Pectinase enzymes used today are naturally produced by fungi and yeasts (50%), insects, bacteria and microbes (35%) and various plants (15%), [4] but cannot be synthesized by animal or human cells. [5] In plants, pectinase enzymes hydrolyze pectin that is found in the cell wall, allowing for new growth and changes to be made.
Environmental conditions such as soil pH, [18] soil temperature, [19] moisture content, [20] and plant litter type and quality [21] have the potential to alter exoenzyme expression and activity. Variations in seasonal temperatures can shift metabolic needs of microorganisms in synchrony with shifts in plant nutrient requirements. [ 22 ]
Pectin lyase is a component that is found in plant cell walls. This enzyme creates unsaturated products by breaking the glycosidic bonds that are inside. Pectin lyase is critical for several biological processes, such as the maturation of fruits and reshaping of plant cell walls.
A water-purifying plant (Iris pseudacorus) in growth after winter (leaves die at that time of year) The choice of plants in engineered wet-lands or managed lagoons is dependent on the purification requirements of the system and this may involve plantings of varying plant species at a range of depths to achieve the required goal.
Pectic acid, also known as polygalacturonic acid, is a water-soluble, transparent gelatinous acid existing in over-ripe fruit and some vegetables. It is a product of pectin degradation in plants, and is produced via the interaction between pectinase and pectin (the latter being common in the wine-making industry.) In the early stage of ...
Phytase is used as an animal feed supplement – often in poultry and swine – to enhance the nutritive value of plant material by liberation of inorganic phosphate from phytic acid (myo-inositol hexakisphosphate). Phytase can be purified from transgenic microbes and has been produced recently in transgenic canola, alfalfa and rice plants. [34]
Tentoxin has also been used in recent research to eliminate the PPO activity from seedlings of higher plants. [19] Tropolone is a grape polyphenol oxidase inhibitor . [ 20 ] Another inhibitor of this enzyme is potassium metabisulfite . [ 21 ]
Water-use efficiency is also a much studied trait in Plant ecology, where it has been used already in the early 20th century to study the ecological requirements of Herbaceous plants [12] or forest trees, [13] and is still used today, for example related to a drought-induced limitation of tree growth [14]
