Lactose Gelatin Medium (Base) 500g (UN NR) Each

Composition

The final medium is formulated to a pH of $7.5\pm 0.2$ (25∘C) and contains:

• Meat peptone (peptic): $15\text{ g/L}$

• Yeast extract: $10\text{ g/L}$

• Lactose: $10\text{ g/L}$

• Disodium hydrogen phosphate: $5\text{ g/L}$

• Phenol red: $0.05\text{ g/L}$

Techniques and Applications

It is suitable for various microbiological techniques, including:

• Microbiological culture

• Microbe identification (specific enzyme detection)

The medium is employed across diverse fields:

• Agriculture

• Bioburden testing

• Environmental

• Food and beverages

• General microbiology

Suitability

It is a nonselective and differential medium that supports the growth and differentiation of several bacterial genera, including:

• Bacillus spp.

• Proteus spp.

• Serratia spp.

• Staphylococcus spp.

• It is slightly reworded to suggest it is nonselective and differential for Clostridium spp., which is likely the intended organism group.
