Self-described "pilot, aerospace engineer, and mad scientist" YouTuber Jack Schneider's video Growing Microbes in Jet Fuel explains that if a layer of water accumulates below jet fuel (due to separation or perhaps other reasons) microbes (bacteria, algae...) can grow in the water and "eat" the fuel:

...since water is denser than jet fuel it sinks to the bottom and creates a layer where microbes can form. Basically the microbes can eat the jet fuel but live in the water and I think that's really interesting. This is a problem in jet fuel tanks because these microbes' byproducts can cause corrosion.

Question: From a microbe's point of view, besides the calorie content of the carbohydrates (hydrocarbons) what are the trace components of jet fuel from which microbes derive nutritional value, and which of their byproducts can (potentially) cause corrosion?

Just for example: life is based on proteins made of amino acids, and two of these (Methionine and Cysteine) have a sulfur atom. The human body for example (though not a microorganism) is 0.3 % sulfur by weight. So a 70 kg body has about 11 kg of protein, and 200 grams of that is sulfur!

This answer to Why is water-contaminated fuel bad, but water-injection is not? mentions

Water not removed from the tank supports microbial growth.

and this answer to Why aren't "fuel polishing" systems removing water & ice from fuel in aircraft, like in cruising yachts? mentions

...you have ideal conditions for the growth of microbial life in the fuel. This life (technically known as "goo") will, if left to grow rampant, clog your filters to the point where the engine eventually shuts down from lack of fuel.

But neither mention nutritional details nor corrosion.
