S u rn m a r yImmobilization of amyloglucosidase (EC 3.2.1.3) from Endomycopsis bisporu and Aspergillus niger was followed with carriers containing epoxide, aldehyde, and primary amino groups. Determinations of stability of bound enzyme showed that the most active and stable preparations were obtained by application of the carrier with amino groups activated with glutaraldehyde (activity half-life 96.6 days). Optimum pH and and temperature were found for cleavage of starch solution and K,(app) and V,,,(app) values were determined for all prepared samples.
We have shown here how to find an integral representation for the solution of the Euclidean equations of motion of a quantum mechanical point particle in a general potential and in the presence of a four-Fermi term. The classical action in this theory depends explicitly on a set of four fermionic collective coordinates. The corrections to the classical action due to the presence of fermions are of topological nature in the sense that they depend only on the values of the fields at the boundary points τ → ±∞. As an application, the quantum mechanical sine-Gordon model with a four-Fermi term is solved explicitly and the corrections to the classical action are computed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
