Sterile breeding enclosure - for cultures for inoculating milk or whey

摘要

Breeding enclosure consists of a column, hermetically closed by a lid, with a dipping tube set in the wall and descending nearly to the bottom; its upper end is provided with a tap. An air inlet communicates with the inside of the column through a sterilizing filter. A rubber covered inoculation plug is also provided together with a thermometer and manometer, for indicating the pressure in the column. The culture is obtd. free from infection and it can be transferred, through the dip tube, in an aseptic manner into the milk or whey for complementary prepn. operations. Transfer is effected with sterilized nitrogen under pressure.
