Method of improving biomass yield of lactic acid bacterial cultures

A method of enhancing biomass yield of a lactic acid bacterial species cell culture, comprising cultivating the cells in a process comprising the steps of providing conditions that results in a reduced glycolytic flux and providing conditions that enable the cells to have, under aerobic conditions, a respiratory metabolism. The increased yield of biomass may be the result of an increased yield of ATP which can be obtained by activating the native ATP synthase activity of the H+-ATPase complex by lowering the ATP / ADP ratio, e.g. by carbon source limitation, and / or by increasing the proton gradient (membrane potential) of the cells, e.g. by enhancing or establishing an electron transport chain which can be achieved by enhancing expression of dehydrogenases or electron transport chain components, by adding to the medium a quinone or porphyrin compound or by enhancing the expression of the H+-ATPase activity.

Application of Nano-MitoPBN in preparing medicines for resisting oxidation and treating diabetes

The invention belongs to the technical fields of biology and medicine, and particularly relates to application of Nano-MitoPBN in preparing medicines for resisting oxidation and treating diabetes. Dueto the micro-compartmentalization effect, Nano-MitoPBN can remove mitochondrion superoxide / hydrogen peroxide generated by single electron leakage of a liver mitochondrion electron transport chain, increase the respiration rate of a mitochondrion state 3 and the respiration control ratio, improve synthesis of ATP, and promote the function of mitochondria. In addition, by reducing ROS, Nano-MitoPBNreduces gluconeogenesis, increases glycolysis, reverses ROS-mediated liver glycometabolism reprogramming in diabetic animals, then reduces the peripheral blood glucose level of the diabetic animals and restores the glucose tolerance of the diabetic animals. Nano-MitoPBN serves as a material for preparing the medicines for treating diabetes, can be used for targeting liver prevention and relievingand treating diabetes, and can obtain a remarkable curative effect with a very small dosage.
