The Ecology and Classification of Strains of Lactobacillus collinoides nov. spec.: A Bacterium Commonly Found in Fermenting Apple Juice

S ummary : Most heterofermentative lactic rods occurring throughout the cider industry are quite similar and form a fairly coherent group. The constituent bacteria are sufficiently different from other heterofermentative lactobacilli to be considered a new species. They have, therefore, been named Lactobacillus collinoides nov. spec. These occur most frequently in factories where sulphur dioxide, the only permitted preservative, is either used in small quantities or not at all.
