Fig. 4From: Insights into the action of phylogenetically diverse microbial expansins on the structure of cellulose microfibrilsScanning electron microscopy images of hardwood pulp. Hardwood pulp SEM images after treatment with XsaEXLX1, DaqEXLX1, CmiEXLX2, NspEXLX1, and PcaEXLX1 shown at 10 and 2 µM resolution using 500 × and 2500 × magnification, respectively. The reference (without protein) and BSA-treated control samples are shown on the bottom. The major impact of microbial expansin treatments are highlighted in the 2 µm resolution images using phosphoric green framesBack to article page
