Approaches to address
hydrogenase O-sensitivity barrier- Problem:
Cyanobacteria have the ability to split water photolytically
into 02 and H2, but their hydrogenases are highly 02-sensitive. In
contrast, certain bacteria have 02-tolerant H2-evolving hydrogenases,
but they can not use water as the electron donor.- Approach:
transfer 02-tolerant hydrogenases into cyanobacteria
1. Identifying novel 02-tolerant hydrogenases from VI's
sampling in international waters and transferring them
into cyanobacteria
2. Transferring known 02-tolerant hydrogenases into
cyanobacteriaJ. Craig
