Gallic Acid Production by Immobilization of Aspergillus orzae.

  title={Gallic Acid Production by Immobilization of Aspergillus orzae.},
  author={N. Lokeswari},
Gallic acid (3,4,5 trihydrixybenzoic acid) is an organinc substance occuring in many plants either as a free molecule or as part of tannic acid molecule. Production of gallic acid using the immobilized cells of Aspergillus oryzae has been studied. It was observed that 12% tannic acid concentration, 200 numbers of calcium alginate beads of spore concentration 2 x 105/ml and initial pH 5.5 gave the maximum gallic acid production. The % of tannin conversion was 78.5% whereas in free cell culture… Expand
