What is Tryptone Soya Broth (TSB) used for?

TSB is a general-purpose nutrient medium widely used for cultivating a broad spectrum of microorganisms, including bacteria and fungi. It is particularly valuable for sterility testing, microbial limit testing, and general microbial growth in various industries.

Does this product require refrigeration?

Dehydrated Tryptone Soya Broth typically does not require refrigeration prior to reconstitution. It is usually stored in a cool, dry place, protected from light and moisture, at room temperature.

How is TSB prepared for use?

TSB powder is typically dissolved in purified water according to the manufacturer's instructions, then sterilised, commonly by autoclaving. The specific concentration and sterilisation parameters will be detailed on the product label.

What is the significance of EP/USP/BP/JP compliance?

EP/USP/BP/JP compliance indicates that the product meets the stringent quality and performance standards set by the European, United States, British, and Japanese Pharmacopoeias, respectively. This is crucial for pharmaceutical and medical device applications where regulatory adherence is paramount.

Can this medium be used for anaerobic bacteria?

While TSB is a general-purpose medium, it is primarily aerobic. For culturing strict anaerobes, specific anaerobic conditions or a more specialised medium might be required, though TSB can support facultative anaerobes.

Soybean Casein Digest (SCD), also known as Soybean-Casein Digest Medium or Tryptic Soy Broth (TSB), is a general-purpose nutrient medium used for cultivating a wide range of microorganisms, including bacteria and fungi. It's especially valuable because it's rich in nutrients derived from enzymatic digests of soybean meal and casein (milk protein)
