To investigate the feasibility of microbial pre-decomposition of timber wastes to quality production of vermicompost with higher agronomic value, timber wastes were inoculated with different combinations of the fungi Phanerochete chrysosporium, Trichoderma reesei, Aspergillus niger and the bacteria Azotobacter chroococcum (MTCC 3853) and Bacillus cereus (MTCC 4079) and incubated at 28-30 °C in a mechanical composter. The inoculation enhanced the degradation of timber wastes, increased total nitrogen and improved the quality and enhanced production of vermicompost generated with the native earthworm Drawida willsi Michelsen. Total nitrogen increased from 0.16% to 1.52% and total organic carbon (TOC) decreased from 42% to 13%. Out of 10 microbial combinations tested for pre-decomposition, the combination of P. chrysosporium+T. reesei was found best in terms of ligno-cellulosic decomposition, and P. chrysosporium+A. niger+B. cereus with respect of cast output. The study shows that microbial pre-decomposition of timber wastes to produce quality vermicompost is a feasible technology.
为了研究微生物预先分解木材废料以生产具有更高农艺价值的高质量蚯蚓粪的可行性，将不同组合的真菌黄孢原毛平革菌、里氏木霉、黑曲霉和细菌固氮菌（MTCC 3853）和蜡状芽孢杆菌（MTCC 4079）接种到木材废料中，并在 28-30°C 的机械堆肥机中进行培养。接种增强了木材废料的降解，增加了总氮，并改善了用本地蚯蚓 Drawida willsi Michelsen 产生的蚯蚓粪的质量和产量。总氮从 0.16%增加到 1.52%，总有机碳（TOC）从 42%减少到 13%。在测试的 10 种微生物预分解组合中，P. chrysosporium+T. reesei 在木质纤维素分解方面表现最佳，而 P. chrysosporium+A. niger+B. cereus 在铸件产量方面表现最佳。研究表明，微生物预先分解木材废料以生产高质量的蚯蚓粪是一种可行的技术。
