Remediation of uranium contaminated soils with bicarbonate extraction and microbial U(VI) reduction
Oxford University Press (OUP) - - 1995
Elizabeth Phillips, Edward R. Landa, Derek R. Lovley
Alginate production by Azotobacter vinelandii mutants altered in poly-β-hydroxybutyrate and alginate biosynthesis
Oxford University Press (OUP) - Tập 29 - Trang 209-213 - 2002
C Peña, L Miranda, D Segura, C Núñez, G Espín, E Galindo
Mutant AT268 of Azotobacter vinelandii — showing diminished production of poly-β-hydroxybutyrate (PHB) due to a mutation in phbR (the gene coding for the transcriptional activator of the phbBAC biosynthetic operon); mutant CNT26, containing a mutation (muc26) that increases the transcription of gene algD (encoding GDP mannose dehydrogenase, the key enzyme in alginate biosynthesis); and mutant DM, ...... hiện toàn bộ
Interactions of fungi from fermented sausage with regenerated cellulose casings
Oxford University Press (OUP) - - 2011
Hassan K. Sreenath, Thomas W. Jeffries
This research examined cellulolytic effects of fungi and other microbes present in cured sausages on the strength and stability of regenerated cellulose casings (RCC) used in the sausage industry. Occasionally during the curing process, RCC would split or fail, thereby leading to loss of product. The fungus Penicillium sp. BT-F-1, which was isolated from fermented sausages, and other fungi, which ...... hiện toàn bộ
Use of an EZ-Tn5-based random mutagenesis system to create a Zymomonas mobilis with significant tolerance to heat stress and malnutrition
Oxford University Press (OUP) - Tập 40 - Trang 811-822 - 2013
Xianghui Jia, Na Wei, Tianyv Wang, Haoyong Wang
During ethanol production, the fermentation cells are always exposed to stresses like high temperature and low nutritional conditions, which affect their growth and productivity. Stress-tolerant strains with high ethanol yield are highly desirable. Therefore, a recombinant Zymomonas mobilis (Z. mobilis) designated as HYM was constructed by integrating three genes (yfdZ, metB, and Pfu-sHSP) into th...... hiện toàn bộ
Isolation and characterization of solvent-tolerant Pseudomonas putida strain T-57, and its application to biotransformation of toluene to cresol in a two-phase (organic-aqueous) system
Oxford University Press (OUP) - Tập 32 - Trang 542-547 - 2005
Irvan Faizal, Kana Dozen, Chang Soo Hong, Akio Kuroda, Noboru Takiguchi, Hisao Ohtake, Koji Takeda, Hiroshi Tsunekawa, Junichi Kato
Pseudomonas putida T-57 was isolated from an activated sludge sample after enrichment on mineral salts basal medium with toluene as a sole source of carbon. P. putida T-57 utilizes n-butanol, toluene, styrene, m-xylene, ethylbenzene, n-hexane, and propylbenzene as growth substrates. The strain was able to grow on toluene when liquid toluene was added to mineral salts basal...... hiện toàn bộ
Comparison of exopolysaccharide production by strains of Lactobacillus rhamnosus and Lactobacillus paracasei grown in chemically defined medium and milk
Oxford University Press (OUP) - Tập 24 Số 4 - Trang 251-255 - 2000
Isabelle Dupont, Denis Roy, Gisèle LaPointe
Lactic acid bacteria and yeasts in kefir grains and kefir made from them
Oxford University Press (OUP) - Tập 28 Số 1 - Trang 1-6 - 2002
Е. Симова, Дора Бешкова, Angel Angelov, Tsonka Hristozova, Ginka I. Frengova, Z.N. Spasov
Recombinant carbazole-degrading strains for enhanced petroleum processing
Oxford University Press (OUP) - Tập 30 - Trang 6-12 - 2003
Robert R. Riddle, Phillip R. Gibbs, Richard C. Willson, Michael J. Benedik
Biotechnological upgrading of fossil fuels is of increasing interest as remaining stocks of petroleum show increasing levels of contaminants such as heavy metals, sulfur and nitrogen-containing heteroaromatic compounds. Carbazole is of particular interest as a major petroleum component known to reduce refining yields through catalyst poisoning. In this study, the biotransformation of carbazole wa...... hiện toàn bộ
Bacterial exopolysaccharides produced by newly discovered bacteria belonging to the genus Halomonas, isolated from hypersaline habitats in Morocco
Oxford University Press (OUP) - Tập 24 - Trang 374-378 - 2000
S Bouchotroch, E Quesada, I Izquierdo, M Rodríguez, V Béjar
We have studied the exopolysaccharides (EPS) from a new group of moderately halophilic bacteria belonging to the genus Halomonas. The quantity of EPS produced, its chemical composition and physical properties depend greatly upon the bacterial strain. The majority of the polymers produced viscous solutions and/or emulsified different hydrocarbon compounds. The most interesting strain, S-30, produce...... hiện toàn bộ
δ-(l-α-aminoadipyl)-l-cysteinyl-d-valine synthetase (ACVS): discovery and perspectives
Oxford University Press (OUP) - Tập 44 - Trang 517-524 - 2016
Kapil Tahlan, Marcus A. Moore, Susan E. Jensen
The δ-(l-α-aminoadipyl)-l-cysteinyl-d-valine (ACV) tripeptide is the first dedicated intermediate in the biosynthetic pathway leading to the penicillin and cephalosporin classes of β-lactam natural products in bacteria and fungi. It is synthesized nonribosomally by the ACV synthetase (ACVS) enzyme, which has been purified and partially characterized from many sources. Due to its large size and ins...... hiện toàn bộ
