May I feed the animals on a regular basis during the first three weeks?

No, you need to feed them very sparingly with maximum 25% of the usual amount. The bacteria are adapting to the current water load and may not be overstrained. A slow increase allows the bacteria a stable adaptation to their environment.

How are the filter bacteria (nitrobacter) preserved in the bottles? How can the bacteria survive inside?

The bacteria in the products are contained in a nutrient solution which meets the "minimum requirements", as full-scale metabolism would shorten the shelf life. As long as the bottles are in their original packaging and stored at temperatures between 4-35 °C the shelf life is 18 months.

If the liquid is clear or has occasional small brownish flocks, the product is fine. The smell should be barely discernible. If the liquid smells of rotten eggs or if it contains black flakes, the product is no longer suitable for use.

Do the "filter bacteria" pose a risk to sensitive persons, as they could potentially be transmitted by air?

No, these bacteria are generally harmless to humans.
They can not get into the air, as nitrifying bacteria are generally substrate bound and bound to a medium that is aqueous to at least moist.
