bio gas Co-digestion of Biomass for Methane Production: Recent Research Achievements Wei Wu ABSTRACT Anaerobic digestion (AD) is a process by which microorganisms break down biodegradable material in the absence of oxygen. Anaerobic digestion can be used to treat various organic wastes and recover bio-energy in the form of biogas‚ which consists mainly of CH4 and CO2. A great option for improving yields of anaerobic digestion of solid wastes is the co-digestion of multiple substrates. Numerous

metabolized in the body! Digestion is the chemical breakdown of food molecules into smaller molecules that can be used by various cells within the body. The breakdown is initiated when food is ingested in the mouth and specific enzymes are exposed to components within the food molecules. Digestion begins in the mouth with mastication‚ or chewing‚ performed by the teeth. The purpose of chewing is to grant the food more exposure to enzymes‚ therefore allowing chemical digestion to occur faster. The presence

Define the following terms: Digestion: Digestion is the breakdown of large insoluble food substances in small and soluble one by means of mechanical and chemical actions. Peristalsis: It is a series of alternate contraction and relaxation of the circular and longitudinal muscles‚ producing a wave-like motion to move food down the oesophagus‚ from the mouth to the stomach. Emulsification: It is the hydrolysis of a few large fat globules into many small and soluble fat molecules. Transpiration:

Observation of Digestive and Circulatory System Introduction/Background: This week’s lab is about digestion and the circulatory system. Students will be learning about the different types of digestion and circulatory systems for different types of animals. Students will learn not only about the mechanical and chemical components of digestion‚ but also the complete and incomplete digestions. The lab will also teach the open and closed‚ single and double‚ circulation patterns. Several different models

Digestion and Enzymes – APP. Hypothesis: The enzyme‚ Amylase which is used to break down carbohydrates will work the best when heated at 40°C. Also‚ as the temperature increases the reaction rate of amylase increases too. However‚ the reaction rate of amylase will start decreasing when the temperature reaches the enzyme’s optimal temperature. Many enzymes are specific for a certain substrate. For example‚ lipase is a specific enzyme for fat substrates and protease‚ a specific enzyme for
