Abstract
Nowadays, the disposal of waste from human use and
environmentally toxic substances has become an important issue.
Therefore, it is important to use agricultural and environmental wastes to
produce many high-value products by microorganisms. Nanocellulose is
one of the high-value products resulting from the transformation of
cellulosic materials, including cellulosic agricultural waste.
Nanocellulose is used in many fields such as biomedical products, wood
adhesives, batteries, catalysts, electroactive polymers, fibers, textiles,
food packaging, antimicrobial films, paper products, cosmetics, cement
and many other uses.
In this study, nanocellulose was produced from cellulosic
agricultural wastes such as rice straw and cotton fibers by some
cellulolytic fungi. Tests were conducted to indicate the formation of
nanocellulose by measuring the endocellulase efficiency, and measuring
the turbidity ratio. Endocellulase efficiency expresses the partial
decomposition of cellulose, while the turbidity indicates the presence of
nanoparticles in the solution. In addition, the optimal conditions for
maximizing nanocellulose production were performed. The produced
nanocellulose was subjected Transmission Electron Microscope (TEM)
and particle size distribution analysis to determine its characteristics.
The obtained results can be summarized as follow
