What does laccase enzyme do?
Laccase is a multi-copper oxidase that catalyzes the oxidation of one electron of a wide range of phenolic compounds. The enzyme is considered eco-friendly because it requires molecular oxygen as co-substrate for the catalysis and it yields water as the sole by-product.
What are enzymes in microbiology?
An enzyme is a substance that acts as a catalyst in living organisms, regulating the rate at which chemical reactions proceed without itself being altered in the process. The biological processes that occur within all living organisms are chemical reactions, and most are regulated by enzymes.
Where does laccase come from?
Laccases are widely distributed in higher plants, bacteria, fungi, and insects. In plants, laccases are found in cabbages, turnip, potatoes, pears, apples, and other vegetables. They have been isolated from Ascomyceteous, Deuteromycteous and Basidiomycetous fungi to which more than 60 fungal strains belong .
What are enzyme producing bacteria?
Bacillus lentus is a bacteria that can produce various types of enzymes that can break down food substances such as carbohydrates, fats and proteins into simpler compounds that are easier to digest .
What are the main types of enzymes that bacteria produce?
Others include amylase, glucoamylase, xylose isomerase, lactase, lipase, cellulase, pullulanase, and xylanase. The food and feed industries are the largest customers for industrial enzymes. Over half of the industrial enzymes are made by yeasts and molds, with bacteria producing about 30%.
What is bacterial laccase?
Abstract. Laccases (benzenediol: oxygen oxidoreductase, EC 1.10. 3.2) are multi-copper enzymes which catalyze the oxidation of a wide range of phenolic and non-phenolic aromatic compounds in the presence or absence of a mediator.
Is laccase produced by bacteria?
Bacterial sources First, bacterial laccase, known as Azospirillum lipoferum, was isolated in the year 1993 from rice rhizosphere (Givaudan et al. 1993). Laccase has been produced from different bacteria that belong to different genera.
Are microbial enzymes bad for you?
The data showing no adverse effects for enzyme preparations also confirms that microbial metabolites and fermentation materials lack toxicity as well. Exposure to enzyme products is also minimal as recommended use levels are low, generally <0.1% (wt/wt).
What is enzyme production?
Enzymes are produced by microorganisms. These microorganisms can be modified to produce enzymes with much better yield properties and purity. Such GMMs (genetically modified micro-organisms) are however not part of the final enzyme product.
