Taxonomic note
Results of phylogenetic analysis by Sayama et al. (1995: 419) indicated that B. braunii Kützing Berkeley strain is a member of the Chlorophyta and possibly related to Characium vacuolatum and Dunaliella parva (Chlorophyceae). Senousy et al. (2004) investigated the phylogenetic placement of four isolates of B. braunii (representing A, B and L chemical races). They found that these four isolates form a monophyletic group whose closest relatives are in the Trebouxiophyceae (unrelated to the sequence reported by Sawayama et al. 1995). The closest known relative of the four isolates of B. braunii is the genus Choricystis. Senousy et al. consider polyphyly of B. braunii to be unlikely and suggest that the presence of a contaminant could explain the results. Weiss et al. (2010) isolated the Berkeley strain nuclear SSU (18S) rRNA and ß-actin cDNA and used these sequences for phylogenetic analysis to confirm that the Berkeley strain belongs to the Tebouxiophyceae. - (21 September 2010) - G.M.

Habitat note
Widely distributed in many types of aquatic habitat including ditches, bog pools, open water tanks, ponds and lakes (John & Tsarenko 2002). - (07 July 2010) - G.M. Guiry

Usage note
B. braunii has liquid-hydrocarbon biosynthetic capabilities and is therefore a promising source of renewable hydrocarbon fuels (Weiss et al. 2010). - (20 September 2010) - G.M. Guiry
