Formation of α-keto acids from amino acids using immobilized bacteria and algae

  • Published:
Biotechnology Letters Aims and scope Submit manuscript

Summary

Both free and immobilized cells of the algae Chlorella vulgaris and Anacystis nidulans contain aminoacid oxidase (AAO) activity which is increased by illumination with red light. Both immobilized species are photosynthetically active. By co-immobilizing Chlorella with bacterial cells (Providencia sp. PCM 1298) containing high AAO activity an increased production of keto acid (up to tenfold) is observed due to improved oxygen supply.
