Mix ingredients
except NaHCO3
L-Cysteine·HCl·H2O and Na2S·9H2O
and bring to a boil for 5-10 sec. Cool down under a stream of H2-CO2 (80:20)
and add NaHCO3 to the medium. Dispense the medium into suitable culture vessels (e.g.
20 ml of the medium in 120 ml serum bottles) under a stream of H2-CO2 (80:20) and seal with butyl rubber stoppers. Separately autoclave cysteine·HCl and Na2S·9H2O as 5% solutions
respectively
under a N2 atmosphere. Prior to inoculation
aseptically and anaerobically add the cysteine·HCl and Na2S·9H2O solutions. Pressurize the inoculated vessels to 200 kPa H2-CO2 (80:20).
