title: [Physiological and biochemical activity of bacteria during germination of cucumber seeds and impact of ciliates Colpoda steinii on this process].
abstract: It is shown that the bacteria Bacillus subtilis B-7023 IMV produce indole-3-acetic acid and amino acids in the liquid medium Knoop. Processing cucumber seed suspension containing 10(7) cfu/ml as bacilli, and Azotobacter vinelandii IMV V-7076, resulted in a decrease in the length of the roots of plants. Reduction of bacterial load bacilli to 10(6) cfu/ml followed by reduction of indole-3-acetic acid in the medium, and to an increase in the length of roots, shoots and total plant mass. During the cultivation of Bacillus subtilis IMV V-7023 with ciliates Colpoda steinii reduced the amount of free forms of auxin in the medium to 5.5 times, and the related--to trace amounts. The content of histidine, phenylalanine, tyrosine, methionine and lysine significantly reduced.
