Microspheres form isothermally from lysine-rich proteinoid when the ionic strength of the solution is increased with NaCl or other salts. Studies with different monovalent anions and with polymers of different amino acid composition indicate that charge neutralization and hydrophobic bonding contribute to microsphere formation. The particles also form in sea water, especially if heated or made slightly alkaline. The microspheres differ from those made from acidic proteinoid but resemble coacervate droplets in some ways (isothermal formation, limited stability, stabilization by quinone, uptake of dyes). Because the constituent lysine-rich proteinoid is of simulated prebiotic origin, the study is interpreted to add emphasis to and suggest an evolutionary continuity for coacervation phenomena.
当用氯化钠或其他盐类增加溶液的离子强度时，富含赖氨酸的类蛋白会等温形成微球体。对不同单价阴离子以及不同氨基酸组成的聚合物的研究表明，电荷中和与疏水键合有助于微球体的形成。微球体在海水中也能形成，特别是在加热或略呈碱性的情况下。这些微球体与由酸性类蛋白制成的微球体不同，但在某些方面类似于凝聚液滴（等温形成、稳定性有限、由醌稳定、染料摄取）。由于组成成分富含赖氨酸的类蛋白具有模拟的益生元起源，该研究被解释为强调并暗示了凝聚现象的进化连续性。
