Micro

(A)nutrition process by which chemical substances (nutrients) are acquired from the environment and sacrifice for cadreular activities requirement nutrients - must be provided to an organism Two categories of all important(p) nutrients: macronutrients need in large quantities; play principal roles in cell structure and metabolic process .proteins, carbohydrates micronutrients or trace elements compulsory in small summations; involved in enzyme function and guardianship of protein structure.manganese, zinc, nickel Chemical Analysis of Microbial Cytoplasm 70% water-Proteins-96% of cell is composed of 6 elements: Carbon-hydrogen- atomic number 8-phosphorous-sulfur-nitrogen (B) aliment requirements- Carbon sources- Environmental factors basically affect the function of metabolous enzymes:Factors include: Temperature.oxygen requirements.pH.electromagnetic radiation.barometric closet Temperature Adaptation Groups-Psychrophiles glacial opt imum temperature at a lower repose 15oC; capable of contractth at 0oC Mesophiles minor body temperature. optimum temperature 20o-40oC; some human pathogens Thermophiles Heat loving. optimum temperature greater than 45oC.Hyperthermophiles- very baking loving, boiling or in a higher place temp Effects of pH: acidophiles grow at utmost(prenominal) acid pH below 5.

5 Alkalinophiles grow at extreme alkalic pH above 8.5 Neutrophiles neutral PH around 7 (Note) These ph ranges are critical true fir cellular region due to their effect on metabolism and enzyme functions Oxygen Requirement: Aerobe utilizes oxygen and heap detoxify it stimulate aerobe - cannot grow without oxygen Facultative anaerobe utilizes oxygen but c! an also grow in its absence Microaerophilic requires only a small amount of oxygen.Capnophile grows best at higher carbon dioxide tensions than approach patternly defend in the atmosphereBarophiles can survive chthonic extreme pressure and will rupture if exposed to normal atmospheric pressure dependent ( microbial relationship) organisms live in close nutritional...If you want to yield a full essay, golf-club it on our website: OrderEssay.net
