Two small, leaky silos were filled with normal high-moisture corn (HMC), and two with HMC severely infested by Helminthosporium maydis. Counts of mesophilic bacteria, lactobacilli, coliforms, yeasts, and molds were made on corn samples as received and periodically thereafter during 220 days of storage. Temperature and gas levels also were monitored. Sequential changes in the populations of lactobacilli, yeasts, and molds were determined during spoilage of HMC. These population changes were compared on the basis of the variables encountered in the present study as well as with the results of previous studies conducted on normal HMC stored under adequate conditions. Heavy infestation by H. maydis had no appreciable effect on HMC preservation.
两个小的、有渗漏的筒仓装满了普通高水分玉米（HMC），另外两个筒仓装满了被玉米长蠕孢严重侵染的HMC。在接收时以及之后储存220天期间定期对玉米样品进行嗜温细菌、乳酸菌、大肠菌群、酵母和霉菌的计数。同时监测温度和气体水平。在HMC变质过程中确定了乳酸菌、酵母和霉菌种群的连续变化。根据本研究中遇到的变量以及先前在适当条件下储存的正常HMC的研究结果，对这些种群变化进行了比较。玉米长蠕孢的严重侵染对HMC的保存没有明显影响。
