Agar-agar can be obtained from seaweed, such as Gelidium Amansii, G. Subcostatum, G. japonicum, Acanthopeltis japonica and Pterocladia tenuis by extracting with hot water at a temperature of about 80℃ for a long time, neaerly 15 hr. For the purpose of increasing the yield of agar-agar and in order to improve the efficiency of extraction, a dilute solution of sulfuric or acetic acid was employed at a concentration of 0.015 or 0.03 per cent, respectively. It should be notted, however, that agar-agar tends to decompose by acid treatment or by heating for such a long time.With the view of promoting the production of agar-agar by the use of cellulase, the influences of cellulase treatment at various cellulase concentration was investigated using the extract of Trichoderma viride Koji or the cellulase preparation derived from this Koji. A representative result obtained was that the yield of agar-agar became three-fold as large as that of control by incubating Gelidium japonicum with a solution containing 1% cellulase preparation for 4 hr at 40℃.
