Abstract

  1. 1.

    The cellular content of galactolipids in Chlorobium and Chloroflexus is not related to bacteriochlorophyll content nor to the total amount of chlorosome material in the cells.

     
  2. 2.

    Chlorosomes of both bacteria were agglutinated by Ricinus lectin and the agglutination was increased after treatment of the chlorosomes with trypsin.

     
  3. 3.

    When cell free preparations of both bacteria were treated with trypsin prior to centrifugation on sucrose gradients, the resulting chlorosome fractions were less contaminated with material derived from the cytoplasmic membrane than when trypsin was not employed.
