0.0067g/mL Sodium glutamate and 0.0033g/mL KIwould improve the oxygen tolerance of the AGS, while 0.0033g/mL Na2S and 0.0067g/mL vitamin C and 0.0033g/mL NaHSO3 would restrain the oxygen tolerance of the AGS.
The Plackett-Burnam design was applied to screen out the key factors from the following eleven components, namely, glucose, sucrose, corn syrup powder, peptone, soybean bud juice, KH2PO4, Na2HPO4, MgSO4, ZnSO4·7H2O, VB1 and sodium glutamate, which would affect the mycelium growth and extracellular polysaccharides excretion of Ganoderma lucidum.
Results:Results showed under the condition of 50μM sodium glutamate (GLU), 50-1000μM TPM could increase the survival rate of neuron from 30.9% to 40.4-71.9%;
When 70 g/L of sucrose,50 g/L of tryprone,30 g/L of NaCl and(26.6%)(v/v) of unrefined raw material(120 g/L of sodium glutamate) were added to the media(pH7.0),CGMCC No. 1250 was cultivated at 37℃,220 r/min,for 24 hours,the productivity of γ-PGA reached 41.7g/L.
The repeated batch fermentations were conducted (every 96 hours) using the optimized alginate beads, employing the production medium with 3% wt/vol maltose and 0.6% wt/vol sodium glutamate along with minerals salts solution.
The effect of maltose (4%, 3%, 2%, and 1% wt/vol) and sodium glutamate (0.6%, 0.3%, 0.15%, and 0.075%) wt/vol) concentration on neomycin production was also studied.
The responses were identified from their latent and refractory periods, the presence of summation, and the dependence of the firing index on sodium glutamate application to the recorded neuron.
Many investigators gave different opinions on the question whether the increase of the ammonia content of brain is the cause or effect in the course of the convulsion.In the present paper,the experiments show the ammonia con- tent of different regions of the brain in the convulsive rats was markedly in- creased.When sodium glutamate and strychnine were injected intraperitoneally simultaneously,convulsion happened as usual in spite of the decrease of the brain ammonia content except for diencepha...

Piperine and its derivatives (Antiepilepsirine, 7302, 7306, 7446, 7448) belong to a new class of anticonvulsants. In doses less than TD_(50) they were found to be able to protect rats and mice from seizures produced by maximal electroshock, metrazol, picrotoxin, strychnine, tubocurarine and sodium glutamate, and reduce the mortality of animals to various extends. They appeared to have a wide anticonvulsive spectrum. Their action resembled diphenylhydantoin (DPH) in protecting rats and mice from ...
