发现枯草芽孢杆菌孢子主要成分的磺酸被暂时鉴定为3-L-磺基乳酸。这种化合物在生长过程中完全不存在于营养细胞中，但在折射孢子发育之前在孢子细胞中大量积累。基本上所有积累的磺基乳酸最终都融入到天然孢子中，可能占孢子干重的 5% 以上。发芽导致未改变的磺基乳酸快速且完全释放到培养基中。在巨大芽孢杆菌、蜡状芽孢杆菌或 B. 的孢子中未发现该化合物。苏云金。
A sulfonic acid found to be a major constituent of spores ofBacillus subtiliswas provisionally identified as 3-l-sulfolactic acid. This compound was completely absent from vegetative cells during growth, but large amounts accumulated in sporulating cells just before the development of refractile spores. Essentially all of the accumulated sulfolactic acid was eventually incorporated into the nature spore, where it may represent more than 5% of the dry weight of the spore. Germination resulted in the rapid and complete release into the medium of unaltered sulfolactic acid. This compound was not found in spores ofBacillus megaterium, B. cereus, orB. thuringiensis.
