The highest resistant temperature, OD value and acid-producing ability of lactobacillus in pickle was measured.

本文以方便廉价的泡豇豆为原料,测定泡菜中的乳酸菌的最高耐受加热温度、OD值和产酸能力,经过温度梯度试验得出泡菜中的乳酸菌的最高耐受加热温度为35~40℃,但是经过高温处理后泡菜中的乳酸菌的OD值差异显著,且产酸能力明显下降。

By using the spectrophotometer we can mensur its OD value.

用分光光度计可以在其最大光吸收波长处测定其OD值。

Under suitable technical conditions,the refined gardenia yellow pigment would be obtained with the colority more than 420,and the OD value less than 0.
