Bacteria, yeasts, and molds isolated from partially processed iceberg lettuce were taxonomically classified. The majority of bacterial isolates were gram-negative rods. Pseudomonas, Erwinia, and Serratia species were commonly found. Yeasts most frequently isolated from lettuce included members of the genera Candida, Cryptococcus, Pichia, Torulaspora, and Trichosporon. Comparatively few molds were isolated; members of the genera Rhizopus, Cladosporium, Phoma, Aspergillus, and Penicillium were identified.
对从部分加工的卷心莴苣中分离出的细菌、酵母和霉菌进行了分类学鉴定。大多数分离出的细菌为革兰氏阴性杆菌。常见的有假单胞菌属、欧文氏菌属和沙雷氏菌属。从莴苣中最常分离出的酵母包括念珠菌属、隐球菌属、毕赤酵母属、球拟酵母属和丝孢酵母属的成员。分离出的霉菌相对较少;鉴定出了根霉属、枝孢属、茎点霉属、曲霉属和青霉属的成员。
