Methanogenesis is the conversion of CO2 to methane (CH4) using microbes. In the context of CO2 usage, the process of methanogenesis using native microbes from a particular reservoir can be a very slow process without any external intervention. The study detailed in this complete paper investigates the use of agriculture byproducts such as palm oil mill effluent (POME) as substrates, along with potential microbial isolates that can produce biohydrogen at high temperatures. The authors write that stimulation of microbes using POME as substrate with hydrogen (H2)/CO2 supplementation is important in accelerating the rate and yield of CH4 production.
Introduction
The authors write that a population of microbes isolated from sludge of agriculture wastes, when given proper conditions and nutrients, was able to accelerate the rate of methanogenesis.
