Abstract |
: |
Was isolated from the isolation of 154 isolates Alastervtomiss clean soil contaminated with petroleum waste from urban areas of industrial residues and contaminated soil sanitation. And these isolates were isolated from each of the plants Raazausver Cyperus conglomeratum 'Hamada elengans, Leptadenia pyrotechnica, Blepharis ciliaris. Purification of the isolates were using the usual methods of mitigation, and through examination of farms and microbial metabolic and physiological activity has been selected the 12 isolated capable of growth in the community food containing heavy metals selected for study. And studied the physiological properties of these isolates, which includes the right conditions for the growth of isolates and their ability to produce antibiotics and pigments are dissolved. Was identified on the criteria of growth. These isolates did not register any significant differences when their development in the center GYM liquid food and life values ranged between generation -8.51 7.35 an hour. And development of selected isolates in the center containing the heavy elements found that the rate of growth Specialist decrease increase concentration of these elements, and the back of the production of antibiotics without influenced by these elements until the concentration of 100 ppm, while the production of dyes dissolved has shown that the color purple has started to decline after the concentrate 100 ppm for the three elements tested, and isolation of pigment-producing pink affected by all the heavy metals tested, 200 ppm, while the isolates increased the production of red pigments Obbaghma increasing concentration of zinc and yellow dyes isolates differed among the four isolates and the effect of each element. And it is considered to be influenced by varying the amount of the elements of all three isolates, both in the rate of growth specialist, the production of antibiotics, dyes, or the activity of each element is different from the other. In terms of bio-assembly has been found that isolation of pigment-producing isolates of the best Rose in the dynamic assembly of the heavy elements and found that the isolation of pigment-producing radiation isolates were of the best in the bio-absorption of heavy elements. |
