What is Microbial Carbon Cycle? The Earth boasts a staggering annual production of over 5 × 10^9 tons of plant residues, primarily composed of polymers like cellulose, hemicellulose, polysaccharides, and lignin. The decomposition of these organic remnants constitutes a vital cog in the organic carbon balance, particularly in Soil Organic Carbon (SOC), within terrestrial ecosystems. SOC...
