title: Flocculation of cell debris from ultrasonicated Escherichia coli.
abstract: Cell debris of Escherichia coli produced by ultrasonication was flocculated with acid. The debris settled at pH 3 and 4, but not at pH 2. Extensive protein precipitate formed in lysates at low pH. The results were compared with whole cells flocculated by acid.
