Fig. 3. Changes in the total EPS/Chl a ratio and bend interval of trichomes before and after the removal of polysaccharide from the BG11-cultured N. flagelliforme suspension. Changes in the total EPS/Chl a ratio and bend interval of trichomes before and after the removal of polysaccharide from the BG11-cultured N. flagelliforme suspension. Data are mean±s.d. (n=4, for EPS/Chl a ratio; n=40, for bend interval). Lijuan Cui et al. Biology Open 2017;6:1329-1335 © 2017. Published by The Company of Biologists Ltd
