TI  - Effect of carbon substrates on rock phosphate solubilization by bacteria from 
      composts and macrofauna.
PG  - 298-302
AB  - Five of the 207 isolates from different composts, farm waste compost (FWC), rice 
      straw compost (RSC), Gliricidia vermicompost (GVC), and macrofauna, showed rock 
      phosphate (RP) solubilization in buffered medium in plate culture. When tested in 
      RP broth medium, all five strains, Enterobacter cloacae EB 27, Serratia 
      marcescens EB 67, Serratia sp. EB 75, Pseudomonas sp. CDB 35, and Pseudomonas sp. 
      BWB 21, showed gluconic acid production and solubilized RP. Based on 
      cellulose-degrading and P-solubilizing ability, two strains were selected for 
      further studies. In the presence of different carbon sources, both strains showed 
      a drop in pH and solubilized RP. P released was maximum with glucose (1212 and 
      522 micromol) and minimum with cellobiose (455 and 306 micromol) by S. marcescens 
      EB 67 and Pseudomonas sp. CDB 35, respectively. Glucose dehydrogenase (GDH) 
      activity was 63 and 77% with galactose and 35 and 46% with cellobiose when 
      compared to glucose (100%) by EB 67 and CDB 35, respectively. Both strains 
      solubilized RP in the presence of different crop residues. EB 67 and CDB 35 
      showed maximum cellulase activity (0.027 units) in the presence of rice straw and 
      a mixture of rice straw and root. P solubilized from RP in the presence of 
      pigeonpea root was 134 and 140 micromol with EB 67 and CDB 35. Significantly, 
      these bacteria isolated from composts and macrofauna solubilized rock phosphate 
      in the presence of various pure carbon substrates and crop residues and their 
      importance in soil/rhizosphere conditions is discussed.
