Biofuels From Food Waste : Applications of Saccharification Using Fungal Solid State Fermentation

"According to the UN's Food & Agricultural Organization (FAO), one third of food produced globally for human consumption (nearly 1.3 billion tons) is lost annually. Food waste has often been incinerated with other combustible municipal wastes for possible recovery of heat or other forms of energy, however, incineration is not cost-effective, and can cause air pollution. Due to its organics- and nutrient-rich nature, food waste could be viewed as a useful resource for production of high-value platform chemicals through fermentation. This book examines the bioconversion of food wastes to energy and the recent developments in ethanol, hydrogen, methane, and biodiesel production from food wastes."--Provided by publisher Cover -- Half Title -- Title Page -- Copyright Page -- Contents -- Author -- Chapter 1: Bioconversion of Food Wastes to Energy -- 1.1 Introduction -- 1.2 Ethanol Production -- 1.2.1 Pretreatments -- 1.2.2 Saccharification -- 1.2.3 Process Configurations -- 1.2.4 Other Strategies to Improve Ethanol Yield -- 1.2.5 Large-Scale Ethanol Production from Food Waste -- 1.3 Hydrogen Production -- 1.3.1 Substrate Composition -- 1.3.2 Pretreatments -- 1.3.3 Process Configurations -- 1.4 Methane Production -- 1.4.1 Single-Stage Anaerobic Digestion -- 1.4.2 Two-Stage Anaerobic Digestion -- 1.4.3 Reactor Configurations -- 1.5 Biodiesel Production -- 1.6 Conclusions -- Chapter 2: Platform Chemical Production from Food Wastes -- 2.1 Introduction -- 2.2 Platform Chemical Production -- 2.2.1 Lactic Acid -- 2.2.2 Citric Acid -- 2.2.3 Succinic Acid -- 2.2.4 Polyhydroxyalkanoates -- 2.2.5 Single Cell Oils -- 2.2.5.1 Single Cell Oil Production Using Hydrophilic Feedstock -- 2.2.5.2 Single Cell Oil Production Using Hydrophobic Feedstock -- 2.3 Other Chemicals -- 2.4 Conclusions -- Chapter 3: Enzyme Production from Food Wastes -- 3.1 Introduction -- 3.2 Enzyme Production -- 3.2.1 Amylases -- 3.2.2 Lignocellulolytic Enzymes -- 3.2.3 Pectinolytic Enzymes -- 3.2.4 Proteases -- 3.2.5 Lipases -- 3.3 Conclusions -- Chapter 4: Enhanced Glucoamylase Production by Aspergillus awamori Using Solid State Fermentation -- 4.1 Introduction -- 4.2 Materials and Methods -- 4.2.1 Materials -- 4.2.2 Methods -- 4.2.2.1 Effect of Particle Size on Solid State Fermentation -- 4.2.2.2 Experimental Design for Enzyme Production -- 4.2.2.3 Solid State Fermentation and Enzyme Extraction -- 4.2.2.4 Glucoamylase Assay -- 4.2.2.5 Statistical Analysis -- 4.2.2.6 Model Validation -- 4.2.2.7 Analytical Methods -- 4.3 Results and Discussion
