Gelidium species of red algae are preferred for bacteriological and pharmaceutical grade agar due to their naturally strong gelling quality. Use a drying oven at 65°C. In the Orient, large quantities of "natural agar" are sold by very small producers and consumed in the form of threads ("strip") or bars ("square") that are usually produced from Gelidium and do not have to meet the above-mentioned specifications.
