Methanotrophs such as [https://en.wikipedia.org/wiki/Methylococcus_capsulatus Methylococcus capsulatus] can use methane and methanol as both a source of energy as well as a carbon source.

	Traditional hydroponic farming is complex and labor intensive. In contrast, growing and harvesting large grasses such as ''Miscanthus Giganteus'' is simple to do in a large scale and automated way. These grasses can then be broken down via cellulases to provide an accessible source of glucose, along with other industrially useful compounds such as THF (a common solvent)<ref>https://pubs.acs.org/doi/pdfplus/10.1021/acs.chemrev.8b00134</ref>.
