Description
Deepa Bartak and seven co-authors test how microbes in bentonite clay respond to heat and pressure. Bentonite is planned as a seal around waste cans in deep sites for radioactive waste. Living microbes in the clay could affect how safe those sites stay over long spans of time.
The team kept clay mixes at set pressures and at high heat for four weeks. They then let the samples rest and checked growth and cell types with gene based tests and a microscope. Pressure alone had little effect on growth. Heat had a strong effect, and some samples did not recover well after hot weeks. The results help set safe heat limits for waste sites.
