Ok folks,
I've just spent the majority of the night researching documentation to support evidence that molasses can be taken into a plants nutrient stream via the roots.
Of all the documents I've reviewed, (about 50), the two quotes below sum up the information.
If Molasses undergoes bioconversion to gain fructose diphosphate, then I agree that it becomes available to the plants to uptake into the plant via the root mass. A much smaller amount of fructose diphosphate may be available to the plant via raw molasses, but the available amount is negligible.
Thus, putting raw molasses into a soil media can increase advantageous soil microbes, but putting it into any other delivery form such as water for hydroponic solutions is pointless.
As a soil additive, molasses is a good thing to do. However, beware of anyone telling you that molasses in raw form can be utilized by plants via the roots. This simply isn't true.
Stoney.

Sugar beet molasses was used as carbon source forSaccharomyces cerevisiae growth and as substrate for bioconversion to fructose diphosphate.
The highest level of fructose diphosphate (26.6 g/L) was reached after 10 h incubation of permeabilized cells under appropiate molasses and phosphate to cell ratio and represented a 64% yield of bioconversion.

Role of Alkaline Fructose-1,6-Diphosphatase in Plants

THE splitting of fructose-1,6-diphosphate to fructose-6-phosphate is an important step in the pentose phosphate reductive pathway of carbohydrate metabolism and in photosynthesis.
An absolutely specific, alkaline and magnesium-ion-requiring fructose diphosphatase in spinach leaves has been reported. The leaves contained another fructose diphosphatase with a neutral pH optimum, with no requirement for magnesium ion and capable of splitting also sedoheptulose-diphosphate.
The presence of a third fructose diphosphatase, with an optimum at acid pH and with activity towards ribulose-diphosphate also, was reported in spinach leaves.
Racker and Schroeder believed that the alkaline fructose diphosphatase did not participate in photosynthesis, being absent from plastids isolated from homogenates prepared in aqueous media.
Smillie, however, obtained evidence to show that alkaline fructose diphosphatase was actively involved in photosynthesis. The enzyme was present in all photosynthetic tissue examined, and, using non-aqueous media for cell disruption, it was possible to show that the activity was localized in the plastids.
An investigation by us of the diurnal activity of fructose diphosphatases in the leaves of the tapioca plant (Manihot utillissima) has provided additional evidence, indirectly, for the involvement of the alkaline enzyme in photosynthesis. Homogenates of the leaves showed three distinct pH optima (-acid, neutral and alkaline-) for phosphatase activity towards fructose-diphosphate. Of these only the alkaline enzyme showed marked diurnal variation in activity, being about three times as active in the daytime as at night.
