查询词典 mmol

It was found that 0.25%o potassium sorbate produced a positive inhibition against short G+ spore bacillus with a concentration less than 5xl04cfu/ml. A concentration less than %o potassium sorbate hardly exerted a complete control towards short G- plump bacillus having a population density of 5x104cfu/ml. It was proved that use of l% potassium sorbute never controlled the growth of G+ coccus, G~ spirilla and enterobacter with a population density of 104cfu/ml. 1mmol EDTA completely controlled the growth of G+ short spore bacillus and G+ coccus whose cell density was 5xl04cfu/ml. A level of lmmol EDTA showed a limited inhibition against the growth of G- spirilla with a population density of 105 cfu/ml. However, a level of 10mmol EDTA completely controlled the growth of the G- spiral bacteria having a population density of 105cfu/ml. lOmmol EDTA produced a very significant control towards the growth of G"" plump short bacillus with 105cfu/ml. 20mmol EDTA showed a remarkable inhibition against the enterobacter with a population density of 105cfu/ml. Different concentrations of nisin including 25mg/mL, 50mg/mL, 75mg/mL and 100mg/mL were used as bio-preservative to examine its effects against the growth of all strains leading to the spoilage of fresh mutton meat. It was seen that there was a big difference in nisin's concentrations in inhibiting the spoiling bacteria. Generally speaking, as more as 75mg/mL of nisin significantly inhibited the growth of G+ short spore bacillus, G-plump short bacillus, enterobacter, G'spiral bacteria and G+ coccus having a population density of 105cfu/ml.

分别运用山梨酸钾、EDTA和Nisin对7种主要引起羊肉腐败的微生物进行了抑菌实验，结果显示，0.25‰以上山梨酸钾能够有效抑制5×10~4 cfu／mL以下的革兰氏阳性短芽孢杆菌的生长；1‰以下的山梨酸钾不能完全抑制5×10~4 cfu／mL革兰氏阴性粗短杆菌的生长，对10~4 cfu／mL革兰氏阳性球菌菌株、革兰氏阴性螺旋菌菌株和肠杆菌菌株抑制效果不太明显。1mmoL EDTA能完全抑制住小于10~5 cfu／mL革兰氏阳性短芽孢杆菌菌株、革兰氏阳性球菌菌株的生长，能明显的抑制10~5 cfu／mL的革兰氏阴性粗短杆菌菌株生长，对10~5 cfu／mL的革兰氏阴性螺旋菌菌株有一定的抑制作用。10mmoL EDTA能完全抑制住10~5 cfu／mL革兰氏阴性螺旋菌菌株的生长；能明显抑制10~5 cfu／mL的革兰氏阴性粗短杆菌菌株的生长，而20 mmoL EDTA能很明显抑制10~5 cfu／mL肠杆菌菌株的生长。25mg／mL、50 mg／mL、75 mg／mL和100 mg／mL的Nisin几乎对所有引起羊肉的腐败菌有抑制作用，但抑制程度不同，抑菌活性有一定的变化。

Using Eriochome cyanine R staining, we found that Al accumulation on surface of root tips was positive related to the inhibition of root growth in treatments of 0 - 80μmol·L~(-1) Al for 24 h.
