✦ Synopsis

Heating treatment as a permeabilization method for plant cells was examined on the release of anthocyanin pigments from strawberry cells. The release rate of anthocyanins followed an Arrhenius-type dependency on temperature. The death rate was observed to be peculiarly low at 45 • C, the temperature at which the heat shock protein was induced. Thus, the release of anthocyanin from viable cells depends on the functioning of the heat shock protein probably. The treatment with calcium after heating was observed to restore viability. An elevated rate of the release of anthocyanins, which were likely accumulated in vacuoles, was achieved after they had been gradually released for 45 min.

Elevated temperatures (52, 60 and 65 C) were used to enrich hydrogen producers on cellulose from cow rumen fluid. Methanogens were inhibited with two different heat treatments. Hydrogen production was considerable at 60 C with the highest H 2 yield of 0.44 mol-H 2 mol-hexose À1 (1.93 mol-H 2 mol-hex
