The metabolic conversion of sugar is driven by a complex series of enzymatic reactions. Enzymes are proteins, and all proteins are built from amino acids, which contain nitrogen. Without sufficient nitrogen, a microorganism cannot produce the necessary enzymes to effectively break down and ferment sugars.
A lack of nitrogen is a common cause of slowed or incomplete fermentation because the microbial population cannot grow to the size needed to process all the available sugar.
High sugar content will make oxygen much harder to access in a medium.
Soon as oxygen gets scarse, nitrogen won't convert, aerobic becomes anerobic then it's just a matter of time...
Nitrogen and sulfur are two nutrients that can cause lime green but the thing is it comes from either new or old growth depending on its mobility. When you have a plant that's lime green all over with no obvious starting points its often a sign that the pH has gone alkaline (not always) reason for which varies.
Compromised iron uptake can cause a plant to turn pale green or lime green, a condition called chlorosis, because iron is essential for chlorophyll synthesis. When a plant cannot take up enough iron, it can't produce enough chlorophyll, and this deficiency leads to the yellowing of leaves all over with no obvious starting point.
Mediums that are oversaturated with water and lack oxygen, iron uptake is crippled because the iron becomes too soluble or is in a toxic form. Under anaerobic conditions, ferric iron ((Fe^{3+})) is reduced to ferrous iron ((Fe^{2+})). While (Fe^{2+}) is more soluble and readily available, the excessive concentration in oversaturated, low-oxygen environments can become toxic to many organisms and interfere with uptake mechanisms.
When left unprocessed by microorganisms, sugars in a medium can cause several problems, depending on the concentration, moisture level, and surrounding conditions. The issue is not the presence of sugar itself, but what happens when it is combined with other elements in an unsterile environment.
