Sulfur deficiency in soils has become an increasing concern over the past decades. Despite elemental sulfur (S₈) vast utilization as a commercial fertilizer, S₈ has to be biologically oxidized for plant assimilation, drastically limiting its efficiency. Therefore, we propose a new fertilizer in which S₈ structure is more accessible to oxidizing microorganisms by chemical modification via inverse vulcanization technique, a solvent-free copolymerization method, with soybean oil as comonomer. Sulfur oxidation experiments were performed by A. niger submerged cultivation, confirming that the homogeneous rubbery-like material provides enhanced oxidation, with great potential as multifunctional sulfur-fertilizer.

在过去的几十年中，土壤中的硫缺乏已引起越来越多的关注。尽管元素硫（S ₈）广泛用作商业肥料，但S ₈必须被生物氧化以吸收植物，从而极大地限制了其效率。因此，我们提出了一种新肥料，其中以大豆油为共聚单体的逆硫化技术，无溶剂共聚法通过化学修饰使S ₈结构更易于被氧化微生物氧化。通过黑曲霉（A.niger）的深层培养进行了硫的氧化实验，证实了均匀的橡胶状材料提供了增强的氧化作用，具有作为多功能硫肥料的巨大潜力。
