Linear relations among net conversion rates of primary metabolites in fermentation processes can be determined by using the macroscopic or pathway balancing methods. It is shown that the process observability can be improved by incorporating both the abiotic proton balance and the pH control reagent

โฆ Synopsis
A new description of the pH-auxostat is obtained by using the abiotic proton balance in the mathematical model. The new model shows how the stoichiometry of metabolism affects the steady-state and stability characteristics of the pH-auxostat. The model can also be used to determine the amount of ammonium salts to include in the medium, and can be applied to the pH-stat modal fed-batch reactor and the bistat.

Saccharomyces cerevisiae contains three chitin synthetases, Chs1, Chs2, and Chs3, performing different physiological functions but catalyzing the same reaction. It has been found that Ni2+ is a powerful inhibitor of Chs1 and Chs2 activity but has very little effect on the activity of Chs3, especiall
Large bottomless lysimeters were investigated for their suitability as a tool in the study of water balances of treeless and tree-covered areas on a raised mire. The lysimeters, large enough to contain a mature tree, were developed to measure the liquid discharge from the peat monolith they enclosed
