarification of the notion of strategic management of innovative development of the petrochemical cluster, and the basic management practices that improve the investment and innovation activity of petrochemical industries were considered

Factors of functioning and development of tourist clusters at regional level

Under the condition of tough competition, lack of proper support for tourist industry at the state level, and necessity for development and bringing this sector to a new level, which consists in capability for offering a consumer a high-quality and competitive product, the necessity for search for effective solutions is obvious. One of the perspective and effective means for solving the problems of tourist sphere at present is formation and development of tourist clusters. The article studies existing approaches to determination of tourist cluster, analyzes the current state of internal tourism, and views factors which hinder the creation of competitive product and factors which stipulate the increase of effectiveness of functioning of tourist clusters at regional level

Research of vegetable oils oxidation process in the deep fat during thermal treatment

Change of deep fat quality indexes significantly influencesthe formation of consumer properties of fried products, and correctly matched fat raw materials guarantee its quality and safety. In this paper the analysis of vegetable oils use prospects (sunflower, palm, rapeseed, corn, linseed, mustard) as deep fat was carried out. For an assessment of the oxidizing processes, which occur in the deep fat at heat treatment, peroxide, iodine and acid index values were chosen. The analysis of organoleptic, physical and chemical indexes of the studied vegetable oils and the deep fried production showed usefulness of mustard and linseed oils as deep fat for not more than 1 h usage, sunflower and corn - not more than 2 h, and palm and rapeseed - not more than 3 h. Besides, it was revealed that use of rapeseed oil slows down the process of deep fat thermal oxidation. Thus, decrease in rates of primary products of oxidation formation was observed, as well as reduction in the number of secondary oxidation products. At the same time it was noted that the use of rapeseed oil makes it possible to reduce the specific consumption of deep fat, as well as to extend its continuous use while maintaining the organoleptic characteristics of the fried products

THE CHOICE OF IONIT FORM FOR SORPTION OF LANTANUM AND CERIUM FROM SULFURIC ACID SOLUTIONS

The choice of ionic form of cation exchanger Dowex Marathon C for effective sorption of La and Ce from sulfuric acid solutions was carried out. The ammonium form of cation exchanger was chosen because of high values of sorption of both elements

KINETIC OF SORPTION OF SCANDIUM AND IMPURITIES FROM HYDROLISIS SULFURIC ACID BY AMPHOLYTE PUROLIE S950

The kinetic of sorption of Sc, Zr, Al, Th, Ti and Fe from the hydrolysis sulfuric acid by using ampholyte Purolite S950 was investigated. The limiting stage of sorption of Sc and Zr was internal diffusion, and the sorption of Ti, Al, Fe and Th was carried out in a mixed-diffusion mode

LANTHANUM AND CERIUM SORPTION WITH DOWEX MARATHON C CATIONITE

The sorption of lanthanum and cerium from sulfuric acid solutions with Dowex Marathon C cationit in the static mode was studied. The isotherms of lanthanum and cerium sorption are described by the Langmuir model
