Abstract

Fifty isolates of fungi were screened for their ability to grow on and degrade sludge. Cunninghamella elegans was selected for further study of degradation as affected by moisture, nutrients, time and temperature. Maximal sludge degradation (total dry weight basis) was 5.8% by Rhizopus oligosporus, 5.4% by C. elegans and 5.3% by Myrothecium verrucaria, representing approximately 11% degradation of the organic matter present. Added nutrients had little or no effect on sludge degradation. Maximal sludge degradation by C. elegans occurred in three weeks at 30-35 C or four weeks at 25 and 40 C.

摘要

对五十株真菌进行了筛选，以检测它们在污泥上生长和降解污泥的能力。选择雅致小克银汉霉进一步研究湿度、养分、时间和温度对降解的影响。少孢根霉对污泥的最大降解率（以总干重计）为5.8%，雅致小克银汉霉为5.4%，疣孢漆斑菌为5.3%，这大约相当于所存在的有机物的11%被降解。添加养分对污泥降解几乎没有影响。雅致小克银汉霉在30 - 35摄氏度下三周或在25和40摄氏度下四周时对污泥的降解达到最大值。
