Retention of NAD(H) in non-charged ultra-fitration membrane reactor

Huagong jinzhan (2008)

Zongding Hu

Retention of NAD(H) was investigated in a self-built non-charged ultra-filtration membrane reactor.NAD(H) was retained effectively by ultra-filtration membrane in the presence of 50kDa polyethyleneimine(PEI).High retention ratio(R=0.823) was obtained with PEI/ NAD+ molar ratio 5:1 in Tris-HCl buffer.The increase of solution ionic strength caused a decrease of coenzyme retention but an increase of the permeation flux.The addition of 0.5% or 1% bovine serum albumin enhanced the coenzyme retention,minimizing the effect of ionic strength.The retention ratio of NADH was higher than that of NAD+ in PEI system.The influence of PEI on the activities of glycerol dehydrogenase and 1,3-propanediol oxidoreductase was also studied.

STUDIES ON NUTRITION PHYSIOLOGY AND COMPARTMENTALIZATION OF CELL AGGREGATES IN CELL SUSPENSION CULTURE OF TAXUS CHINENSIS VAR.MAIREI

Journal of Tianjin University Science and Technology (2001)

Zongding Hu

By observing the section of cell aggregates under an optical microscope and measuring the content of starch grains,soluble protein,biomass and taxol,it was found that there were different compartments in cell aggregates.The starch grains were distributed mainly in the surfacce layer.In the case of starch metabolism,it was preliminarily demonstrated that these compartments have different functions,and it was proposed that the nutrient gradient was an important reason of differentiation of morphology and function of cell compartments in cell aggregates in cell suspension culture.

Fractal Structure in Gas–Liquid–Solid Circulating Fluidized Beds with Low Solid Holdups of Macroporous Resin Particles

Industrial & Engineering Chemistry Research (2013)

Jianhua Liu Mingyan Liu Zongding Hu

The fractal structures of flow images of gas–liquid–solid circulating fluidized beds (GLSCFBs) with low solid holdups of macroporous resin particles at different operating conditions and liquid physical properties were investigated by the fractal analysis method. The images were obtained with the high-speed image acquisition and treatment system of complementary metal oxide semiconductor (CMOS). The results show that the structure of the gas–liquid–solid circulating flow exhibits certain fractal behavior and the fractal dimension D can be used to describe the multiphase self-organization flow structure from the point of view of geometry. The fractal dimension changes with the phase holdup and the agglomeration degree of bubbles or/and particles. Generally, higher solid or gas holdup leads to larger fractal dimension and more extensive aggregation or self-organization degree results in lower entropy and thus lower fractal dimension. In order to avoid the appearance of the aggregation in the GLSCFB riser, higher superficial velocity of primary liquid flow, lower superficial velocity of auxiliary liquid flow, and lower liquid surface tension may be exerted.

Synergistic Effects of Fructose Feeding and Fungal Elicitor on Taxus chinesis var.mairei Suspension Cultures

Chemical Engineering(China) (2003)

Zongding Hu

By feeding fructose and fungal elicitor at the same time to suspension cultures of Taxus chinesis var. mairei in the late exponential stage, cell growth status and taxane production were studied. The results show that synergistic effects of fructose feeding and fungal elicitor changed the cell physiological status, induced alkalinization of medium and decreased the cell biomass. The content of protein representing quantity of enzymes increased. Phenolics were largely accumulated. The taxol yields in shake flasks and stirred bioreactor reached 81.0 mg/L and 71.7 mg/L, respectively.
