Abstract
Pectin gels and pectin-cellulose binary gels were used as cell wall-mimicking systems to investigate the diffusion ability of a fungal pectin methylesterase. Increasing content of cellulose in the gel appears to result: (i) in longer demethylated blocks thus favouring AaPME processivity, and (ii) in accelerated enzyme kinetics. To better understand this unexpected behaviour, a method was set up to investigate the gel porosity as a function of the cellulose content by following the passive diffusion of three pullulans having different hydrodynamic volumes. Like the enzyme, the pullulans diffused more efficiently in the gels containing the highest proportions of cellulose. Altogether, these results suggest that the gel settled differently during formation according to the respective proportions of the two polysaccharides. With cellulose present, a fraction of pectin would form close interactions with the microfibrils resulting in a larger volume accessible to diffusing molecules. This volume would be related to the cellulose concentration.

Abstract
β-agarase activity was monitored by traditional reducing sugar content methods: Somogyi-Nelson's arsenomolybdate, Miller's dinitrosalicylic acid and Kidby and Davidson's ferricyanide methods, as well as by high-performance size exclusion chromatography coupled with a refractive index detector and an evaporative light scattering detector (ELSD). Calibration curves were established separately for each method to measure the amounts of the neoagaro-oligosaccharides (NAOS) in the reaction mixtures, which are the products from 1-10 units (U) of β-agarase cleavage activity on agarose. Product quantities from each monitoring method were compared with the isolated NAOS products. The graphs plotted by agarase activity unit and product concentration clearly displayed that the ELSD method closely followed the results of the isolated products. The percentage deviation of results measured by the five methods away from those of the isolated NAOS product mixture amounted to -13.1-35.1, -21.1-25.5, -27.1-23.81, 6.1-24.3 and 16.2-22.8%, respectively. When the loss during product isolation, about 15-17%, was taken into account, the high precision of the ELSD method was confirmed. HPSEC-ELSD methods also accurately measured the enzyme kinetics as well as enabling partial identification of oligosaccharides assembled in the NAOS product mixture. This study established the HPSEC-ELSD system as an alternative method for monitoring agarase activity.

Abstract
The recombinant amylosucrase from Neisseria polysaccharea was used to synthesize in vitro amylose from sucrose as unique substrate. The morphology and structure of the insoluble residue were shown to depend only on the initial sucrose concentration (100, 300, or 600 mM), which controlled both the chain length and concentration at the precipitation stage. The average degree of polymerization (DP) in the precipitated product varied from 58 for the lowest initial sucrose concentration (100 mM) to 45 and 35 for higher sucrose concentrations (300 and 600 mM, respectively). The shorter chains (DP 35 and 45), produced in high yields (54 and 24 g/L respectively), precipitated as polycrystalline aggregates with exceptional crystallinity, without optimization of the reaction medium for crystallization. The longer chains (DP 58), produced in lower amount (2.9 g/L), formed networks similar to those observed for amylose gels. All synthesized products displayed a B-type crystal structure. Their melting behavior was also studied, the thermostability being higher for the precipitate containing the longer chains. Further thermal treatments were shown to still improve the crystallinity and yield substrates usable as new standards for the determination of the relative crystallinity of starchy products. The kinetics of chain elongation and aggregation were thoroughly investigated in order to explain how the action of amylosucrase resulted in such different amylose structures. These results emphasize the potentiality of amylosucrase in the design of amylodextrins with controlled morphology, structure, and physicochemical properties.
