Torrefaction is a thermochemical process, where biomass obtained in temperature range from 200 to 300 °C, inert atmosphere with the aim increase carbon content of biomass. In this paper, emphasis on feedstock types, different effects torrefaction success, and reactors.

Microalgae harvesting by coagulation can use coagulant agents such as alum, synthetic polymers or biocoagulants. Biocoagulants have attracted the attention of researchers because they are natural, biodegradable, and promote high microalgal efficiencies. This study aims to optimize Chlorella vulgaris based on dosage Opuntia cochenillifera extract choice eluent for biopolymer extraction. The outd...

Today, biofuels represent a hot topic in the context of petroleum and adjacent products decrease. As biofuels production increase, so does the production of their major byproduct, namely crude glycerol. The efficient usage of raw glycerol will concur to the biodiesel viability. As an inevitable waste of biodiesel manufacturing, glycerol is potentially an attractive substrate for the production ...

We present an integrated design and marketing approach to facilitate the generation of an optimal robust set of product design alternatives to carry forward to the prototyping stage. The approach considers variability in both (i) engineering design domain, and (ii) customer preferences in marketing domain. In the design domain, the approach evaluates performance and robustness of a design alter...

Developing innovative bioprocess strategies for carbon capture and utilization has been a major focus of research over the past decade as way creating more resilient world. In this study, zero-valent iron (ZVI) was utilized to generate hydrogen, which then an electron donor CO2 reduction by either Clostridium aceticum or carboxidivorans. For bioprocess, early acidic condition in reactors facili...

Recent progress in the measurement of the bioconversion of dietary provitamin A carotenoids to vitamin A is reviewed in this article. Methods to assess the bioavailability and bioconversion of provitamin A carotenoids have advanced significantly in the past 10 y, specifically through the use of stable isotope methodology, which includes the use of labeled plant foods. The effects of the food ma...

BACKGROUND Bioconversion of D-galacturonic acid to galactaric (mucic) acid has previously been carried out in small scale (50-1000 mL) cultures, which produce tens of grams of galactaric acid. To obtain larger amounts of biologically produced galactaric acid, the process needed to be scaled up using a readily available technical substrate. Food grade pectin was selected as a readily available s...
