Ytterbium has few industrial uses and no essential biological role for ytterbium is known. In the absence of Ca2+, Yb3+ restored 93% of Bacillus subtilis α-amylase activity (Smolka et al, 1971). Biosorption of Yb3+ by Pseudomonas aeruginosa (Texier et al, 2002) and Mycobacterium smegmatis (Andres et al, 1993) has been investigated.
