Polyacrylamide added as a nitrogen source stimulates

In those microcosms that contained polyacrylamide, it was added as the sole-fixed nitrogen source to give a carbon:nitrogen mass ratio of 20:1. These serial transfers diluted the amount of fixed nitrogen that accompanied the inocula, ultimately leaving polyacrylamide as the most abundant source of fixed nitrogen in the microcosms.

Biodegradation of Polyacrylamide and Its Derivatives

Although polyacrylamide (PAM) and its derivatives have many useful applications, their release in nature can have impacts on the environment and human health, thus bioremediation approaches for residual PAM are urgently needed. Biodegradation of PAM and its derivatives has been studied only in the last two decades, with most emphasis on acrylamide biodegradation.

Filamentous, nitrogen-fixing cyanobacteria form extensive summer blooms in the Baltic Sea.

Molasses are poor in nitrogen sources, so starvation stress is present from the beginning. To prevent this scenario, a nitrogen source is usually added. The produced biomass is then dehydrated on a hot air bed. Therefore, thermal stress is relevant in the process, plus the obvious rise in osmolarity due to the efflux of water, and also an internal
