The cellulose contents of Indian seaweeds

Abstract

Cellulose content as well as alpha (α) and beta (β) celluloses were evaluated in 21 seaweed species belonging to different classes growing in Indian waters. The greatest yields of cellulose (crude) and β-cellulose were obtained from Caulerpa taxifolia (approx. 11.0% and 5.2%, respectively), whilst α-cellulose (approx. 8.2%) was the greatest in Padina tetrastromatica. The lowest cellulose (crude), α-and β-contents were recorded from the calcareous red alga Liagora ceranoides (approx. 0.85%, 0.62% and 0.18%, respectively). There was no variation in the yields of cellulose in the brown algae, whilst wide variations in the yields were found in the green and red algae.

Comparison of different process strategies for bioethanol production from Eucheuma cottonii: An economic study

“…S3 (c), the characteristic bands of MCR were found to be similar to earlier reported FTIR spectra of cellulose in the literature (Siddhanta et al, 2011). A strong band at 1437 cm À1 defined the cellulose allomorph as cellulose I (Dayal et al, 2013).…”

Cellulose from the green macroalgae Ulva lactuca: isolation, characterization, optotracing, and production of cellulose nanofibrils

“…Aside from lignocellulosic biomass, cellulose is found in the cell walls of marine biomass such as macroalgae (Siddhanta et al 2009(Siddhanta et al , 2011(Siddhanta et al , 2013Koyama et al 1997;Chen et al 2016;Mihranyan 2011). Cellulose from macroalgae has gained increased attention recently since it offers several benefits compared with cellulose from land-based biomass.…”

“…Cellulose has been successfully extracted from both red, green and brown macroalgae (Siddhanta et al 2009(Siddhanta et al , 2011(Siddhanta et al , 2013Koyama et al 1997;Chen et al 2016;Mihranyan 2011). The gross content of cellulose varies significantly between different species, ranging from 1 to 15% (w/w) (Siddhanta et al 2009(Siddhanta et al , 2011(Siddhanta et al , 2013Koyama et al 1997). The cellulose content shows seasonal variations and is strongly dependent on the maturity of the biomass (Schiener et al 2015;Starko et al 2018).…”

Aktivitas Antioksidan Padina sp. pada Berbagai Suhu dan Lama Pengeringan

“…Padina sp. merupakan salah satu spesies rumput laut cokelat yang dilaporkan memiliki aktivitas antioksidan (Armah et al, 1999;Amornlerdpison et al, 2007, Zubia et al, 2007Matanjun et al, 2008;Kumar et al, 2010;Siddhanta et al, 2010). Chew et al (2008) melaporkan bahwa Padina antillarum memiliki aktivitas antioksidan paling tinggi dibandingkan dengan Caulerpa racemosa dan Kappaphycus alvarezzi.…”
