Biomass yield

Definition

Biomass yield refers to the amount of biological material produced per unit of input, typically measured in grams of biomass per gram of substrate. This concept is crucial in understanding how effectively microorganisms or plants convert raw materials into usable biomass, which is essential for applications in systems biology and metabolic modeling. High biomass yield indicates efficient metabolic pathways and can impact overall productivity in biotechnological processes.
