Susceptibility of Saccharomyces cerevisiae to inhibitors and impact on bioethanol production yield
(PSRC, 2014)
There have been increasing concerns in developing countries over the competition between food and energy resulting from the production of bioethanol from edible biomass. Second generation lignocellulose feedstock is an ...
Comparative adaptation of B. subtilis and P. aeruginosa in diesel supplemented medium and impact on biodegradation potential
(PSRC, 2014)
The degree of diesel blending is likely to influence its toxicity as well as the susceptibility and speed of biodegradation. It is therefore imperative to identify strains that can degrade diesel blend in record time, such ...
Co-digestion of sweet sorghum bagasse with scientific and crude glycerols for electricity generation
(PSRC, 2014)
With the global fossil fuel supplies dwindling and the alarming increase of carbon dioxide in the atmosphere, the need for alternative, clean energies, from carbon neutral sources is pressing. This impetus advanced research ...
Bio-oil and bio-char production from sunflower hulls
(ETA-Florence Renewable Energies, 2011)
In this paper, the hydrothermal liquefaction of sunflower hulls into biooil and biochar is presented. The main manipulated variables that were studied were biomass load, catalyst type and temperature. The experimental ...
In-situ biodiesel production from sunflower seeds using liquefaction
(ETA-Florence Renewable Energies, 2015)
One of the most expensive steps in the bio-diesel value chain is the extraction of oil from the seeds. Simultaneous extraction and transesterification will lower the overall capital costs of the process while enhancing ...
Ultrasonic assisted amaranth stem pretreatment for bio-ethanol production
(ETA-Florence Renewable Energies, 2015)
An investigation was undertaken to determine the effect of ultrasound on enzymatic hydrolysis rate and enhanced bioethanol yields. Compositional analysis of the feedstock reveals that amaranth lignocellulose contains 36.35% ...
Separation of lignin from industrial prehydrolysis liquor using a solid acid catalyst
(ETA-Florence Renewable Energies, 2019)
The concept of a biorefinery has been introduced in the pulp and paper industry in order to improve the industry’s profitability and competitiveness by generating new revenues from new products. Prehydrolysis liquor (PHL) ...
Production of value-added products from biodiesel derived crude glycerol
(ETA-Florence Renewable Energies, 2015)
Crude glycerol, a by-product of biodiesel production which contain impurities such as methanol, triglycerides and catalysts, would represent a huge challenge to the environment if disposed. Thus the best opportunity is to ...
Preparation of biochars for co-gasification from sweet sorghum bagasse
(ETA-Florence Renewable Energies, 2015)
Biochar is a solid product obtained through torrefaction, liquefaction or pyrolysis of organic material. It can be used for soil amendment, activated carbon for sequestration, or as bio-coal for gasification or co-gasification. ...
Enhancement of bio-methane production by lignocellulose substrates
(ETA-Florence Renewable Energies, 2015)
In this study, water hyacinth, sweet sorghum bagasse and amaranth stems were used in a pig manure matrix to produce biogas with a high methane content. The anaerobic digestion was monitored over a period of 40 days, after ...
