The invention relates to a method for extracting oxygen form a reaction chamber, as well as a use of microorganisms in such a method and a photobioreactor for carrying out the method.

According to the invention, the method comprises the steps—irradiating at least one phototropic microorganism with light under anaerobic conditions in a reaction chamber, and—in situ bonding of produced oxygen by means of the microorganism by oxidation of an oxygen-utilizing substrates.

Disclosed are purified proteins, cell lysates, cell-free extracts, and protein extracts comprising 1-hexene monooxygenase (1-HMO) and methods of their use for delaying plant development.

The present disclosure provides recombinant bacteria with elevated production of ethanol and/or n-butanol from ethylene. Methods for the production of the recombinant bacteria, as well as for use thereof for production of ethanol and/or n-butanol are also provided.
