Abstract
Is Laccase Enzyme an Answer for Sustainable Thatch Management in Turfgrass Systems: A Review
Highlights
Lignin, a major component of plant cell wall, acts as a protective matrix and limits microbial degradation of cellulose and hemi-celluloses which are readily degraded by microbes [1]
Certain white-rot fungi produce extra-cellular enzymes known as lignolytic enzymes which are capable of lignin degradation [8]
This article reviewed complex structure of lignin, structure and unique oxidation mechanism of laccase enzyme that makes it suitable to be used in turfgrass systems, and developmental progress of laccase as a technique to manage thatch layer
Summary
A major component of plant cell wall, acts as a protective matrix and limits microbial degradation of cellulose and hemi-celluloses which are readily degraded by microbes [1]. Excessive thatch layer accumulation leads to physical conditions in thatch which are detrimental to turfgrass [6] Cultural management practices such as core aeration, vertical mowing, and grooming are destructive in nature and adversely impact turf quality. Several non-destructive studies in the past utilized glucose, cellulase, mixture of amino acids, and microbial inocula to enhance organic matter decomposition in thatch layer. These studies proved futile as they were targeting decomposition of cellulose and hemi-cellulosic components instead of lignin [1,7]. This article reviewed complex structure of lignin, structure and unique oxidation mechanism of laccase enzyme that makes it suitable to be used in turfgrass systems, and developmental progress of laccase as a technique to manage thatch layer
