Polysaccharide breakdown products drive degradation-dispersal cycles of foraging bacteria through changes in metabolism and motility

eLife
Most of Earth’s biomass is composed of polysaccharides. During biomass decomposition, polysaccharides are degraded by heterotrophic bacteria as a nutrient and energy source and are thereby partly remineralized into CO2.

Alginic Acid Degradation by Eliminases from Abalone Hepatopancreas

Journal of Biological Chemistry, 1967
Abstract Two separate alginic acid eliminases have been purified from abalone hepatopancreas. Alginase I appeared to be specific for β-1,4 bonds involving d-mannuronic acid units and apperently acts at random on internal bonds. Alginase II appeared to cleave 1,4 bonds involving l-guluronic acid and to work at or near chain ends.

Rational Tuning of Hygroscopic Oscillation of Stacked Nanoflake Assemblies for Continuous Ambient Energy Harvesting

Advanced Materials, EarlyView.
Stacked nanoflake assembly (SNA) membranes can oscillate autonomously, offering opportunities for soft actuation and energy harvesting. This work uncovers the physical mechanism behind the sustained oscillation of SNA membranes in gradient humidity and identifies three governing dimensionless parameters, enabling rational design for optimizing SNA ...
