Based on these methodology limitations, fraction Am-2 was submitted to an alternative strategy, based on mild acid hydrolysis to depolymerize the native SPs for different times, and the in vitro inhibitory effects on TG in 60-fold diluted human plasma were examined using the chromogenic method by a continuous detection system.
Trichoderma reesei is well known as an efficient producer of cellulases [12, 13] and is the main industrial source of cellulases and hemicellulases used to depolymerize biomass to simple sugars that are converted to chemical intermediates and biofuels such as ethanol [14].
Haig says GreenMantra's market differentiation is that it can selectively depolymerize plastics through a highly tunable catalytic process.
Current processes to break apart, or depolymerize, nylon-6 typically must take place at high temperatures and high pressures.
Hydroxyl radicals can depolymerize polysaccharides, cause [ILLEGIBLE TEXT] strand breaks, inactivate enzymes, and initiate lipid peroxidation (6).
those of Betula resinifera) are those that readily depolymerize into reactive products.
The procedure can be explained as follows: 1) oxygen is taken up rapidly by solution containing sodium sulfite with the oxygen going into solution immediately, oxidizing sulfite to sulfate; 2) in the presence of oxygen, metals or reducing agents may initiative sulfite oxidation that, in turn, activates the radical chain reaction in which radicals may polymerize; 3) the radical reactions may be a strong absorbent of molecular oxygen and produce enough energy to polymerize and depolymerize once initiated; 4) in the presence of sulfite, bacteria can rapidly take up glucose and use it in cell synthesis during carbon dioxide production; and 5) bacteria absorb sulfite rapidly and use the energy for metabolism.

11,12) Microbes in composted sewage sludge are able to depolymerize silicones including cyclosiloxanes to dimethylsilanediol: thus, both biotic and abiotic mechanisms for silicone depolymerization have been demonstrated.
Chitosan will gradually depolymerize to release N-acetyl-b-D-glucosamine, which initiates fibroblast proliferation and helps in ordered collagen deposition and stimulates increased level of natural hyaluronic acid synthesis at the wound site.
