Exploiting the synergistic interactions between plants and microbes by harnessing soil microbes to supply crops with nutrients may be a further strategy.
As little as one-hundredth of 1percentt of the coal in the United States converted into methane by microbes would supply the country's current annual natural-gas demands, says Andrew Scott, a former professor of economic geology at the University of Texas at Austin.
There are also more traditional photosynthetic MFC configurations where photosynthetic organisms live with other microbes and supply products to heterotrophs [67].
In the rumen, methanogens depend on fermentative microbes to supply H2, usually at very low concentrations, and M1 appears to have adapted its lifestyle for growth at low levels of H2 using the mcrI system only.
Areas under investigation include the selection of electrode materials for optimal electrochemical performance and maximising electrode surface to volume ratios; improving charge transfer between microbes and electrodes either chemically or by mechanical design; and finding and maintaining optimal living conditions for microbe colonies, efficient supply of nutrients and removal of effluent.
Roots of aquatic plants provide extended surface for benthic microbial community to rest and act as a customized niche for each microbe ensuring the continuous supply of nutrients, organic carbon and oxygen (Stottmeister et al. 2003).
In both rhizobial and mycorrhizal symbioses, the plant rewards its microbe partners with a supply of carbon and energy.
Plant growth in organic systems greatly depends on the functions performed by soil microbes, particularly in nutrient supply.
At this state, physical influences were apparently overlapped by biological effects due to higher energy supply to microbes, which could be offered by spatial distribution changes of microorganisms and organic substrates within a given soil structure.
The veins may supply the microbes with vital nutrients.
