B. Gupta R",aparna,"shanker et al., SOLUBILIZATION OF LOW-GRADE INDIAN ROCK PHOSPHATES AND INORGANIC PHOSPHATES BY BACILLUS-LICHENIFORMIS, Folia microbiologica, 38(4), 1993, pp. 274-276
Bacillus licheniformis solubilized a range of inorganic phosphates and
five different Indian rock phosphates (low grade) to varying extent i
n broth culture and in soil. Statistical evaluation indicated that bro
th cultures alone were inadequate indicators of the potential for micr
obial solubilization of rock phosphates.
