Nitrile gloves have become a significant environmental pollutant after the COVID-19 pandemic due to their single-use design. This study examines the capability of to use nitrile gloves as its sole carbon energy source. Biodegradation was determined by adapting to increasing nitrile glove concentrations at 1%, 3%, and 5% (/). The growth kinetics of were evaluated, as well as the polymer weight loss. Topographic changes on the glove surfaces were examined using SEM, and FT-IR was used to evaluate the biodegradation products of the nitrile gloves. Following the establishment of a biofilm on the glove surface, the nitrile toxicity was minimized via biodegradation. The result of the average weight loss of nitrile gloves was 2.25%. FT-IR analysis revealed the presence of aldehydes and aliphatic amines associated with biodegradation. SEM showed immersed in the EPS matrix, causing the formation of cracks, scales, protrusions, and the presence of semi-spherical particles. We conclude that has the capability to use nitrile gloves as its sole carbon source, even up to 5%, through biofilm formation, demonstrating the potential of for the degradation of nitrile gloves.
在新冠疫情之后，由于腈手套的一次性使用设计，它们已成为一种重要的环境污染物。本研究考察了[具体微生物名称未给出]利用腈手套作为其唯一碳能源的能力。通过使[具体微生物名称未给出]适应1%、3%和5%（重量/体积）不断增加的腈手套浓度来测定生物降解情况。评估了[具体微生物名称未给出]的生长动力学以及聚合物重量损失。使用扫描电子显微镜（SEM）检查手套表面的形貌变化，并使用傅里叶变换红外光谱（FT - IR）评估腈手套的生物降解产物。在手套表面形成生物膜后，通过生物降解使腈毒性降至最低。腈手套的平均重量损失结果为2.25%。傅里叶变换红外光谱分析揭示了与生物降解相关的醛类和脂肪族胺的存在。扫描电子显微镜显示[具体微生物名称未给出]沉浸在胞外聚合物基质中，导致形成裂缝、鳞片、凸起以及存在半球形颗粒。我们得出结论，[具体微生物名称未给出]有能力通过形成生物膜将腈手套作为其唯一碳源，甚至高达5%，这表明[具体微生物名称未给出]在降解腈手套方面具有潜力。
