I haven’t seen a detailed list like this on abiogeneses. Most of the research looks at replication or metabolism. This ties both together for the first time.

Using selective pressure, a team from University of Massachusetts Amherst has evolved a strain that forms a thinner biofilm.

Still the rest are typical of his environmental record.

How it’s done is by denitrogenzing bacteria taking nitrates from the water and creating nitrogen gas. And the amount of nitrates in the water is related to the amount made into gas. This relates to algal blooms that is harmful to humans and create dead zones in the ocean.

International Rivers, a NGO, is having action for rivers, today and tomorrow.

Since we only know an infinitesimal number of microbes and know a even smaller amount very well(having mapped their genomes or have been using them in the lab), this seems like a no brainer. NASA is looking for microbes in the lakes of the Antarctic.
