SEM observation of ramie fibers and depolymerization capacity analysis of PelA, PelC, and PelA+PelC.

Abstract

<p>(A) SEM observation of ramie fibers before (a, b) and after treatment with purified PelA (c, d), PelC (e, f), PelA+pelC (g, h). Scale bars: 10 µm (a, c, e, g) and 1 µm (b, d, f, h). (B) Depolymerization capacity of PelA, PelC, and PelA+PelC for different substrates. Enzyme dosage of 30 mU PGL for each group; PelA+PelC, treatment with a mixture of PelA and PelC at PelA:PelC = 5∶3; Sum of PelA and PelC, calculated sum value of PelA and PelC based on its proportion and depolymerization.</p
