摘要

A novel Lactobacillus clearans, Lactobacillus sulfurica and Lactobacillus nitrosus: which can decrease both Na2S.9H2O and/or NH3 when inoculated and cultured on: a medium comprising 5 g of meat extract, 5 g of peptone, 0.5 g of Na2S.9H2O, 5 g of glucose, 1 g of CaCO3, 0.5 ml of NH3 (as 100% ammonia) and 1 liter of water (pH, neutral); which shows no growth acceleration action even when said bacteria is cultured on a medium comprising a Stephenson-Wetham medium (hereafter merely referred to as (S-W); KH2PO4 1 g, MgSO4.7H2O 0.7 g, NaCl 1 g, (NH4)2HPO4 4 g; FeSO4.7H2O 0.03 g, glucose 5 g)+vitamins (A: 900 IU, B1: 1 mg, B2: 1 mg, B6: 1 mg, B12: 5 gamma nicotinamide: 1.6 mg, calcium pantothenate: 8 mg, C: 64 mg, D2: 120 IU)+casamino acid 1 g and 0.5 g of Na2S.9H2O and/or 0.5 ml (100% conversion) of NH3 are incorporated at the logarithmic growth phase; and; which has the following characteristics: gram-positive, rod, non-motile, catalase-negative, no reduction of nitrates, no decomposition of gelatin, no formation of indole or hydrogen sulfide, high ability of forming lactic acid from glucose and lactose, and growth being accelerated by the addition of acetic acid.
