Gelidium

Gelidium is a higher-grade agar used for creating culture mediums for the promotion of bacteria cultures. Use this product for science projects. This can only be made from species of Gelidium because the resulting agar has a low gelling temperature (34-36°C) that allows the addition of other materials to the agar with a minimum risk of heat damage. Gracilaria and Gelidium produce agars that gel at 41°C or higher. Bacterial agars must not contain anything that might inhibit the growth of bacteria, such as trace metals, soluble carbohydrates or proteins, nor should they contain any bacterial spores. They must not interact with any materials that must be added as nutrients for the bacteria under study. The gels must be strong and have good clarity.
