Abstract: The invention provides a simple and effective method for improving acid tolerance of P. acidipropionici by adding arginine and/or aspartic acid to the culture medium. The acid tolerance of P. acidipropionici was improved by 60% and 20% respectively through adding arginine or aspartic acid into the culture medium. Consequently, PA production was improved by 36% and 26%, respectively. The maximal PA production was obtained by adding both 20 mM arginine and 20 mM aspartic acid. This method can be applied to large scale production of PA.

Abstract: Disclosed are methods for increasing microbial catalase production. 1-10 g/L sodium hexametaphosphate was added to the culture medium between 30-40 hours of fermentation to inhibit proteinase activity and increase the production of catalase. This simple modification of fermentation procedure can result in up to 45% increase of the production of catalase.

Abstract: A modeling system and modeling method based on a logical relation, including an operation task integrating module, a task interpreter, a graph layout correcting module, a graph wiring correcting module and a database model increment correcting module, wherein the database model increment correcting module includes a graph increment calculating unit and a model increment calculating unit. The system, through description of the logical relation and based on support of the automatic wiring technology, realizes the graph-model integrated generation of a new grid model of the power system which is based on the description of the logical relation; the grid model is completely defined and modified on “one net”, which is different from the original way that the power system model is established on countless net graphs, thereby helping the grid operation manager to accurately and rapidly establish and modify the grid model of the full system.
