  • Biochemical responses to osmotic stress in cyanobacteria
  • Signal transduction in cyanobacteria under environmental stress
  • Polyamines metabolism in cyanobacteria
  • Amino acids transport in cyanobacteria
  • Biotechnology utilizing cyanobacteria as starting materials
    • Biohydrogen as alternative biofuels
    • Bioethanol and biodiesel production

    • GABA production
    • Bioplastic production to replace petroleum-based plastic

The main research area in Laboratory of Cyanobacterial Biotechnology is listed as described above. We have been studying the mechanism of salinity tolerance in cyanobacteria. In particular we are interested in proteins and/or genes that can confer salt tolerance in cyanobacteria. We have also studied the effect of salt stress on changes of polyamines as well as changes in nitrogen metabolism in cyanobacteria. We also initiated another line of study on signal transduction using cyanobacteria as a model system, i.e. the mechanism(s) involved in phosphate-sensing system.

Recently, we have studied biohydrogen production from different cyanobacteria and green algae. We also tried to genetically engineer the cells to maximize hydrogen production. Production of other renewable energy sources, namely bioethanol and biodiesel is also being investigated. During the past few years we have been working on the induction of UV-absorbing compounds by UV radiation as well as the production of GABA and bioplastic (PHB). Most of the research funding for our group is provided by the Thailand Research Fund,  Chulalongkorn University, and the Commission of Higher Education. At present, Dr. Aran is serving on editorial board of BMC Microbiology as well as Frontiers in
