Angående hva diastaticus er: The strain description of
Saccharomyces cerevisiae var. diastaticus gives the following information: This yeast is facultative anaerobic, can ferment typical sugars similar to
Saccharomyces cerevisiae plus starches and dextrins. Its morphology is comparable to the bottom fermenting brewer’s yeast
Saccharomyces pastorianus, cells are oval to egg-shaped, mostly single or in pairs.
S. diastaticus suspended in water can survive 10 min at 59.5°C, but all cells die when exposed to 60.5°C for 10 min. This is about 8°C higher than culture yeast or many other wild yeasts can survive at similar conditions. (

Det virker som om det er mer enn bare evnen til å bryte ned stivelse og dekstriner som skiller diastaticus fra vanlige cerevisiae-typer.
Jeg er litt usikker på hva du mener med det første der. Men det er ikke noe problem å påvise diastaticus, i hvert fall:
