Kinetics of Invertase Production by Saccharomyces Cerevisiae in Batch Culture
The present study is concerned with the improved invertase production by Saccharomyces cerevisiae on kinetic basis. The wild-culture (IIB-1) and putative mutant (NA6) of S. cerevisiae were compared on time course basis when grown in batch culture. The values for Yx/s, Yp/s and Yp/x with urea were significantly improved (p≤0.05) over the control (peptone+yeast extract) as well as peptone supplem...
متن کاملProduction of Recombinant Human Granulocyte-Colony Stimulating Factor by Pichia pastoris
Human granulocyte-colony stimulating factor (hG-CSF) cDNA was expressed in the methylotrophic yeast Pichia pastoris under the control of the alcohol oxidase (AOX1) promoter. An expression vector for hG-CSF secretion was constructed using vector pPIC9. Higher levels of hG-CSF was obtained using a P. pastoris Mut+ (methanol utilization fast) phenotype. The effects of environmental factors such as...
متن کاملTHE ROLE OF ALVEOLAR MACROPHAGES IN THE PRODUCTION OF COLONY –STIMULATING FACTOR BY THE LUNG
The role of alveolar macrophages in the production of granulocyte/ macrophage colony-stimulating factor(s) by the rat lung was investigated. Lavaged lungs, when incubated at proper weight per volume of culture medium, produced the same amount of colony-stimulating factor as unlavaged ones. Both lavaged and unlavaged lungs produced similar types of colony-stimulating factor (s). Prolonged i...
متن کاملTHE EFFECT OF THEOPHYLLINE ON THE PRODUCTION OF COLONY STIMULATING FACTOR (CSF)BY THE LUNG
The effect of theophylline on colony stimulating factor production by the lung tissue was investigated. Addition of various concentrations of theophylline to the lung conditioned medium enhanced CSF production at 10 µg/ml and at higher concentrations showed an inhibitory effect. Determination of the phosphate content of the medium showed a decrease at 1-3 hours of incubation. Addition of A...
متن کاملProduction of extracellular and total invertase by Candida utilis, Saccharomyces cerevisiae, and other yeasts.
Some strains of Candida utilis produce exceptionally large amounts of extracellular and total invertase. Strain Y-900 of C. utilis produces high yields whether the carbon source is sucrose, glucose, maltose, or xylose and still higher yields with lactic acid, glycerol, and ethyl alcohol. Approximately 20 to 30% of the total invertase of C. utilis is extracellular. Strains of Saccharomyces cerev...
