Kinetics of Manganese Lipoxygenase with a Catalytic …
Manganese lipoxygenase was isolated from the take-all fungus, Gaeumannomyces graminis, and the oxygenation mechanism was investigated. A kinetic isotope effect,k H/k D = 21–24, was observed with [U-2H]linoleic acid as a substrate. The relative biosynthesis of (11S)-hydroperoxylinoleate (11S-HPODE) and (13R) …

Dosing Manganese(II) chloride tetrahydrate | REEF2REEF …
Note especially the last sentence. Manganese (Mn) is a transition metal which can exist in a range of oxidation states, +2, +3, +4, +6 and +7. The divalent form, Mn (II), predominates in most waters at pH 4-7. If the pH and redox potential of the water are increased (by the addition of lime and chlorine) then Mn (II) may be oxidised to Mn (IV).

Role of Manganese in Plant Culture | PRO-MIX Greenhouse …
Correcting Manganese Deficiency. Manganese and iron are closely related, so manganese competes with iron and, to a lesser extent, with zinc, copper, magnesium and calcium for uptake by the plant. Maintain the manganese to iron ratio at about 1:2 to 1:4. If the manganese ratio is lower, then it can induce a manganese deficiency.

calcium, manganese and copper are widely used to provide essential elements in plant growth . They are primarily used for soil application although low rates are used for foliar application, care must be taken to avoid foliar burn. The pH usually runs between 2.5 and 4.0. The analysis varies and pH tends to go lower over time.
