Spectroscopic and Physicochemical Characterization of Sulfonated Cladophora Cellulose Beads
Langmuir, 2018The work presents a full physicochemical characterization of sulfonated cellulose beads prepared from Cladophora nanocellulose intended for use in biological systems. 2,3-Dialdehyde cellulose (DAC) beads were sulfonated, and transformation of up to 50% of the aldehyde groups was achieved, resulting in highly charged and porous materials compared to the

Cellulose nanocrystals (CNCs) are promising materials that are readily extracted from plants and other cellulose-containing organisms. In this study, CNCs were isolated from freshwater green algae (Cladophora rupestris) thriving in a volcanic lake, using hydrobromic acid (HBr) hydrolysis. Morphological and structural studies revealed highly crystalline

Cellulose extraction from Cladophora rupestris for extraction of nanomaterials
IOP Conference Series: Materials Science and EngineeringAbstract Cellulose from macroalgae is potential for the extraction of nanomaterials due to its availability and its great fraction in the biomass. Cladophora rupestris is a macroalgae and is a good material to which a cellulose may be extracted. The said macroalgae has no value-added products or uses yet. It has a lignocellulosic profile

This chapter describes a novel top-down type extraction method of nano-cellulose using enzymatic hydrolysis of microcrystalline cellulose fibers comprising two crystalline allomorphs of cellulose, Iα and Iβ. In this method, the key issue was the selective removal of cellulose Iα phases by preferential hydrolysis of Trichoderma cellulase [1].

Cellulose nanocrystals from marine algae Cladophora glomerata by using microwave-assisted extraction
International Journal of Biological MacromoleculesAlgae of the order Cladophorales are the source of a unique nanocellulose with high crystallinity and a large aspect ratio, enabling broad surface modification. Cellulose nanocrystals (CNCs) are obtained via acid hydrolysis of nanocellulose, which is highly crystalline.
