The submerged fermentation for extracellular polysaccharide (EPS) production from Trametes gibbosa was optimized. An optimal medium for EPS production was obtained through central composite design (CCD) as follows: 53.12 g/L maltose and 4.21 g/L polypeptone in distilled water. Furthermore, four groups of EPSs (designated as Fr-I, Fr-II, Fr-III and Fr-IV) were obtained from the culture filtrates by size exclusion chromatography (SEC), and their molecular characteristics were examined by a multiangle laser-light scattering (MALLS) and refractive index (RI) detector system. The weight-average molar mass of Fr-I was determined to be 3.872 × 105 g/mol and its molecular shape was revealed to be a rigid rod in an aqueous solution. Finally, the hypoglycemic effect of the EPS, investigated in streptozotocin induced diabetic mice, decreased plasma glucose, total cholesterol and triacylglycerol concentrations by 17.4%, 14.0% and 12.6%, respectively. The results indicate the potential of this EPS to prevent hyperglycemia in diabetic patients. © 2013 Elsevier Ltd. All rights reserved.

In recent years, the rapid development of computer technology and modern communication technology promote the industrial control system model to occure a essentially change. Modern industrial control mode is gradually developing towards information technology, networking, universal and intelligent. While compared with rapid integration of information technology and industrialization, the information security development is lagging behind, resulting in the growing industry information security. In order to enhance the understanding of the industry's status quo for industrial control and information security requirements and standards, in this paper, the cigarette industry is taken as the background, and detailed the potential risks of industrial control and information security solutions. © 2014, Trans Tech Publications, Switzerland.

In order to blend the cut tobacco in a processing batch more precisely and ensure blend consistency, all factors influencing blending processing were analysed on an instantaneous precision basis, and the screen for dried cut strips and proportioning weigher were improved. A loosening device was installed above the vibration screen to loosen tangled tobacco and optimize its size composition, and a spreader was installed at the discharge end of the proportioning weigher to avoid tobacco jam and ensure the continuity of tobacco flow. The results showed that: 1) Tobacco loosening, the uniformity and stability of instantaneous flow were the key factors influencing the consistency of tobacco makeup in a cigarette; 2) After improvement, the instantaneous blending precision reduced from 1.84% to 1.09% and the deviation of actual makeup in cigarettes decreased from 1.30% to 0.79%. Tobacco was well loosened and tobacco jam avoided, the quality control and process control in cigarette manufacturing were effectively improved. ©, 2014, Editorial Office of Tobacco Science and Technology.

Aiming at the large fluctuation and frequent interruption of tobacco flow in primary processing line, the spiker plate in elevator, metering tube and control program were improved with speed regulation linkage technology. The length of spikers on the spiker plates was shortened from 15 to 10 cm and the vertical distance between the spikers and picker roller was adjusted to 8 mm to avoid interrupted tobacco conveying caused by long spikers and maintain a steady flow. An auxiliary detection chamber was added inside the metering tube to counteract air current in metering tube and prevent misoperation of photoelectric cell. Speed regulation linkage technology was adopted to match the speed of the elevator with that of the belt weigher and adjust tobacco flow. The results of application showed that, the average fluctuation of tobacco flow reduced from 0.9% to 0.5% , the frequency of tobacco interruption decreased from 15 times per shift to lower than 10 times per month.

Reduced fluctuation of key parameters during tobacco strips loosening and conditioning may help to improve process control system. Improved control of recirculated air and moisture content can result in optimized process parameters which further help to reduce fluctuation of output moisture content and temperature. The average standard deviation of output moisture content was reduced to 0.24% from 0.43%. By so doing both operation stability and process control reliability were enhanced. ©, 2015, State Tobacco Monopoly Bureau and China Tobacco Society. All right reserved.
