Polyacrylamide as a substrate for microbial amidase

High molecular weight, linear polyacrylamide (PAM) with anionic charge is added to agricultural soils as an anti-erosion additive. Research indicates that soil microorganisms are able to utilize PAM as a source of N and that inorganic N pools are altered in some PAM-treated soils.

Isolation and Characterization of Polyacrylamide-Degrading

Polyacrylamide (PAM) is a water-soluble polymer that is widely used as a flocculant in sewage treatment. The accumulation of PAM affects the formation of dewatered sludge and potentially produces hazardous monomers. In the present study, the bacterial strain HI47 was isolated from dewatered sludge.

Desktop review of Polyacrylamide use in the Australian

[Executive Summary]: Polyacrylamide, commonly known as PAM, is a long-chain hydrocarbon of high molecular weight, synthesized from natural gas for a range of industrial and environmental use. In Agriculture, PAM and other polymers have been historically used as a soil conditioner similar to gypsum and lime. The purpose of this review is to establish the extent to which PAM is useful in

FIELD RESULTS USING POLYACRYLAMIDE TO MANAGE FURROW

One of the most effective treatments applied PAM at 10 g m 3 in irrigation inflows during the furrow advance period. This initial high-load treatment was nearly twice as effective as a continuous 0.25 g m −3 PAM application on these soils when slopes were 1–2%.

The PAM recoveries ranged from 95.8% to 103.7%, and the relative standard deviations (n = 4) were <7.5% in all cases. The optimum range of PAM in each sample is 10−80 μg.

PAM APPLICATION TECHNIQUES AND MOBILITY IN SOIL

Abstract High application rates (50–200 mg Kg −1 soil) and strong adsorption to soil aggregates severely limit polyacrylamide (PAM) application as a soil conditioner below the top soil. Limited penetration, 0 to 20 cm, was obtained upon introducing tritium-labeled PAM-2J into a clayey and sandy loam, respectively.
