Effects of low-temperature alkali urine pretreatment on microbial diversity during continuous anaerobic fermentation of maize straw during methane production
The effects of alkali urine pretreatment on anaerobic microbial diversity were determined by analyzing the microbial changes after fermentation at 6% and 10% feed concentrations under the condition of 7%/12% NaOH/urea solid-liquid ratio of 1:1
