Abstract

α-Glucoisosaccharinic acid (GISA), a major byproduct of kraft paper manufacture, was synthesized from lactose and used as the carbon source for microbial media. Twenty-seven laboratory strains of bacteria were tested and none was capable of growth on GISA. GISA degrading isolates were not found in forest soils. Ten aerobic bacterial strains capable of growth on GISA were isolated from kraft pulp mill environments. Highest growth yields were obtained with Ancylobacter ssp. at pH 7.2 to 9.5. GISA was completely degraded by cultures of an Ancylobacter isolate. Ancylobacter cell suspensions consumed oxygen and produced carbon dioxide in response to GISA addition.
