Mild Alkaline Pretreatment of Rice Straw as a Feedstock in Microbial Fuel Cells for Generation of Bioelectricity.

The dependency on non-renewable fossil fuels as an energy source has drastically increased global temperatures. Their continuous use poses a great threat to the existing energy reserves. Therefore, the energy sector has taken a turn toward developing eco-friendly, sustainable energy generation by using sustainable lignocellulosic wastes, such as rice straw (RS).

Influence of Metal Ions on the Immobilization of β-Glucosidase Through Protein-Inorganic Hybrids.

Immobilization of enzymes through metal-based system is demonstrated as a promising approach to enhance its properties. In this study, the influence of metals ions, including copper, cobalt and zinc (Zn) on the immobilization of β-glucosidase (BGL) through the synthesis of protein-inorganic hybrid was evaluated at 4 °C. Among these metal ions-based hybrids, Zn showed the highest encapsulation yield and relative activity of 87.

Methanol production from simulated biogas mixtures by co-immobilized Methylomonas methanica and Methylocella tundrae.

In the present study, co-cultures of the methanotrophs Methylocella tundrae, Methyloferula stellata, and Methylomonas methanica were evaluated for improving methanol production with their application. Among the different combinations, the co-culture of M. tundrae and M.

Immobilization of Xylanase Using a Protein-Inorganic Hybrid System.

In this study, the immobilization of xylanase using a protein-inorganic hybrid nanoflower system was assessed to improve the enzyme properties. The synthesis of hybrid xylanase nanoflowers was very effective at 4°C for 72 h, using 0.25 mg/ml protein, and efficient immobilization of xylanase was observed, with a maximum encapsulation yield and relative activity of 78.
