The pool of LMW DON turns over faster than HMW DON (Jones and Kiel land 2012), with
depolymerisation representing a bottleneck in addition to the potential formation of recalcitrant HMW DON molecules (Knicker 2004; Schimel and Bennett 2004).
Chondroitin Sulphate
Depolymerisation. Following concentration and dialysis, UTI fraction was diluted with 0.5 M ammonium acetate 5X buffer, pH8.0, and incubated overnight at 37[degrees]C with 0.025U of Chase-ABC (Sigma-Aldrich, MO, USA), allowing for chondroitin sulphate complete
depolymerisation into constituent disaccharide units with an unsaturation between C4 and C5 of hexuronic acid ([DELTA]-disaccharides).
These reactions include
depolymerisation, thermohydrolysis, intermolecular transesterification, intramolecular transesterification and cyclic oligomerization.
The disruptive
depolymerisation technology manufactures purified terephthalic acid and mono ethelyne glycol from waste Polyester/PET feedstocks.
2a-b) show a Si--O--Si (Si--O--Al) stretching band shifting to lower values of around 960 [cm.sup.-1] after 7 days and then back to higher values of 970-980 [cm.sup.-1] after 28 days, depicting the initial
depolymerisation and subsequent rearrangement of silicate bonds back into polymeric chains.
Enzymatic activities of soil can be stabilized by clay-humus complexes, which play a major significant role in the
depolymerisation of various polymeric macromolecules (Burns et al., 2013).

depolymerisation in ionic liquids," Green Chemistry, vol.
This loss of weight is ascribed to the dehydration of the saccharide rings,
depolymerisation, and decomposition of the acetylated and deacetylated units of adsorbent [32].
Under physioxia, intermediate filaments of ASCs formed nestlike structures, whereas hypoxia preconditioning promoted vimentin
depolymerisation (Figure 4(a)).

Depolymerisation, vol.
As a consequence,
depolymerisation of exopolysaccharides in response to NaI[O.sub.4] varies depending on biofilm components.
