title: [Bacterial strain characterizing by EDTA requirement].
abstract: A novel strain of bacteria (LPM-4) was isolated that is characterized by a unique EDTA requirement for cell growth. Suspensions of washed cells of strain LPM-4 degrated EDTA complexes with Ba2+, Mg 2+, Ca2+, and Mn2+ at constant rates (0.310-0.486 mmol EDTA/(g h)) and Zn-EDTA at an initial rate of 0.137 +/- 0.016 mmol EDTA/(g h). The temperature optima for cell growth and EDTA degradation were determined under pH-auxostat cultivation. As compared with the known EDTA-degrating bacteria, strain LPM-4 exhibited a higher specific growth rate (0.095 h(-1)) and lower mass cell yield (0.219 g cells/g EDTA) that is promising for its practical applications for EDTA removal in wastewater treatment plants.
