We just kept adding more calories, from new varieties of junk food exploiting the current nutrient fixation.
For decades, we have shifted from one nutrient fixation to the next- fat, carbohydrate, sugar, gluten -- and generally been left behind by the big picture.
Root-associated bacteria can promote plant growth by direct and indirect mechanisms, the former including nutrient fixation and solubilisation and phytohormones synthesis.
The judgment of our proclivity for mono-nutrient fixations has been rendered, and it is quite harsh; we have been harming ourselves with its unintended consequences for decades.
So it is that when cutting fat let us down, mostly because we approached the enterprise as a pack of gullible nincompoops, we didn't thoughtfully reconsider the proposition of mono-nutrient fixations.
Plant growth-promoting bacteria can stimulate plant growth by replacing soil nutrients through biological N2 fixation, making nutrients more available (solubilization of phosphates) or increasing plant access to nutrients (increasing root surface area or modulating ion transporters) [4].
Effects of temperature include cellular chemical composition, rate of photosynthesis, nutrient uptake, CO2 fixation, and respiration intensity (Tan et al. 2009).
Nutrient accumulation and fixation in microbial biomass occurs most likely through nutrient import by fungi, which may occur through 1) contact with soil, 2) mobilization through interstitial mycelium, the translocation through mycelium growing from wood through soil, and 3) N fixation by bacteria associated with wood-decaying fungi (Rayner and Boddy 1988; Hoppe et al. 2014).
In return, the microorganisms contribute to plant growth and health by nutrient solubilisation, N2 fixation, the production of plant hormones and the degradation of phytotoxic compounds [9], [10].
They are directly involved in the transformation of nutrients, photosynthesis, nitrogen fixation, methanogenesis, phosphate solubility, sulfate reduction and production of other substances, including antibiotics and enzymes and are reservoirs of products of biotechnological interest as, for example, bacteria that produce bioemulsifiers [7].
The inputs of nutrients via atmospheric precipitation and nitrification and fixation of nutrients by microalgae were not considered for this study.
