perlite, also called pearlstone, a natural glass with concentric cracks such that the rock breaks into small pearl-like bodies. It is formed by the rapid cooling of viscous lava or magma. Perlite has a waxy to pearly lustre and is commonly gray or greenish but may be brown, blue, or red.

β-Glucosidases function in glycolipid and exogenous glycoside metabolism in animals, defense, cell wall lignification, cell wall β-glucan turnover, phytohormone activation, and release of aromatic compounds in plants, and biomass conversion in microorganisms.

β-xylosidase is an exoglycosidase with the ability to degrade the non-reducing ends of xylooligosaccharides into xylose, which is one kind of hemicellulolytic enzyme. Compared with the other β-xylosidases, Xln-DT possessed higher efficiency in xylobiose hydrolysis.

Ethanethiol, commonly known as ethyl mercaptan, is an organosulfur compound with the formula CH3CH2SH. is a colorless liquid with a distinct odor. Abbreviated EtSH, it consists of an ethyl group (Et), CH3CH2, attached to a thiol group, SH. Its structure parallels that of ethanol, but with sulfur in

Chlorotoluene is a group of three isomeric chemical compounds. They (ortho-chlorotoluene, meta-chlorotoluene, and para-chlorotoluene) consist of a disubstituted benzene ring with one chlorine atom and one methyl group.

Didecyldimethylammonium chloride (DDAC) is a quaternary ammonium compound used as antiseptic/disinfectant. It causes the disruption of intermolecular interactions and the dissociation of lipid bilayers.

Hydrated silica is an odourless white powder derived from silica (silicon dioxide), an abundant compound found in around the world in quartz, sand and obsidian. It has mild abrasive properties, and can be used in toothpaste to assist with whitening and the removal of plaque.

Polysulfone, any of a class of resinous organic chemical compounds belonging to the family of polymers in which the main structural chain most commonly consists of benzene rings linked together by sulfonyl (―SO2―), ether (―O―), and isopropylidene (―C(CH3)2―) groups.

Hydrogen cyanamide is applied as a single airblast or backpack spray to the plant buds approximately 30 days before bud break to synchronize blossoming andlor produce a more uniform bud break in plants that have received less than their full chill hour requirement.

Perfluoroethers are a class of organofluorine compound containing one or more ether functional group. In general these compounds are structurally analogous to the related hydrocarbon ethers, except for the distinctive properties of fluorocarbons.
