Fig. 2From: Microbial synthesis of antimony sulfide nanoparticles and their characterizationThe left tube (tube A) shows a container containing selenium-enriched Serratia marcescens cells which were disrupted by liquid nitrogen and extracted with n-octyl alcohol. Also, tubes B and C show this extracted material before (tube B) and after (tube C) additional extraction with mixed solvents of chloroform, ethyl alcohol and distilled water (3:1:4)Back to article page
