A microcalorimetric method of studying mould activity as a function of water activity
This paper presents a new method of studying mould activity as a function of water activity by measuring the heat produced by the fungal metabolism. During a measurement a small sample (<1 g) of a moulded substrate is moved between a humidity generator, where it is conditioned to a certain water activity, and a microcalorimeter, where the heat production rate is measured. This is repeated for diff
