Polypeptone provide carbon and nitrogen sources, vitamins and growth factors; Neisseria starch can promote the growth characteristics and enhanced hemolytic streptococci; sodium chloride to maintain osmotic balance; agar as culture medium coagulant.
Formulation (per liter):
Peptone: 10g
Beef extract powder :10g
Sodium chloride: 5g
Agar :15g

2.After the medium is cooled to about 50 ℃, sterile procedures, basal medium was added per 100mL defibrinated sheep or rabbit blood 5-10mL, shake pour plate; also dispensing sterile tubes set into the slope. Spare.
3. take the bacteria to be tested fresh pure cultures inoculated crossed or coated on the plate, set the temperature of the incubator training requirements were cultured for a predetermined time.
4. Observe the results.
Quality control:
The following were inoculated after 36 ± 1 ℃ for 24h , the results are as follows:
bacteria name bacteria No. growth status colony characteristics
Escherichia coli ATCC25922 not good hemolysis
Staphylococcus aureus, ATCC6538 good β-hemolytic
Beta-hemolytic streptococcus CMCC (B) 32210 good β-hemolytic
Streptococcus pneumoniae CMCC (B) 31001 good α-hemolytic
