“…The initial phase was rapidly followed by a second stage of equilibrium attainment. The equilibrium stage considers the state where no change has been observed between the amount of enzymes being adsorbed onto the carrier and the amount of enzymes desorbed from the carrier [9] .…”

“…Cellulase immobilization onto coffee carrier was found to be optimal under the temperature of 45 °C. Lv et al (2013) noted that the amount of enzyme amylase adsorbed onto the adsorbents originated from corn stalks core material has been temperature affected too, and reached a maximum at 36 °C [9] . On contrary, Prieto et al (2014) found that the amount of enzyme β- galactosidase adsorbed by mass unit of the commercial activated carbon decreased with the increase of temperature from 25 to 50 °C [24] .…”

“…The supports, which were employed, have originated from either synthetic or biological materials. Although synthetic materials are efficient at recognizing and binding of molecular targets, they are difficult to obtain and require more additional costs than bio-macromolecules [9] . Therefore, this investigation has been focused on a production of a suitable enzyme immobilization carrier, derived from an agroindustrial waste material, named spent coffee grounds, in order to develop cost-effective biocatalyst preparations for industrial use.…”

This study has explored the feasibility of using spent coffee grounds as a good supporting material for the Paenibacillus chitinolyticus CKS1 cellulase immobilization. An optimal operational conditions in a batch-adsorption system were found to be: carrier mass of 12 g/L, under the temperature of 45 °C and no pH adjustments. The immobilization yield reached about 71%. An equilibrium establishment between the cellulase and the carrier surface occurred within 45 min, whereas the process kinetics may be predicted by the pseudo-second-order model. An immobilized cellulase preparation expressed very good avicelase activity, this reached up to 2.67 U/g, and revealed an improved storage stability property, compared to free enzyme sample counterpart. The addition of metal ions, such as K+ and Mg2+ did not affect positively immobilization yield results, but on the contrary, contributed to an improved bio-activities of the immobilized cellulase, thus may be employed before each enzyme application. The method developed in this study offers a cheap and effective alternative for immediate enzyme isolation from the production medium and its stabilization, compared to other carriers used for the immobilization.

Abstract. Corn husk is one of the agricutural waste that has not been used optimally. corn husk waste allows to be used as immobilized support for biocatalyst because it is easy to obtain, available abundant, renewable and easy to decompose. This research was conducted in two phases, namely the adsorption of enzyme immobilization on the support, followed by crosslinking between the enzyme and support through the addition of glutaraldehyde. The optimum conditions for cross-linked adsorption immobilization using support of corn husk were achieved at concentrations of 0,75 mg / ml at 4 hour reaction time. The biggest unit activity value is obtained at 2,37 U / g support through 0.5% glutaraldehyde addition.

“…Corn stalk is an abundant agricultural waste, which is renewable and low cost. It is made up of a cortex and a core, and the cortex is mainly made up of cellulose and lignin and the CSC is mainly hemi-cellulose and a little lignin and cellulose [22]. Different parts of the biomass would produce different texture morphology.…”

Hierarchical porous activated carbon (AC) was obtained from corn stalk pith with a hierarchical macroporous nature, which is composed of cells of soft and spongy texture. The high specific surface area (2495 m 2 g-1) of the activated carbon (AC) was produced by the activation of corn stalk core (CSC) using potassium hydroxide at 700 °C. SEM, TEM and XRD were used to test the microstructure and crystallographic orientation of the carbon samples. The cyclic voltammetry, galvanostatic charge/discharge and electrochemical impedance spectroscopy were measured based on CSC-700. This sample had relatively low inner resistance of 1.0 Ω. The specific capacitance was 323 F g-1 in 6 mol L-1 KOH electrolyte at a current density of 0.1 A g-1 , and it still maintained very good cyclic stability with capacitance retention ratio of 97.9% (from 265.0 to 262.4 F g-1) at current density of 1.0 A g-1 for 1000 cycles.
