B.T.B Lactose Agar – 500 gram Packs

BTB Lactose Agar (Bromothymol Blue Lactose Agar) is a differential culture medium utilized in higher education microbiology curricula to illustrate fundamental concepts in bacterial identification, carbohydrate fermentation, and metabolic differentiation. In academic teaching laboratories, it serves as an essential instructional model for distinguishing lactose-fermenting organisms from non-fermenters based on color changes driven by the bromothymol blue indicator. Students in university microbiology and biology courses employ this culture medium during structured practical coursework to streak cultures, observe colony characteristics, and analyze acid production pathways. Its clear color transitions and reliable nutrient performance yield distinct, reproducible experimental results that connect theoretical microbial metabolism with direct visual observations. Formulated specifically for general educational laboratory use, this 500g package provides a generous, reliable supply for routine student practicals, faculty demonstrations, and hands-on microbiology laboratory exercises. Store BTB Lactose Agar in a cool, dry, well-ventilated area in a tightly sealed container protected from direct light, strictly adhering to standard educational laboratory biosafety practices.
