Is the lichen still alive
I spoke with my mom recently about my Lichen. I am not sure it is till alive. Here is her recipe for checking whether any organism still perspires (that is, releases co2).
- A pH Indicator
- a drop of alkalide (or a very strong base)
- A bit of lichen (or a small bit of the organism you are testing)
Put your lichen or organism fragment in a jar, add in a little alkalide. Just a drop, no more! You don’t want to kill the organism. Insert the pH indicator (strip, or any other cheap indicator)
Put the mixture in a dark place and wait a day or so.
In the morning: See if indicator will change colour
CO2 is acidic, and will eventually neutralise the alkalide.
Can be used on any perspiring organism
