Toxicity Assessment and Bioremediation of Deep Eutectic Solvents by Haloferax mediterranei: A Step toward Sustainable Circular Chemistry

mycolabadmin

This research demonstrates that a salt-loving microorganism called Haloferax mediterranei can safely tolerate and even metabolize certain eco-friendly solvents known as deep eutectic solvents (DESs). These solvents are promoted as green alternatives to toxic chemicals, but their safety wasn’t well understood. The study found that this hardy microorganism can use some components of these solvents as food sources, suggesting it could help clean up waste containing these chemicals in an environmentally friendly way.

Fusarium spp. in Metalworking Fluid Systems: Companions Forever

mycolabadmin

Researchers analyzed over 48,000 metalworking fluid samples from machines worldwide over 10 years and found that fungal contamination is very common, especially on machine surfaces. While companies add chemicals called fungicides to prevent fungal growth, these chemicals have limited effectiveness and fungi often survive or adapt to them. As regulations increasingly restrict these fungicides, the manufacturing industry will need to find new ways to prevent fungal contamination by changing the chemical composition of metalworking fluids themselves.

A Discretized Overlap Resolution Algorithm (DORA) for resolving spatial overlaps in individual-based models of microbes

mycolabadmin

Scientists developed a new computer algorithm called DORA that helps simulate how microbes grow in crowded environments. The algorithm tracks where individual microbes are located and prevents them from overlapping by using a grid system instead of comparing every microbe to every other microbe. This makes simulations much faster, especially when there are tens of thousands of microbes present, allowing researchers to study biofilm formation and microbial colonies more efficiently.
