Comparative analysis on Corynebacterium glutamicum transcriptome in response to the change of dissolved oxygen in bioreactor

Purpose: dissolved oxygen (DO) level is an important factor that could significantly influence microorganisms’ growth, maintenance, metabolism and product yield. The goals of this study are to do comparative analysis on Corynebacterium glutamicum transcriptome in response to the change of dissolved oxygen in bioreactor, find the critical pathways and genes. Method: three batches of fermentation were conducted with different DO level separately (50%, 30%, 0%), and sampled on 20h of fermentation, the transcriptome of Corynebacterium glutamicum generated using Illumina hiseq 2000.
