Maintenance of Cultures
Cultures sent to customers remain alive for at least 14 days provided that the following precautions are observed.
Cultures should be unpacked immediately after receipt and stored at 15-18°C under low light intensity (north window, no direct sun light, or weak white fluorescent light).
Screw caps or vessels should be loosen but not removed. Further maintenance or multiplication of cultures requires transfer into new culture media. This presupposes experience in simple microbial techniques.
