"Biopolymers can provide environmentally friendly alternatives to the use of fossil fuel derived polymers. Among others, their production can be net carbon negative and their disposal can help fertilizing soil by composting. However, the environmental benefits of these biopolymers are largely untapped as their overall production capacity is marginal. This low production is primarily caused by their high production cost and selling price, which hinder most biopolymers to compete on the market. One of the most promising, yet expensive biopolymers are the microbiologically produced polyhydroxyalkanoates (PHAs), since they are compostable and also biodegrade in the marine environment. Furthermore, the currently used raw materials for their production (corn starch and vegetable oils) are not only expensive, but also compete with food production. Alternatively, in Canada, wood is abundantly available through the pulp and paper infrastructure, with residues which can be fed to modern biorefineries. This work explores the feasibility of integrating the most well-known PHA, polyhydroxybutyrate (PHB), into forest biorefineries using the bacterium Paraburkholderia sacchari.For this work, the first forest biorefinery scheme was based on the hydrolysis of softwood hemicellulose as a feedstock for PHB production. Softwood cellulose and lignin were recovered to be further converted into other products. Softwood hemicellulose has a favourable composition as compared to most other hemicelluloses, as it has a high share of the six carbon sugars mannose, glucose and galactose. Mannose and galactose were tested as carbon sources for P. sacchari for the first time and showed maximum specific growth rates of 97% and 60% relative to glucose, respectively. However, the presence of inhibitory compounds (acetate, 5 hydroxymethylfurfural, furfural and phenols) inhibited all bacterial growth. It was found that the inhibition comes from strong synergistic effects when the inhibitors are present in mixtures, and the magnitude of the effects was quantified with a mixture design model. Albeit the initial inhibition could be overcome by a high initial cell density (optical density ≥ 5.6) when using a simulated softwood hemicellulose hydrolysate, this approach was not successful for real softwood hemicellulose hydrolysate. Nevertheless, when the hydrolysate was added as a feed solution after an initial growth phase of 24 h, the sugars were all consumed. In comparison with an inhibitor-free hardwood hydrolysate, the growth rate and PHB yield were lower with softwood hemicellulose hydrolysate. While the sugar composition of the hydrolysate was therefore promising for PHB production, the inhibitory effect currently makes it unsuitable as the carbon source.The second biorefinery scheme studied was based on a pilot plant process developed by FPInnovations using hardwood biomass. The process converts hardwood cellulose and hemicellulose into a holocellulose hydrolysate, which was used as carbon source for PHB production. Using this hardwood hydrolysate in shake flask fermentations increased the maximum specific growth rate and PHB accumulation of the bacterium as compared to simulated hydrolysates. In high-cell density bioreactor fermentations, the wood hydrolysate afforded one of the highest PHB concentrations to date from lignocellulosic biomass. The chemical composition, thermal transitions and viscoelastic properties were similar to literature values of PHB. The number average molecular mass was 246.4 kDa with a PDI of 3.29. These results make PHB from hardwood hydrolysate, as co product with H lignin, a sustainable production scheme for industrial PHB production"--

Sets the stage for large-scale production of biofuels and bio-based chemicals In response to diminishing supplies as well as the environmental hazards posed by fossil fuels and petrochemicals, interest and demand for green, sustainable biofuels and bio-based chemicals are soaring. Biomass may be the solution. It is an abundant carbon-neutral renewable feedstock that can be used for the production of fuels and chemicals. Currently, biorefineries use corn, soybeans, and sugarcane for bioethanol and biodiesel production; however, there are many challenges facing biorefineries, preventing biomass from reaching its full potential. This book provides a comprehensive review of bioprocessing technologies that use lignocellulosic biomass for the production of biofuels, biochemicals, and biopolymers. It begins with an overview of integrated biorefineries. Next, it covers: Biomass feedstocks, including sugar, starch, oil, and energy crops as well as microalgae Pretreatment technologies for lignocellulosic biomass Hydrolytic enzymes used in biorefineries for the hydrolysis of starch and lignocelluloses Bioconversion technologies for current and future biofuels such as ethanol, biodiesel, butanol, hydrogen, and biogas Specialty chemicals, building block chemicals, and biopolymers produced via fermentation Phytochemicals and functional food ingredients extracted from plant materials All the chapters have been written and edited by leading experts in bioprocessing and biorefining technologies. Contributions are based on a thorough review of the literature as well as the authors' firsthand experience developing and working with bioprocessing technologies. By setting forth the current state of the technology and pointing to promising new directions in research, Bioprocessing Technologies in Biorefinery for Sustainable Production of Fuels, Chemicals, and Polymers will enable readers to move towards large-scale, sustainable, and economical production of biofuels and bio-based chemicals.

The interest in biofuel production and application is governed by the depletion of fossil fuel resources and the threatening pollution of the atmosphere because of the extensive emissions of greenhouse gases, which the present global vegetation cannot cope with. A remedy against the greenhouse gas emissions is the use of biomass presently grown as a source for biofuels. Biofuels can be further utilized as substrates for bulk chemical products. This approach is known as the biorefinery concept as an analogue to the oil-based refineries.The present book offers some examples and new ideas for the broader applications of biofuels and the resulting raw materials for energy and chemical products as alternatives to the traditional fossil fuels.
