Guar gum, a plant colloid, costs less than agar and is better suited for growing thermophilic bacteria, but is also more difficult to handle, being more viscous and less transparent. The bacterial polysaccharide xanthan is cheaper as well but forms weaker jellies that, as with carrageenan, might result in puncturing its surface. Other colloids, like alginate (from brown seaweed) and gellan gum (from a bacterium), don’t set solely based on temperature and require additives for gelation. These additives might interfere with microbial growth and make the preparation of those jellies less handy than agar plates.
But have no fear; some aspects of the company are doing quite well. Take, for example, nepotism. The future is looking bright indeed for a rising company star who is now co-CEO of Vantage Studios. That title belongs to Charlie Guillemot, the son of Ubisoft CEO Yves Guillemot.
