oatmeal_agar_isp_3

CultureMech:009815 bacterial COMPLEX SOLID_AGAR
Original name: Oatmeal Agar (ISP-3)

Overview

External ontology
TOGO:M42 — Oatmeal Agar (ISP-3)
Applications
  • Microbial cultivation
pH
7.2
Notes
TOGO M42 mirrors JCM Medium 50: oatmeal is cooked or steamed in distilled water, filtered through cheesecloth, restored to 1 L, supplemented with 1 mL Trace salts solution and agar, adjusted to pH 7.2, and autoclaved. The Trace salts solution stock is modeled as a solution rather than as undiluted final-liter ingredients.
