By a News Reporter-Staff News Editor at Life Science Weekly -- A new study on Enzymes and Coenzymes is now available. According to news reporting out of Tabriz, Iran, by NewsRx editors, research stated, "The aims of the study were to investigate the effect of polyvinyl alcohol (PVA), carboxymethyl cellulose (CMC) and sodium montmorillonite clay (MMT-Na) content within the starch (S) blends on the rate and extent of starch enzymatic hydrolysis using enzymes alpha-amylase and cellulase. The results of this study have revealed that blends with MMT-Na content at 5 wt% exhibited a significantly reduced rate and extent of hydrolysis."
Our news journalists obtained a quote from the research from the University of Tabriz, "The results suggest that this may have been attributed to interactions between PVA S/CMC and MMT-Na that further prevented enzymatic attack on the remaining PVA/MMT-Na phases within the blend. The total solids remained after 4320 min were 48.54 wt% (PVA/S/CMC); 53.21 wt% (PVA/S/CMC/1% MMT); 55.84 wt% (PVA/S/CMC/3% MMT); 56.98 wt% (PVA/S/CMC/5% MMT). The rate of glucose production from each nanocomposite substrates was the rapidest for the substrate without MMT-Na and decreased with the addition of MMT-Na, for PVA/S/CMC blend (85.59 mu g/mlh), 74.24 mu g/ml h (PVA/S/CMC/1% MMT), 63.24 mu g/ml h (PVA/S/CMC/3%MMT) and 61.74 mu g/ml h for (PVA/S/CMC/5% MMT). The rate of hydrolysis was the rapidest for the substrate PVA/S/CMC and decreased enzymatic degradation behavior of sodium montmorillonite-containing nanocomposites of PVA/CMC with starch was based on the determinations of weight loss and the reducing sugars."
According to the news editors, the research concluded: "The degraded residues have been examined by FT-IR spectroscopy and scanning electronic microscopy (SEM) and UV-vis spectroscopy."
