“…Previous studies reported that dehydration is an important factor responsible for cellular damage ( 34 ). This is because water in cells contributes significantly to cell stability and its removal can lead to structural and functional integrity changes in cell membrane ( 34 ). The dehydration processed by heating is prone to thermal stress which also can damage cellular.…”

“…Additionally, cells suffered more damage with the increase of dehydration temperature. Spray drying is a typical method with high temperature ( 34 , 35 ). 55°C used in our study is much lower than those methods with high temperature, and LG-8 cell fragments dried at 55°C have a more prominent ability to bind ZEN and did not differ significantly from fresh cells in solution.…”

The application of LG-8 and its dry fragments as zearalenone (ZEN) adsorbents was investigated. The study showed that Geotrichum candidum LG-8 and its fragments dried at 55°C or through lyophilization are able to adsorb around 80% of ZEN. However, besides in water and 55°C-drying conditions, SEM indicated that higher 90% of ZEN binding tended to occur when cell walls of fragments were intact with less adhesion among themselves. Notably, ZEN/LG-8 fragments complexes were quite stable, as only 1.262% and 1.969% of ZEN were released after successive pH treatments for 4 h and 5 min. The kinetic data signified that adsorption of ZEN onto LG-8 fragments followed well the pseudo-first-order kinetic model. Isotherm calculations showed Langmuir model was favourable and monolayer adsorption of ZEN occurred at functional binding sites on fragments surface. Therefore, we conclude that it can be an alternative biosorbent to treat water contained with ZEN, since LG-8 is low-cost biomass and its fragments have a considerable high biosorption capacity avoiding impacting final product quality and immunodeficient patients.
