This study estimated the effects of 0.5–1.5% lime and 10% calcium magnesium phosphate fertilizer (CaMgP) addition (dry mass) on maturity, gaseous emissions, bacterial dynamics during food waste composting. The 1.0% 1.5% amendments accelerated proliferation Thermobifida Saccharomonospora for a higher germination index. growth methanogens (Tepidimicrobium Caldicoprobacter) Bacillus was restrained by additives to reduce methane (CH4) ammonia (NH3) respectively.

Turning over fermented grains is widely used during the heap fermentation of sauce-flavor baijiu to increase temperature, however, effect turning on still unclear. The present study investigated changes microbial community structure and volatile compounds before after by using high-throughput sequencing combined with gas chromatography-mass spectrometry (GC-MS). Firstly, lead a redistribution acidity moisture content in different layers an temperature. Secondly, total 41 were identified, among which concentrations ethanol, phenylethyl alcohol, acetic acid, ethyl-9,12-octadecadienoate elevated over. Next, parameters altered or enhanced their driving effects succession, resulting reducing relative abundance Pediococcus, Aspergillus, Thermoascus Thermomyces, while boosting Lactobacillus Issatchenkia making these two members as predominant genera. bio-heat generated succession contributed rapid continues These results provided basis for understanding intrinsic mechanism traditional brewing process baijiu.
