Three different kinds of enzymes (pectinase, cellulase, laccase) were used to treat BF, then biocomposites were fabricated by BF and poly(hydroxybutyrate-co-valerate) (PHBV) through melt blending and injection molding process. The modification effects of BF treated with enzymes were evaluated by ...
Some bacteri a can “eat” other things by changing the chemicals ( 化学物质) in those things into something that will help the bacteri a grow.The secret to this is enzymes (酶). Bacteri a use enzymes to cause chemical changes. Enzymes can work like a pair of scissors, cutting and ...
