Bacteria of the genus Azotobacter synthesize auxins, cytokinins, and GA-like substances, and these growth materials are the primary substance controlling the enhanced growth of tomato.27 These hormonal substances, which originate from the rhizosphere or root surface, affect the growth of the closely associated higher plants. 0000008368 00000 n Agricultural fertilizers are available in solid, liquid as well as in gaseous form for cultivation of plants in farms. It therefore appears that Acetobacter xylinum does not oxidize malate in one step but requires two steps with malate dehydrogenase (EC and oxalacetate decarboxylase (oxalacetate carboxy-lyase, EC as catalyzing enzymes.
