Beta-amylases from various fungal strains. A review.
Ray RR. Ray RR. Acta Microbiol Immunol Hung. 2004;51(1-2):85-95. doi: 10.1556/AMicr.51.2004.1-2.6. Acta Microbiol Immunol Hung. 2004. PMID: 15362290 Review.
Among the few available report on beta-amylase producing fungal strains, many showed a preference for a cultivation temperature of 28 degrees C, acidic pH and soluble starch as an inducer of enzyme synthesis. ...

Biochemical approaches of increasing thermostability of beta-amylase from Bacillus megaterium B6.
Ray RR, Jana SC, Nanda G. Ray RR, et al. FEBS Lett. 1994 Dec 12;356(1):30-2. doi: 10.1016/0014-5793(94)01227-x. FEBS Lett. 1994. PMID: 7988714 Free article.
Studies on the irreversible thermoinactivation of beta-amylase from Bacillus megaterium B6 exposed to 60 degrees C revealed that the deactivation mechanism probably results from the oxidation of thiols present at the active site of the enzyme. ...

Purification and characterization of extracellular beta-amylase of Bacillus megaterium B(6).
Ray RR. Ray RR. Acta Microbiol Immunol Hung. 2000;47(1):29-40. Acta Microbiol Immunol Hung. 2000. PMID: 10735188
The pH and temperature optima of the purified beta-amylase were at 6.9 and 60 degrees C, respectively. Mn2+ and exogenous thiols were found to play a remarkable role in reactivation of thermally and chemically denatured enzyme. ...

Production and characterization of xylanase from a beta-amylolytic strain of Bacillus megaterium.
Ray RR, Nanda G. Ray RR, et al. Microbios. 1997;90(362):7-16. Microbios. 1997. PMID: 9301068
The ultrafiltered xylanase showed temperature and pH optima at 85 degrees C and 7.5, respectively. The enzyme was stable at 50 degrees C for 20 min and in the pH range of 7-9. ...
