title: [Phosphate-mobilizing bacteria isolated from sediments of Dofinivskyi Lyman and Odessa region of north-western part of the Black Sea].
abstract: Active strains of phosphate-mobilizing bacteria were isolated from sediments of Odessa region of northwestern part of the Black Sea (NWBS) and Dofinivskyi Lyman. Two strains of bacteria were characterized by the highest activity among the selected isolates. Their morphological and physiological-biochemical properties, their genus identity and growth dynamics in a nutrient medium with insoluble calcium phosphate have been investigated. It has been established that the logarithmic phase of bacterial growth began after 6 hours of cultivation. The number of cells after 2 days of cultivation increased from 10(5) - 10(6) to 10(8) - 10(9) CFU cm(-3). This was accompanied by a decrease in pH from 7.1 to 4.56-4.86. The studied bacteria from Odessa region NWBS, identified as Enterobacter sp. 18, accumulated in the culture medium up to 240 mg PO+4(3-)/l and from Dofinivskyi Lyman - Bacillus sp. 5 - 460 mg PO4(3-)/l.
