The maximal Monacolin K yield 297.4 mg/L was obtained under the following conditions: glycerin 102.2 g/L,soybean powder 29.2 g/L,NaNO_3 2.0 g/L,MgSO_4·7H_2O 1.0 g/L,KH_2PO_4 1.0 g/L,initial pH 4.5,cultured for 15 d at 26 ℃.
其较佳的工艺条件为:甘油102.2 g/L,黄豆粉29.2 g/L,NaNO32.0 g/L,MgSO4.7H2O 1.0 g/L,KH2PO41.0 g/L,初始pH 4.5,26℃下培养15 d.
There were 4 groups: extracts group with concentration of 0.1, 0.01, 0.001, 0.000 1 g/mL, negative control group (containing nutrient solution at the same concentration to the cell), and dissolvent control group (75 g/L glycerine).
Methods The rabbits of glycerinum groupⅠandⅡwere injected in muscular tissue of one_sided leg with50%glycerinum with dose of5.6ml/kg·bw and10ml/kg·bw,and glycerinum was replaced by equivalent volume of normal saline in normal control groupⅠandⅡ(n=15).
Results It showed that plasma viscosity and fibrinogen(Fib)content of glycerinum groupⅡwere significantly increased than those of glycerinum groupⅠ,control groupⅠandⅡ,and Fib content of glycˉerinum groupⅠwas significantly increased than that of control groupⅠandⅡ(P<0.05).
Separation of 1,3-propanediol from glycerol-based fermentations of Klebsiella pneumoniae by alcohol precipitation and dilution c
The separation of 1,3-propanediol from the glycerol-based fermentation broth of Klebsiella pneumoniae plays an important role during the microbial production of 1,3-propanediol.
The cycle of glycerol feeding, the strategy of methanol feeding and the optimum pH for protein induction were studied.
The optimized strategies were a 4-h glycerol-feeding period, induction pH being kept at 5.0 and methanol concentration being kept under 5 g/L.
The growth of this strain, referred to as 50.3, on a mineral glycerol-containing medium produces an emulsifying activity (60%) and decreases the surface tension of the culture liquid by a factor of 2.8 (to 25 mN/m).
The calculation was made for glycerine with air bubbles.
It is assumed that at pressures up to 400·105 N/m2 glycerine is a linearly elastic medium In this case, the dynamic compression diagram of the two-component glycerine-gas-bubble medium is linear.
The experimental validation of our model was achieved through potential difference measurements of the diffusion potential between two solutions containing sodium chloride (NaCl) and glycerine solutions of various concentrations.
From the point of view of an examination of neutral materials (carbohydrates, glycerine and 2,3-butanediol) in beverages a reliable procedure for categorising and quantitative gas chromatographic analysis of these compounds has been developed.
