Bioenergy is a type of renewable energy made from biological sources including algae, trees, or waste from agriculture, wood processing, food materials, and municipalities. Currently, the uses of renewable fuels (bioethanol, biodiesel, biogas and hydrogen) are increased in the transport sector worldwide. From an environmental and resource-efficiency perspective biogas has several advantages in ...

Pulsed electric field (PEF) processing uses short, high-voltage electrical pulses and a specially designed treatment chamber to permeabilize cellular membranes. There are at least two distinct applications of PEF to algal growth and processing – extraction of intracellular material and microalgae predator population control. PEF processing has the potential to provide lower costs and higher pro...

In the last five years or so, biofuels have been given notable consideration worldwide as an alternative to fossil fuels, due to their potential to reduce greenhouse gas emissions by partial replacement of oil as a transport fuel. The production of biofuels using a sustainable approach, should consider local production of biofuels, obtained from local feedstocks and adapted to the socio-economi...

Compared to traditional lignocellulose biomass, microalgae contain little or no lignin. Traditionally, bioethanol production from undergoes three major steps: (i) pretreatment; (ii) polysaccharides hydrolysis into simple sugars; and (iii) sugar conversion by fermentation. Microalgae convert sunlight, water, CO2 algal biomass. Diatoms, green algae, bluegreen golden algae are four main classes of...

Given that sustainable energy production and advanced wastewater treatment for producing clean water are two major challenges faced by modern society, microalgae make a desirable treatment alternative by providing a renewable biomass feedstock for biofuel production, while treating wastewater as a growth medium. Microalgae have been known to be resilient to the toxic contaminants of highly conc...
