Cyanobacterial biofilms: from natural systems to applications: Trends in Biotechnology

[Michael Hayes]

"Highlights

As solar cell factories, cyanobacteria generate value-added compounds directly from CO2 and sunlight, opening the field of photobiotechnology for carbon-neutral or carbon-negative production scenarios.

Cyanobacterial biofilms are superior to suspended cell cultures in robustness, turnover numbers, and cell densities.

Cyanobacterial biofilms are applied in diverse fields, from agriculture to wastewater treatment and bioremediation to the production of value-added compounds and biofuels."

MH] Oceanic deserts are likely ideal for using floating mats for mCDR and SRM related resource and services. Blocking solar energy over wide oceanic deserts using floating mats, while harvesting nitrogen, carbon, sulfur etc, would seem to offer a rapid scale up potential that might pay for itself in the short-term.
