Molecular and physiological aspects of aflatoxin and sterigmatocystin biosynthesis by Aspergillus tamarii and A. ochraceoroseusSpringer Science and Business Media LLC - Tập 53 - Trang 605-609 - 2000
M. A. Klich, E. J. Mullaney, C. B. Daly, J. W. Cary
Until recently, only three species (Aspergillus flavus, A. parasiticus and A. nomius) have been widely recognized as producers of aflatoxin. In this study we examine aflatoxin production by two other species, A. tamarii and A. ochraceoroseus, the latter of which also produces sterigmatocystin. Toxin-producing strains of A. tamarii and A. ochraceoroseus were examined morphologically, and toxin pro...... hiện toàn bộ
The preparation and therapeutic roles of scFv-Fc antibody against Staphylococcus aureus infection to control bovine mastitisSpringer Science and Business Media LLC - Tập 103 - Trang 1703-1712 - 2019
Man Wang, Tingting Wang, Yu Guan, Fengqing Wang, Jianguo Zhu
Staphylococcus aureus–induced bovine mastitis causes significant losses to the dairy industry and available vaccines do not confer adequate protection. As a more attractive alternative, we propose the use of antibody (Ab) therapy. In our previous study, we constructed a bovine single-chain variable fragment (scFv) Ab phage display and successfully obtained scFvs that bound to S. aureus antigens wi...... hiện toàn bộ
Contrasting regulatory effects of organic acids on aerobic vinyl chloride biodegradation in etheneotrophsSpringer Science and Business Media LLC - Tập 106 - Trang 6335-6346 - 2022
Weilun Zhao, Patrick M. Richards, Timothy E. Mattes
Vinyl chloride (VC) is a common groundwater pollutant generated during anaerobic biodegradation of chlorinated solvents (e.g., trichloroethene (TCE) or tetrachloroethene (PCE)). Aerobic VC biodegradation by etheneotrophs can support anaerobic PCE and TCE bioremediation to achieve complete removal in situ. However, anaerobic bioremediation strategies necessitate biostimulation with electron donors ...... hiện toàn bộ
Immobilization of Saccharomyces uvarum cells in porous beads of polyacrylamide gel for ethanolic fermentationSpringer Science and Business Media LLC - Tập 29 - Trang 426-429 - 1988
Archana Pundle, Asmita Prabhune, Hephzibah SivaRaman
A procedure which does not involve the use of an immiscible organic solvent phase is described for the entrapment of yeast cells in porous beads of polyacrylamide gel. The cells are rapidly dispersed at 4° C in an aqueous solution containing sodium alginate and acrylamide-N,N′methylene-bis-acrylamide monomer, and the suspension is immediately dropped into a solution of calcium formate to give calc...... hiện toàn bộ
Studies on the thermostability of the α-amylase of Bacillus caldoveloxSpringer Science and Business Media LLC - - 1991
Francis Bealin-Kelly, Catherine T. Kelly, William M. Fogarty
Molecular mechanisms of thermoinactivation of the thermostable α-amylase of Bacillus caldovelox were examined. Monomolecular conformational processes were found to be the major causes of thermoinactivation at both pH 4.5 and 8.0. The enzyme possessed considerable additional thermostability at pH 8.0, with half-lives of 0.75 and 7.0 min at 90° C and pH 4.5 and 8.0, respectively. The amino acid comp...... hiện toàn bộ
