the expression of endoglucanase gene and protein profile belonging to two fungal species, penicillium oxalicum 1sms and trichoderma viride 156ms with high cellulase enzyme activity, was investigated. fungal isolates were cultured on inducer cmc medium and then the amount of released sugar and protein were assayed every three days for a month, using arsenate molybdatereagent and bradford method,...

Abstract Background Pulp refining is an energy consuming, but integral part of paper production with the aim to increase tensile strength and smoothness sheets. Commercial enzyme formulations are used lower requirements by pre-treatment pulp before refining. However, a high number different commercial products available on market containing enzymes varying origin composition, which complicates ...

The giant reed (Arundo donax) is a fast-growing plant adapted to different climatic and soil conditions; although its origin Asian, the species has spread throughout world. During development, it consumes three times more water than typical native vegetation responsible for changing landscape of riparian areas; high biomass productivity annual harvest period make this crop an alternative produc...

BACKGROUND Chlorophyte microalgae have a cell wall containing a large quantity of cellulose Iα with a triclinic unit cell hydrogen-bonding pattern that is more susceptible to hydrolysis than that of the cellulose Iβ polymorphic form that is predominant in higher plants. This study addressed the enzymatic hydrolysis of untreated Chlorella homosphaera biomass using selected enzyme preparations, a...

We characterized a multifunctional cellulase (CelAB) encoded by the endosymbiont Teredinibacter turnerae T7902(T). CelAB contains two catalytic and two carbohydrate-binding domains, each separated by polyserine linker regions. CelAB binds cellulose and chitin, degrades multiple complex polysaccharides, and displays two catalytic activities, cellobiohydrolase (EC 3.2.1.91) and beta-1,4(3) endogl...
