Zinc Sorption Studies on Pectin-Based Biosorbents

The previously-obtained and characterized hybrid pectin-based beads containing agar-agar and guar gum, as well as sole pectin beads (P, for comparison) were examined for zinc ions sorption and desorption properties. The sorption kinetics and equilibrium in the studied system was described by two kinetic models (pseudo-first- and pseudo-second-order) and two isotherms (Langmuir and Freundlich), ...

Enzyme assay for identification of pectin and pectin derivatives, based on recombinant pectate lyase.

A simple method was developed for fast identification of pectin, based on a recombinant endopectate lyase cloned from Aspergillus niger. When pectin was demethylated and treated with pectate lyase, beta-elimination occurred, resulting in a double bond between C-4 and C-5 in the galacturonic acid residue of the released nonreducing end. The formation of double bonds produced an increase in light...

The pattern of distribution of pectin, peroxidase and lignin in the middle lamella of secondary xylem fibres in alfalfa (Medicago sativa).

BACKGROUNDS AND AIMS Information on the micro-distribution of lignin within the middle lamella is only just beginning to emerge. This paper provides evidence of marked heterogeneity in the micro-distribution of lignin, pectin, peroxidase and hydrogen peroxide in the middle lamella of alfalfa (Medicago sativa). METHODS Specimens from alfalfa stems were collected and processed for transmission ...
