Photodissimilation of fructose to H2 and CO2 by a dinitrogen-fixing cyanobacterium, Anabaena variabilis
Article Abstract:
The cyanobacterium Anabaena variabilis converts fructose to H2 and CO2 in a light-dependent reaction, when incubated in the presence of argon. Hydrogen production depends on the availability of fructose and heterocyst. The production of H2 increases proportionately with fructose concentrations. The efficiency of conversion to H2 is 10 while that to CO2 is 3.5, indicating that a smaller portion of fructose is converted to CO2. Photosystem II also plays a role in the formation of H2.

Degradation pathway and generation of monohydoxamic acids from trihydroxamate siderophore deferrioxamine B
Article Abstract:
Siderophores are virulence factors for plants as well as animal pathogens and the sequestration of iron by the host is an immune mechanism that could limit the course of pathogenic infections. The metabolism of trihydroxamic acid siderophore deferrioxamine B by M. loti goes by a specific actual degradation and represents the reversal by which hydroxamate siderophores are thought to be synthesized.

Determination of Cu environments in the cyanobacterium Anabaena flos-aquae by X-Ray absorption spectroscopy
Article Abstract:
Metals that are non-biodegradable harm the environment and even though membrane-based processes are used to reverse the ill effects it hasn't helped. Experiments have shown that bacteria immobilize metal ions and could be used to reduce the toxic effects on plants, animals and humans.
