Rate Of Accumulation

The aerobic lactate production of rat thymocyte suspensions incubated at 37 °C for 2 hours was doubled following exposure to approximately 70 r X-radiation. Lower doses down to 18 r also produced a significant increase in aerobic lactate production. Increased lactate accumulation following exposure to 1000 r was observed after incubation for as little as 30–60 minutes, though the rate of accumulation increased still further between 2 and 4 hours incubation. A decrease in pH or temperature during incubation of irradiated thymocyte suspensions minimized the lactic acid accumulation. A comparison of the effects of X-irradiation in different media and of the effects of several metabolic inhibitors suggested that the increase in aerobic lactate production was a sensitive indicator of cell damage associated with the loss of intracellular potassium ions.Respiration and anaerobic glycolysis of the thymus cells were both much less sensitive than aerobic glycolysis to the effects of X-irradiation. The "anaerobic" lactate production of rat thymocyte suspensions in the presence of dinitrophenol was reduced by 50% after exposure to 5000–6000 r of X-radiation.

Fermentation Parameters

The aim of this study was to gain deeper insights into the dynamics of fermentation parameters and the bacterial community during the ensiling of high-moisture alfalfa. A commercial lactic acid bacteria (YX) inoculant was used as an additive. After 15 and 30 days of ensiling, the control silage (CK) exhibited a high pH and a high concentration of ammoniacal nitrogen (NH3-N); Enterobacter and Hafnia-Obesumbacterium were the dominant genera. At 60 d, the pH value and the concentration of NH3-N in CK silage increased compared with 15 and 30 d, propionic acid and butyric acid (BA) were detected, and Garciella had the highest abundance in the bacterial community. Compared with CK silage, inoculation of YX significantly promoted lactic acid and acetic acid accumulation and reduced pH and BA formation, did not significantly reduce the concentration of NH3-N except at 60 d, and significantly promoted the abundance of Lactobacillus and decreased the abundance of Garciella and Anaerosporobacter, but did not significantly inhibit the growth of Enterobacter and Hafnia-Obesumbacterium. In conclusion, high-moisture alfalfa naturally ensiled is prone to rot. Adding YX can delay the process of silage spoilage by inhibiting the growth of undesirable microorganisms to a certain extent.
