2024/5/1/ · The activities of CMCase, β-Gase and FPase were detected at 0.365 U/g, 0.115 U/g and 0.096 U/g on day 0 of composting. As shown in Fig. 2 b, the activities of CMCase and FPase activity were rapidly increased until the turnover of the compost (76 days). Initially, β-Gase was improved with a reduction of CMCase and FPase, which was
2023/12/12/ · Composting requires a certain balance of carbon-rich materials (“browns”), such as dry leaves and untreated wood chips, to nitrogen-rich materials (“greens”), such as food scraps. The ideal ratio is roughly three parts browns to one part greens by volume. (This translates to roughly 30:1 in terms of elemental carbon to

Besides, pH value also affects the loss of nitrogen, so when the pH value is over 7.0, nitrogen will volatilize in the form of ammonia. However, as a significant factor in composting process and quality, pH value ranging from 6.0-7.5 is fit for bacterial development while ranging from 5.5-8.0 is suitable for fungi growth.
When comparing the different aeration rates of these two distinct composting , they tend to be characterized by large differences in temperature and O 2 content, which substantially influences the fate of microorganisms and the quality of the compost produced (Onwosi et al., 2017). However, existing studies mainly focus on the degassing
