Effects of Amino Acids on Cellulose Production in Defined Medium by Acetobacter xylinum

doi:10.7506/spkx1002-6630-201109046

Abstract

Abstract: A total of 18 amino acids were added respectively into the defined medium for Acetobacter xylinum to determine their effect on the cellulose yield. Based on the production of cellulose, these amino acids were divided into three categories: high-yield (7), low-yield (9) and zero-yield (2). In addition, the respective formulation of 7 high-yield and 9 low-yield amino acids was investigated using orthogonal array design. It was found that histidine was the optimum nitrogen source in the defined medium among these 18 amino acids, but inferior to ammonium sulphate. Coexisting histidine and ammonium sulphate could be utilized without undesirable interaction.

Key words: amino acids, Acetobacter xylinum, defined medium
