Going from 16S to carbon utilization

[primordialsoup77]

Say I have a 16S dataset that has been assigned taxonomic labels and I want to associate the resulting taxa with their carbon inputs and outputs. Is there a standard way to do this, or does anyone have a suggestion for what database I could use to achieve this? Thanks.

I should mention that my overall goal would be to build a network that models carbon flux through a system.

There's picrust. However, in my opinion 16S to function is not possible. You can have essentially 100% identical 16S sequences from two genomes that nonetheless have over a thousand unique genes each. Due to stuff like this, 16S to function results are IMO garbage.

That's an interesting tool. Thanks. I think you make a good point. Even applying substantial domain knowledge to the model and supplementing with, for example, biogeochemical data the results would be suggestive at best.
