For my research we used mason jars that were cleaned thoroughly. After filtering just submerge the biomass in 70-90% ethanol and they can be stored in a fridge for quite some time. If ...

However, growth rate measurements in microbiology are usually done on cell populations consisting several cells. You generally do not observe any oscillation because: Cells are not synchronized ...

I mention this both to make it clear that although, like the poster, I am not an expert in the topic one can get considerable mileage through ...

Think of every human being as being a walking petri-dish, full of growth medium. When you grow a large colony of micro-organisms, you are allowing that population to experience a larger number of mutations. Every mutation is one more potentional strain that can beat the defenses of our immune systems, even those provided by vaccines. So, if you don't get ...
