This name is of an entity that is currently accepted taxonomically.

Type information
Type locality: In lacu Neoburgense, Helvetiae [Lake Neuenburg, also known as Lake Neuchatel, Switzerland] (Kützing 1849: 892). Type: A. Braun 115; L? Notes: Isotype: UC 790500

Taxonomic notes
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 Sep 2010) - Wendy Guiry

Habitat notes
Widely distributed in many types of aquatic habitat including ditches, bog pools, open water tanks, ponds and lakes (John & Tsarenko 2002). - (7 Jul 2010) - Wendy Guiry

Usage notes
B. braunii has liquid-hydrocarbon biosynthetic capabilities and is therefore a promising source of renewable hydrocarbon fuels (Weiss et al. 2010). - (20 Sep 2010) - Wendy Guiry

General environment
This is a freshwater species.
