In the current study, cellulose was extracted from sugarcane bagasse and further converted into carboxy methyl cellulose. The morphological, chemical, and structural characterization of synthesizeed carboxy methyl cellulose was performed. Further, the biopolymer was fabricated with mycogenic selenium nanoparticles and used to develop the biopolymer films. The developed biopolymer films were examined for the fruit shelf life stability, antifungal activity, and biodegradation potential. The results revealed that grapes wrapped with biofilms showed enhanced shelf life of fruit at all storage time intervals. The study also witnesses the antifungal activity of biopolymer films with a remarkable inhibitory action on the spores of Fusarium oxysporum and Sclerospora graminicola phytopathogens. Lastly, the biopolymer films were significantly degradable in the soil within two weeks of incubation. Thus, the developed biopolymer films exhibit multifaceted properties that can be used as an alternative to synthetic plastics for fruit packaging and also helps in protecting against fungal contaminants during storage with naturally degradable potential.
在本研究中，从甘蔗渣中提取纤维素，并进一步将其转化为羧甲基纤维素。对合成的羧甲基纤维素进行了形态、化学和结构表征。进一步，用真菌硒纳米粒子制备了生物聚合物，并用于开发生物聚合物薄膜。研究了所开发的生物聚合物薄膜对水果货架期稳定性、抗真菌活性和生物降解潜力的影响。结果表明，用生物膜包裹的葡萄在所有储存时间间隔内都表现出了增强的水果货架期。该研究还见证了生物聚合物薄膜的抗真菌活性，对尖孢镰刀菌和禾谷丝核菌植物病原菌的孢子有显著的抑制作用。最后，生物聚合物薄膜在两周的孵育期内可在土壤中显著降解。因此，所开发的生物聚合物薄膜具有多方面的特性，可以替代合成塑料用于水果包装，并且还具有在储存过程中防止真菌污染物的天然可降解潜力。
