Extracellular secretion of levansucrase from Zymomonas mobilis in Escherichia coli.
For example, Bacillus can produce some useful enzymes ([alpha]-amylase, arabinase, cellulase, dextranase, levansucrase, maltase, alkaline protease, neutral protease and [beta]-glucanase) (Priest, 1977; Hentges, 1992) that were found to improve feed efficiency and weight gain of weaned piglets (Zani et al., 1998).
Further, introduction of the bacterial levansucrase, which synthesizes fructan, in tobacco (Nicotiana tabacum L.) renders the transgenic plant more tolerant to drought (Pilon-Smits et al., 1995).
