Assessment of the Morphological, Biochemical, and Kinetic Properties for Candida rugosa Lipase Immobilized on Hydrous Niobium Oxide to Be Used in the Biodiesel Synthesis

Table 2

Thermogravimetric analysis for support, free lipase, and immobilized derivative.

Material	Temperature range (°C )	Thermal degradation temperature* (°C)	Weight loss ( % )
Pure support	30–200	53	10.5
	200–400		4.9
Free lipase	30–180	52	4.3
Immobilized lipase	30–200	54	13.6
	200–400		5.0

*Temperature at which a heated sample undergoes a major weight loss.
