Food-grade agar can be used as a low-cost substitute for bacteriological agar in the preparation of solid microbial media. No difference was observed in the colony morphology, growth rate, or viability of bacteria grown on solid media prepared using food-grade agar as compared with using bacteriological-grade agar. This simple tip can reduce the cost of the most common solid media by 80% or more.
食品级琼脂可用作制备固体微生物培养基时替代细菌学琼脂的低成本替代品。与使用细菌学级琼脂相比，使用食品级琼脂制备的固体培养基上细菌的菌落形态、生长速度或活力没有差异。这个简单的技巧可以使最常见的固体培养基的成本降低 80% 以上。
