MLT microbiology (Questions with 100% correct solutions)

Autotrophs correct answers organisms that produce organic compounds from carbon dioxide as a carbon source, using either light or reaction of inorganic chemical compounds as a source of energy Phototrophs correct answers autotrophs that use photosynthesis to feed Chemolithotrophs correct answers autotrophs that obtain energy by oxidation of inorganic compounds Heterotrophs correct answers organisms that requires organic substrates as a source of carbon for growth and development Fastidious correct answers hard to grow, requires additional growth factors Psychrophiles correct answers bacteria that grow best at cold temperatures (optimal growth at 10°C to 20°C) Mesophiles correct answers an organism that grows best in moderate temperature neither hot nor cold ( 25°C to 40°C) Thermophiles correct answers bacteria that grow best at high temperatures (optimal growth at 50°C - 60°C) Obligate aerobes correct answers a microorganism that requires oxygen for growth Obligate anaerobes correct answers a microorganism that can live and reproduce only in a strict anaerobic environment (0% oxygen) Facultative anaerobes correct answers a microorganism that does not require oxygen for growth but will use oxygen and grow better if it is present Capnophilic correct answers term used to describe microorganisms that require an increased concentration of CO², usually between 5% and 10% Microaerophilic correct answers microorganism that grows with reduced oxygen and increased carbon dioxide Minimal media correct answers a laboratory growth medium whose contents are simple and completely defined; not usually used in the diagnostic microbiology laboratory Nutrient media correct answers culture media that are complex and made of extracts of meat or soybeans
