If this is the case, I find it difficult to explain the quick response
(increased brood rearing) when natural pollen collection starts in the
spring. It is my understanding that fermenting pollen into bee bread takes
multiple days.
It is certainly possible that yeast action permits or improves pollen
digestion. It is also possible that some such yeasts operate in the bee gut
and can do their work in a few hours.

Nothing quite like fresh comb to improve brood health.
