In an innovative gas fermentation process, reducing the concentration of carbon dioxide was found to significantly improve microbial production of the biodegradable plastic poly[(R)-3-hydroxybutyrate]. Researchers found that hydrogen-oxidizing bacteria grown under safe, nonflammable gas conditions enable more efficient production of biodegradable plastic at lower CO2 levels. The study provides a promising strategy for sustainable carbon recycling and efficient CO2 utilization.

But now a new Batman trilogy is finally doing justice to one of Gotham’s most terrifying villains.
