A microbial metabolite capable of chelating calcium is designated as_____________________?
Show answer Hide answer
Answer: B. 2-ketoghconic acid
Explanation
2 ketogluconic acid is a powerful organic acid metabolite produced by specific soil dwelling bacteria. This microbial metabolite successfully chelates insoluble calcium and mineral ions to form soluble complexes. Chelation mechanisms allow microorganisms to solubilize essential mineral nutrients from surrounding rock substrates. Microbial metabolites are organic compounds synthesized by microorganisms during growth and fermentation phases. Chelation involves forming multiple chemical bonds between organic molecules and single metal ions. Organic acids lower ambient soil pH while simultaneously binding metallic cations in solution.
Agricultural researchers study calcium solubilizing bacteria to improve soil nutrient availability for crops. Bioremediation techniques utilize microbial metabolic byproducts to mobilize heavy metals in contaminated soils. Understanding organic acid excretion helps explain how weathering contributes to soil mineral development. Pyruive acid is a central metabolic intermediate in cellular respiration rather than a specialized calcium chelator. Carbon dioxide is a gaseous respiratory byproduct rather than an organic acid chelating metabolite. Phospheric acid contains phosphorus, but the correct microbial chelator is specifically 2 ketogluconic acid.
