Anaerobic digestion Anaerobic digestion is a series of processes in which microorganisms break down biodegradable material in the absence of oxygen‚ used for industrial or domestic purposes to manage waste and/or to release energy. The digestion process begins with bacterial hydrolysis of the input materials in order to break down insoluble organic polymers such as carbohydrates and make them available for other bacteria. Acidogenic bacteria then convert the sugars and amino acids into carbon dioxide

a universal method of identifying bacteria allows for all scientists from any part of the world to identify the same species in an identical manner allowing for a precise of classification. Bacteria are distributed throughout the world in almost every conceivable habit. Bacteria are unicellular microorganisms‚ with variable shapes and nutritional needs. They lack a distinct nucleus and occur singly or in chains or clusters and form distinct colonies. Bacteria are classified on the basis of many

Bacterial Smears Are Fixed before Staining to? Answer It is important to heat fix the bacterial smear before staining so as to‚ kill the bacteria‚ firmly adhere the smear on to the microscopic slide to prevent washing off during staining‚ and to allow the sample to readily take up the stain. Reference: www2.hendrix.edu What is the purpose of heat- fixing the smear? It helps the cells adhere to the slide so that they can be stained. The purpose of heat fixing is to kill the organisms without

INTRODUCTION Cellular respiration is a biochemical pathway in which cells produce ATP or energy and carbon dioxide as metabolic waste by breaking down the chemical bonds of food molecules. Cellular respiration is a type of aerobic respiration which needed oxygen in order to produce ATP which occurring in the mitochondria. Meanwhile‚ in the absence of oxygen‚ the cells will undergo anaerobic respiration to produce ATP in the cytoplasm. Anaerobic respiration can be divided into two parts which are

“Fighting Invisible Killers” Scholastic Scope: The Language Arts Magazine January 2014 Edition‚ pages 5-9 Bacteria surround us every day. These little “bugs” are invisible to the eye and most do not harm us. Many are necessary for us to survive‚ like the bacteria in our stomachs and intestines that help us to digest food. But some bacteria are very dangerous to us. Addie Rereich became very sick in May 2011‚ when she was 11 years old. What started as something that her doctors and mother

Bacteria are the most numerous type of microorganism found in the rhizosphere of the soil. They produce secondary metabolites which are capable of producing antibiotic which eventually inhibit or kill bacteria. The rhizosphere region of the soil is a highly favorable habitat for the proliferation‚ activity and metabolism of numerous microorganisms. The magnitude of this area depends on the plant and the size of the roots that the plant possesses. Bacteria are among the microorganisms living in the
