The contribution of different α-amylase isoenzymes of the commodity grain spring wheat in the formation of falling number values
Springer Science and Business Media LLC - Tập 50 - Trang 531-537 - 2014
N. S. Mamytova, V. A. Kuzovlev, A. A. Khakimzhanov, O. V. Fursov
The participation of various isoenzymes of α-amylase in the formation of falling number values of the commodity grain of wheat grown in the Republic of Kazakhstan was investigated. It was found that active isoenzymes α-AMY1 and α-AMY2 of the embryonic shield were present in the grain with an index over 200. A significant decrease in the falling number depended mainly on the synthesis of α-AMY1 and...... hiện toàn bộ

Sản xuất hydrolase bởi vi khuẩn lactic và bifidobacteria và khả năng kháng kháng sinh của chúng Dịch bởi AI
Springer Science and Business Media LLC - Tập 43 - Trang 164-172 - 2007
G. I. Novik, N. I. Astapovich, N. E. Ryabaya
Nghiên cứu đã chỉ ra rằng bifidobacteria và vi khuẩn acid lactic B. adolescentis và Lactobacillus sp. tổng hợp các enzyme ngoại bào có khả năng cắt đứt các liên kết glycoside trong các phân tử dextran, axit pectic và tinh bột hòa tan. Sản xuất tối đa enzyme β-galactosidase ngoại bào bởi B. adolescentis 91-BIM và 94-BIM lần lượt đạt 0,08 và 0,03 U/mg mỗi giờ trong giai đoạn tăng trưởng bùng nổ sau ...... hiện toàn bộ

Inducible specific lux-biosensors for the detection of antibiotics: Construction and main parameters
Springer Science and Business Media LLC - Tập 50 - Trang 98-103 - 2013
V. Yu. Kotova, K. V. Ryzhenkova, I. V. Manukhov, G. B. Zavilgelsky
Based on Escherichia coli, highly sensitive specific lux-biosensors for the detection of tetracycline and β-lactam antibiotics, quinolones, and aminoglycosides have been obtained. To make biosensors, bacteria were used that contained hybrid plasmids pTetA’::lux, pAmpC’::lux, pColD’::lux, and pIbpA’::lux, in which transcription of the reporter Photorhabdus luminescens luxCDABE genes occurred from t...... hiện toàn bộ
The effect of Azotobacter vinelandii on plant seed germination and adhesion of these bacteria to cucumber roots
Springer Science and Business Media LLC - Tập 44 - Trang 400-404 - 2008
I. K. Kurdish, Z. T. Bega, A. S. Gordienko, D. I. Dyrenko
Bacterization of seeds of several plant species with Azotobacter vinelandii suspension stimulates their germination to different degrees. This demonstrates that seeds of different species display different sensitivity to the biologically active substances accumulating in the culture liquid of these bacteria. The adhesion patterns of these bacteria to cucumber roots were studied. The maximal number...... hiện toàn bộ
Alternative Synthesis of Cefamandole with Biocatalytic Acylation Catalyzed by Immobilized Cephalosporin-Acid Synthetase
Springer Science and Business Media LLC - Tập 58 - Trang 251-260 - 2022
A. V. Sklyarenko, I. A. Groshkova, I. N. Krestyanova, S. V. Yarotsky
The processes of the biocatalytic acylation of 1-methyl-5-mercapto-1,2,3,4-tetrazolil-7-amino-cephalosporanic acid (7-TMCA) and 7-aminocephalosporanic acid (7-ACA) by methyl ester of mandelic acid (MEMA) were optimized with an immobilized cephalosporin-acid synthetase as the biocatalyst. Under optimized conditions in water-organic medium containing 43% (vol/vol) of ethylene glycol at 30°С with a s...... hiện toàn bộ

Influence of polycations on antibacterial activity of lysostaphin
Springer Science and Business Media LLC - Tập 51 - Trang 683-687 - 2015
S. N. Kulikov, R. Z. Khairullin, V. P. Varlamov
The synergistic antibacterial activity of lysostaphin and polycations of different chemical structures against Staphylococcus aureus has been shown. Polycations improved the lytic activity of lysostaphin against the peptidoglycan of staphylococci. It is proposed that this resulted in decreased binding of positively charged lysostaphin with S. aureus cell-wall teichoic acids. These data provide an ...... hiện toàn bộ
The antioxidant characteristics of medicinal plant extracts from Western Siberia
Springer Science and Business Media LLC - Tập 45 - Trang 638-641 - 2009
G. V. Smirnova, G. I. Vysochina, N. G. Muzyka, Z. Yu. Samoilova, T. A. Kukushkina, O. N. Oktyabr’ski
An antioxidant activity of the water-alcohol extracts of leaves of ten herbs from Western Siberia was studied. In vivo the capability of extracts to protect cells of Escherichia coli against the bacteriostatic action of H 2O2 and the influence of the extracts on the expression of the antioxidant gene katG coding catalase-hydroperoxidase I were investigated. In vitro the radical-binding activity wi...... hiện toàn bộ
