In chemistry, the term "turnover number" has two distinct meanings.. In enzymology, the turnover number (k cat) is defined as the limiting number of chemical conversions of substrate molecules per second that a single active site will execute for a given enzyme concentration [E T] for enzymes with two or more active sites. [1]
With continued increase in temperature, performance decreases rapidly (Q 10 of 0.2-0.8) up to a maximum temperature at which all biological function again ceases. [5] Within vertebrates, different skeletal muscle activity has correspondingly different thermal dependencies.
The catalase test tests whether a microbe produces the enzyme catalase, which catalyzes the breakdown of hydrogen peroxide. Smearing a colony sample onto a glass slide and adding a solution of hydrogen peroxide (3% H 2 O 2) will indicate whether the enzyme is present or not. Bubbling is a positive test while nothing happening is a negative result.
Production of lignin-peroxidase and manganese-peroxidase is the hallmark of basidiomycetes and is often used to assess basidiomycete activity, especially in biotechnology applications. [38] Most white-rot species also produce laccase, a copper-containing enzyme that degrades polymeric lignin and humic substances.
Superoxide dismutase (SOD, EC 1.15.1.1) is an enzyme that alternately catalyzes the dismutation (or partitioning) of the superoxide (O − 2) anion radical into normal molecular oxygen (O 2) and hydrogen peroxide (H
The IMViC tests are a group of individual tests used in microbiology lab testing to identify an organism in the coliform group.A coliform is a gram negative, aerobic, or facultative anaerobic rod, which produces gas from lactose within 48 hours.
Lancefield grouping is a system of classification that classifies catalase-negative Gram-positive cocci based on the carbohydrate composition of bacterial antigens found on their cell walls. [1]
