Changes

Two Lacto strains from White Labs (delbrueckii and brevis) and Wyeast (buchneri and brevis), and the Omega L. plantarum strain were tested. All were grown on AOAC plates (a ''Lactobacillus'' medium) supplemented with cycloheximide. All Lacto cultures were cultivated in liquid AOAC at ~90°F (no stirring) to maximum cell density (achieved in about 3 days). 200 ml of each ''LactobacilusLactobacillus'' was pitched into 2 liters of autoclave-sterilized unhopped wort with a starting gravity of 1.037. Each fermentation was incubated for 2 weeks at ~90°F, periodically checking gravity and pH.
