Meat Peptones
Meat peptones are proteins from animal sources which have been hydrolysed to provide nitrogen for microorganisms.
They can be tailored to the specific nutritive needs of microorganisms by controlling the quality and origin of the protein,
the quality and source of the enzyme used in the digest, and also the methods used for hydrolysis.

Casein Peptones
PRODUCT GROUP DF
Casein peptones are made from an insoluble precipitate from acidified milk. Hydrolysed caseins are made either by acid
hydrolysis or enzymatic hydrolysis depending on the required molecular weights.

Alternative Protein Source Peptones
The need for non-animal derived products has increased due to concerns about BSE/TSE and their link to animal derived
products. In response BD have developed a broad offering of Soy Peptones, Yeast Extracts and Animal Free Media.
SOY PEPTONES
Soy Peptones are manufactured in the more
traditional manner. The BD Difco Soy
Peptones are all enzymatic digests of soy
flour, which is rich in high quality protein,
carbohydrates, calcium and B vitamins. The
enzymes used in the digestion are from
animal free sources.
YEAST EXTRACTS
Yeast Extract is a water soluble, peptone-like
derivative of yeast cells. BD Yeast Extract is
an autolysate of baker’s yeast, and is used
as an inexpensive source of vitamins,
carbohydrates and micronutrients.
SELECT APS MEDIA
The Select APS media line is manufactured
from non-animal origin ingredients. These
APS media are nutrient-rich formulations
designed to outperform classical meat based
formulations.
Select APS Super Broth is a molecular
genetic medium which will grow E.coli to a
high cell density. There is no glucose thus
preventing acetate build-up in the
fermentation of the organism.
Select APS LB Broth is an excellent all
purpose growth medium for the propagation
and maintenance of E.coli in molecular
biology procedures.
