Open Prebiotic Environments Drive Emergent Phenomena and Complex Behavior

Life, 2019
We have been studying simple prebiotic catalytic replicating networks as prototypes for modeling replication, complexification and Systems Chemistry. While living systems are always open and function far from equilibrium, these prebiotic networks may be ...

Prebiotic chemistry in eutectic solutions at the water-ice matrix

, 2012
A crystalline ice matrix at subzero temperatures can maintain a liquid phase where organic solutes and salts concentrate to form eutectic solutions. This concentration effect converts the confined reactant solutions in the ice matrix, sometimes making ...

Stabilization by Crosslinking of β‐Galactosidase Immobilized by Adsorption for Application in a Continuous Lactose Removal Process

Biotechnology and Applied Biochemistry, EarlyView.
ABSTRACT Adsorption is the simplest method of enzyme immobilization, but it often requires additional treatments to improve stability. These treatments, however, may impact enzymatic activity. This study investigated the effect of crosslinking on the stability of β‐galactosidase immobilized by adsorption on A‐568 resin and its implications for ...
