Utilization of Natural Phenolic Compounds by Microorganisms | Original Article

ABSTRACT:

Phenolics and removed phenolic mixtures of Scots pine (Pinus sylvestris) and Norway tidy (Picea abies) show antibacterial action against a few microorganisms. Most of phenolic compounds are stilbenes, flavonoids, proanthocyanidins, phenolic acids, and lignans that are biosynthesized in the wood through the phenylpropanoid pathway. In Scots pine (P. sylvestris), the most plentiful phenolic and antibacterial mixtures are pinosylvin-type stilbenes and flavonol-and dihydroflavonol-type flavonoids, for example, kaempferol, quercetin, and taxifolin and their subsidiaries. In Norway tidy (P. abies) then again, the fundamental stilbene is resveratrol and the significant flavonoids are quercetin and myricetin. By and large, when the outcomes from the writing with respect to the exercises of flavonoid glycosides and their aglycones against a sum of 21 microorganisms are summed up, it was discovered that phenolic glycosides are less dynamic than the comparing aglycones, albeit various special cases are likewise known. The aglycones in plants react to different sorts of biotic pressure. Synergistic impacts among aglycones and their glycosides have been noticed. Least hindrance groupings of under 10 mg L−1 against microbes have been accounted for gallic corrosive, apigenin, and a few methylated and acylated flavonols present in these modernly significant trees. As a rule, the phenolic compounds are more dynamic against Gram-positive microorganisms, however apigenin is accounted for to show solid movement against Gram-negative microscopic organisms. The current survey records a portion of the biosynthesis pathways for the antibacterial phenolic metabolites found in Scots pine (P. sylvestris) and Norway tidy (P. abies). The antimicrobial action of the mixtures is gathered and contrasted with assemble data about the best auxiliary metabolites.
