''Lactobacillus'' species can be isolated on agar plates by using a selective media called Rogosa SL. Rogosa SL agar contains ammonium citrate, sodium acetate, a relatively low pH, and acetic acid, which select for ''Lactobacillus'' while inhibiting mold and other bacteria. This medai medium will not inhibit yeast on it's own, however. If inhibiting yeast is a requirement then add 10 mg/L cycloheximide to inhibit most yeast <ref>[http://basementbrewlab.com/lab/lab-media/sla/ Rogosa SL Agar (Lactobacillus). Basement Brew Lab.
