Abstract Cellulose nanofibers, a sustainable and promising material with widespread applications, exhibit appreciable strength excellent mechanical physicochemical properties. The preparation of cellulosic nanofibers from food or agricultural residue is not sustainable. Therefore, this study was designed to use three halophytic plants ( Cressa cretica, Phragmites karka , Suaeda fruticosa ) extract cellulose for the subsequent conversion composites. other extracted biomass components including lignin, hemicellulose, pectin were also utilized obtain industrially valuable enzymes. maximum pectinase (31.56 IU mL −1 ), xylanase (35.21 laccase (15.89 produced after fermentation pectin, lignin S. P. C. cretica respectively. methylated (with degree substitution 2.4) subsequently converted into composite using polyvinyl alcohol. Scanning electron microscopy Fourier‐transform infrared spectroscopy confirmed successful synthesis composites made up had high tensile (21.5 15.2 MPa) low biodegradability (47.58% 44.56%, respectively) dumping 3 months in soil, as compared (98.79% 4.9 MPa strength). Moreover, all exhibited antibacterial activity against gram‐negative bacteria Escherichia coli Klebsiella pneumoniae gram‐positive Staphylococcus aureus ). Hence, emphasizes possibility various industrial applications plants.
