We are investigating a novel application of a thermally-tolerant plant pectin methylesterase (TTPME) to improve energy efficiency in sugar beet processing. Sucrose diffusion from cossettes occurs in water heated to about 70°C, the optimal temperature for TT-PME activity. Drying pulp is necessary to stabilize it for storage and commercialization as animal feed, but this consumes up to 30% of tot...

Comparative study on organosolv pulping method have been done by using various mixtures of water and organic solvents as delignifying agents including ethylene glycol-water mixtures, ethanol-water mixtures and acetic acid-water mixtures to extract cellulose from agricultural crop biomass (Oil palm empty-fruit bunches-OPFB). The yield of organosolv pulping with ethylene glycol-water mixture, eth...

Regeneration (revitalization) of infected necrotic pulp tissue has been an important issue in endodontics for more than a decade. Based on a series of case reports, there appears to be evidence that new soft tissue can enter the root canal with a potential for subsequent hard tissue deposition resulting in a narrowing of the root canal. Very little is presently known about the exact nature of t...

Direct application of dentin bonding agents onto the exposed pulp has been advocated, but in vivo studies indicate a lack of reparative dentin formation. Our objective was to investigate the role of triethylene glycol dimethacrylate (TEGDMA), a commonly used compound in dentin bonding agents, as a potential inhibitor of mineralization. Human pulp cells were exposed to different concentrations o...

Vitality of dental pulp is essential for long-term tooth survival. The aim of vital pulp therapy is to maintain healthy pulp tissue by eliminating bacteria from the dentin-pulp complex. There are several different treatment options for vital pulp therapy in extensively decayed or traumatized teeth. Pulp capping or pulpotomy procedures rely upon an accurate assessment of the pulp status, and car...

This study aimed to investigate the in vitro biological response of human dental pulp cells to glass ionomer cement (GIC, Fuji IX GP(®)) containing 2.5% magnesium carbonate apatite (MgCO(3)Ap). MgCO(3)Ap was synthesized by wet method and characterized using FT-IR, XPS, and SEM. Fuji IX GP(®) served as a control. Test and control cements were prepared by encapsulated mixing the powder with Fuji ...

enzymatic deinking has been suggested as an environmentally friendly alternative to complement and replace for conventional chemical deinking. in the present research, the effect of hemicellulase from aspergillus niger has been evaluated on paper quality of mixed 70% old newspaper (onp) and 30% old magazine (omg) pulp. hemicellulose was used at different charges of 0.1 (h1), 0.2 (h2), 0.5 (h3) ...

Anaerobic digestion of biosludge has not yet been implemented in pulp mills due to low biogas yields. Enzymatic pretreatment of biosludge has shown improvements in biogas yields but results are varied. A key limitation of previous studies is that they fail to consider the COD contribution from the enzyme solutions. The aim of this study was to systematically investigate the potential for enzyma...
