Eight bacterial strains utilizing glucoisosaccharinic acid (GISA), which is one of the main components of sulphate black liquor hydroxyacids, were isolated from the environment of a sulphate pulp mill. The best GISA‐utilizing bacterium was isolated from soil and it was identified as Micrococcus lylae . The growth of M. lylae on GISA in the pH range 5.0–9.0 was studied, optimum growth and utilization of GISA being observed at pH 8.0. M. lylae also utilized D,L‐lactic acid and black liquor separated from the lignin.
