Humic Acid Biosynthesis and Bacterial Community Evolution during Aerobic Composting of Rice Straw
In this work, the effects of inoculum size, substrate meshes and aeration rate on humic acid (HA) biosynthesis during aerobic composting of rice straw were investigated, respectively. To clearly clarify the changes of microbial community structure involved in the process of composting, the 16S DNA sequences in these samples from 0 day (M01), 10th day (M02), 22nd day (M03) and 36th day (M04) under the optimal operating parameters of Humic acid biosynthesis were sequenced using Illumina MiSeq Sequencing.
