Abstract The paper is a review on the extraction processes of cellulosic fibers from flax and hemp. two lignocellulosic crops have long history use by humans for bast among other purposes. utility declined over time with industrial advances changes to economy, but late, an increase focus environmental impact sustainability, there renewed interest in these resources. biomass-based resource requi...

The present work aims at the chemical characterization of several non-woody fibers from herbaceous plants used for manufacturing high quality paper pulps, with especial emphasis in the composition of lignin and lipophilic compounds. Among the fibers studied are bast fibers from flax, hemp, kenaf and jute and leaf fibers from abaca and sisal. Flax and hemp showed the lowest lignin content (< 5%)...

A bile acid:3'phosphoadenosine-5'phosphosulfate:sulfotransferase (BAST I) from adult female rat liver cytosol has been purified 157-fold by a two-step isolation procedure. The N-terminal amino acid sequence of the 30,000 subunit has been determined for the first 35 residues. The Vmax of purified BAST I is 18.7 nmol/min per mg protein with N-(3-hydroxy-5 beta-cholanoyl)glycine (glycolithocholic ...

Abstract The aim of this paper is to investigate biodegradation properties PLA (as a bio-based polymer), Hemp, Jute natural bast fibers) and Viscose cellulose regenerates) for agrotextile nonwovens production. For the purpose those investigations, an analysis time samples were performed by soil burial test (ISO 11721 – Textiles Determination resistance cellulose-containing textiles microorganis...

In recent years, there has been a growing awareness and demand for global sustainability, as well mandate the use of renewable environmentally sustainable materials processes. Due to which, massive efforts are being made develop nurture next generation composite that energy efficient, friendly, biodegradable. Light weight, lower coefficient thermal expansion, comparable tensile strength exhibit...

Hemp bast fibers were degummed using combined microwave energy (MWE) and deep eutectic solvent (DES) to generate pure hemp cellulose for potential textile applications. The properties of the investigated compared with those alkali-treated several analytical techniques. Results revealed that fiber surface underwent dramatic structural disruption during pretreatment, due removal “gummy” compounds...

In plants there is no universal protocol for RNA extraction, since optimizations are required depending on the species, tissues and developmental stages. Some plants/tissues are rich in secondary metabolites or synthesize thick cell walls, which hinder an efficient RNA extraction. One such example is bast fibres, long extraxylary cells characterized by a thick cellulosic cell wall. Given the ec...

 A case study is presented in which two modifications of activated sludge treatment of complex chemical wastewater are experimentally compared: a combination of common activated sludge with powdered activated carbon treatment (PACT), and bioaugmentation of activated sludge treatment (BAST). Industrial wastewater of Pars Oil Refinery that was passed through an oil recovery stage was used to inve...

Natural fiber composite is the novel materials in recent decades having a high strength to weight ratio and light are widely used for structural unstructured applications. Jute one of most common biodegradable natural fibers which successfully replaced synthetic also glass where not obliged. grown tropical countries strongest bast with low cost. has several attractive advantages over like as pr...
