Effects of initial carbon source concentration and nitrogen source concentration on D-ribose fermentation and feeding process in flask.

初始碳氮源浓度对d -核糖发酵的影响及摇瓶补料工艺。

To exclude higher oxygen concentration in an equipment with an potential source of ignition we use Nitrogen to dilute the air in the vessel.

避免设备内氧气浓度过高以及火源的存在，使用氮气稀释釜内空气。

The results showed that starch as carbon source, and casein and soybean powder as nitrogen source, o methoxyphenol and vanillin of suitable concentration had good influence on laccase production.

结果表明，淀粉作碳源、干酪素作氮源有利于漆酶的分泌，适宜浓度的愈创木酚和香兰素等对漆酶的产生有一定的作用；
