1. An Alkaline Active Endo-Xylanase from Bacillus halodurans S7:Molecular and Structural Aspects
Abstract : A strain of an alkaliphilic bacterium Bacillus halodurans was isolated from a water sample in Lake Shalla, a soda lake in the Ethiopian Rift Valley. From the culture of this isolate, B. halodurans S7, a xylanase which is active in a wide range of pH, with an optimum at about 9-9.5 was purified. READ MORE

2. Enhanced Enzymatic Hydrolysis of Lignocellulose in Bioethanol Production Substrate Interactions with Surfactants and Polymers
Abstract : Ethanol produced from cellulose is a promising future alternative fuel. The production process has three main steps: (i) pretreatment of raw material to increase degradability; (ii) enzymatic hydrolysis of cellulose to produce glucose; (iii) fermentation of glucose into bioethanol.

3. Bench-Scale Production of Heterologous Proteins from Extremophiles- Escherichia coli and Pichia pastoris based expression systems
Abstract : Over the past few years considerable research attention has been assigned to extremophiles as sources of extremozymes due to their applicability in industrial processes, and the development of eco-friendly technologies. The establishment of efficient production strategies for heterologous proteins is an empirical process requiring broad background knowledge on available expression systems together with their major advantages and shortcomings.

4. SOUnd-DRIven BIOtechnology
Abstract : Ultrasound has been vastly applied in different areas such as medical imaging and the food industry, but not much attempt has been made to investigate its influence on microorganisms and its potential to be applied in microbial biotechnology. Previous studies show the potential of acoustic waves to increase biomass yield, production of secondary metabolites and enhanced enzyme-catalyzed reactions, probably due to improved mass transfer and cell retention.

5. Biorefining of lignocellulose : Detoxification of inhibitory hydrolysates and potential utilization of residual streams for production of enzymes
Abstract : Lignocellulosic biomass is a renewable resource that can be utilized for the production of biofuels, chemicals, and bio-based materials. Biochemical conversion of lignocellulose to advanced biofuels, such as cellulosic ethanol, is generally performed through microbial fermentation of sugars generated by thermochemical pretreatment of the biomass followed by an enzymatic hydrolysis of the cellulose.
