Tetracoccus soyae nov. sp. Ueno and Omata was isolated in 1961 from Soy-sauce mash (Ueno, Omata, 1961) and is regarded as halo-tolerant, gram-positive, catalase-positive and tetrad-forming cocci which is considered to be facultative anaerobic and members of the family Lactobacillaceae.When grown in rich carbohydrate media under static condition, this organism is known to exhibit a homolactic fermentation pattern.There is little information available on the metabolism of this organism. The present investigation was undertaken to study the metabolism of aerobic degradation of glucose in this organism.When grown in rich carbohydrate media under shaking culture, this organism exhibited a gluconic acid fermentation pattern. This penomena resembles the gluconic acid formation of Ped. pentosaceus. (Dobrogosz, Demoss, 1963)But in this case, gluconic acid formation was observed in the presence of 10% NaCl. Maximum yield was 73% based on consumed glucose from 20% glucose media in the presence of 2% NaCl.
