During the past few years scattered information has appeared which indicates that at least some bacteria probably possess a tricarboxylic acid cycle. Lockwood and Stodola found that Pseudomonas jluorescens formed considerable quantities of a-ketoglutaric acid when growing on a glucose medium under conditions of intense aeration (1). Ajl and Werkman found evidence for at least parts of the conve...

In the medium used in previous work, both growth rate and maximum cell population density were reduced in protein-free medium. This was due to iron limitation. In a medium supplemented with iron, the average minimum population doubling time was reduced from 78 to 37 h and the average maximum cell population density increased from I-6XIO° to 33 x io°/ml. In the improved medium described, sodium ...

Ester–aldehyde fraction (EAF) is a by-product of ethyl-alcohol-producing companies whose purification requires an expensive process. The results this study illustrate the environmentally friendly and alternative possibility using EAF to increase their value as substrate produce α-ketoglutaric acid (KGA) different yeasts. It was found that some species genera Babjeviella, Diutina, Moesziomyces, ...

Bud dormancy of deciduous fruit trees is a complex process that allows to survive long periods in adverse conditions during winter. Dormancy major obstacle for both production mild winter areas and off-season culture protection facilities. It very economically advantageous be able control the time point bud break consequently harvest crops with high returns short seasons like blueberry (Vaccini...
