Factors Affecting Growth of Microorganisms pp presentation Maintaining work equipment and the physical state of a building is important, but there are potential threats lurking in a company’s infrastructure that are too small for the naked eye to see. Factors can be divided into four groups: physicochemical properties of the food, conditions of the storage environment, interactions of microorganisms, and process factors such as physical treatments and addition of chemicals. Bacteria have a minimum, optimum, and maximum temperature for growth and can be divided into 3 groups based on their optimum growth temperature: psychrophils, mesophils, thermophils, or hyperthermophils. PH 4. 3. Many are downloadable. 2. Growth factors are organic compounds such as amino acids , purines , pyrimidines , and vitamins that a cell must have for growth but cannot synthesize itself.

Presentation Summary : Factors that affect microbial growth are: Intrinsic factors: Factors inherent to the food. Learn new and interesting things. Growth of microorganisms in food is dependent on various parameters. Osmotic pressure (salt tolerance). Bacteria grow only in the presence of oxygen, called: strict aerobes. Temperature requirement. Environmental factors that affect plant growth include light, temperature, water, humidity, and nutrition. 2. Factors affecting microbial growth FACTORS AFFECTING GROWTH … With a basic understanding of these factors, you may be able to manipulate plants to meet your needs, whether for increased leaf, flower, or fruit production. The intrinsic and extrinsic factors affecting the growth of microorganisms in food are explained below: Factors Affecting Microbial Growth In Foods By Afolabi, O.r. Factors limiting bioremediation technologies R. Boopathy Department of Biological Sciences, Nicholls State University, Thibodaux, LA 70310, USA Abstract The use of microorganisms to destroy, or reduce the concentration of, hazardous wastes on a contaminated site is called bio-remediation. Different organisms react to their environment in different ways. The genetic factor is also called internal factor because the basis of plant expression (the gene) is located within the cell. Heredity. The factors can be generally classified as intrinsic and extrinsic factors. It is important to understand how these factors affect plant growth and development. Gibberelins Role in Stem Elongation and Germination. Extrinsic BACTERIAL GROWTH AND MICROBIAL METABOLISM. The factors affecting your child’s growth and development can be broken down into many smaller aspects to take note. These factors can be broadly classified into five.
