β-fruc·to·fu·ran·o·sid·ase

(fruk'tō-fūr'ă-nō'sid-ās),
β-h-fructosidase; an enzyme hydrolyzing β-d-fructofuranosides and releasing free d-fructose; if the substrate is sucrose, the product is d-glucose plus d-fructose (invert sugar); invert sugar is more easily digestible than sucrose.

(ĭn-vûr′tās′, ĭn′vər-tās′, -tāz′)
n.
An enzyme that catalyzes the hydrolysis of sucrose into glucose and fructose. Also called saccharase, sucrase.

The activities of enzyme such as trehalase, amylase and invertase which are primarily concerned with energy production were decreased which was probably due to either decreased synthesis or enzyme inhibition.

Invertase, the enzyme that catalyzes the hydrolysis of sucrose to D-glucose and D-fructose, sugars that are important sources of energy for microorganisms (Jin et al., 2009); xylanase, the enzyme that hydrolyzes xylan to release xylobiose and xylose; and urease activity all diminished in soils fertilized with N[P.sub.2][O.sub.5]K and copper sulfate ([Cu.sub.2]S[O.sub.4]) (Butt et al., 2008).
