Stories & events

My group is focused on understanding the ways different photosynthetic organisms have adapted their photosynthetic biochemistry and physiology to efficiently fix CO₂ in environments where CO₂ is a limiting substrate. This includes interests in the biochemical deficiencies of Rubisco (where I started in my PhD), how organisms have developed CO₂ concentrating mechanisms (my first postdoc) to overcome these limitations, and how the biochemical pathway of photorespiration deals with the waste products of the Rubisco interaction with O₂. We use organisms ranging from cyanobacteria and algae up the plant model systems such as Arabidopsis, spanning different evolutionary scales of photosynthetic development.

Water and sunlight the formula for sustainable fuel

Story | Thursday 21 August 2014

“Water is abundant and so is sunlight. It is an exciting prospect to use them to create hydrogen, and do it cheaply and safely,” said Dr Kastoori Hingorani, from the ARC Centre of Excellence for Translational Photosynthesis in the ANU Research School of Biology.
