Co-culture of a Novel Fermentative Bacterium, <i>Lucifera butyrica</i> gen. nov. sp. nov., With the Sulfur Reducer <i>Desulfurella amilsii</i> for Enhanced Sulfidogenesis.

ABSTRACT: Biosulfidogenesis can be used to remediate low pH and high metal content waters such as acid mine drainage and recover the present metals. The selection of a cheap electron donor for the process is important for the economic viability. In this work we isolated a novel versatile acidotolerant fermentative bacterium (strain ALE^T) that is able to use a great variety of substrates including glycerol. Strain ALE^T is an obligate anaerobe, and cells are motile, rod-shaped, spore-forming, and stain Gram-positive. Growth occurred in a pH range from 3.5 to 7 (optimum 5.5), and temperature range from 25 to 40°C (optimum 37°C). It grows by fermentation of sugars, organic acids and glycerol. It has the ability to use thiosulfate, iron and DMSO as electron acceptors. Its genome is
