Differential Phenolic Accumulation in Two Hypericum Species in Response to Inoculation with Diploceras hypericinum and Pseudomonas putida
fungal pathogen Hypericum perforatum Hypericum triquetrifolium
2015/3/11
The genus Hypericum L. (St. John’s-wort, Hypericaceae) has received scientific interest in recent years, because it is a
source of a variety of bioactive compounds including the phenolics. We determ...
研究了温度、转速、pH、接种量、碳源和亚硝酸盐氮浓度对耐冷反硝化细菌Pseudomonas putida Y-12去除亚硝酸盐氮和总氮的影响,在此基础上,初步考察了反硝化脱氮产物中温室气体(CO2和N2O)的含量,探索了对富营养化景观水体中亚硝酸盐氮和总氮的去除能力.结果表明:Y-12菌株去除亚硝酸盐氮和总氮的最佳碳源为柠檬酸钠,在15℃和pH为7.2条件下,该菌以柠檬酸钠为唯一碳源对亚硝酸盐氮和...
Biological Control of Rhizoctonia damping-off of Cucumber by a Transformed Pseudomonas putida Strain Expressing a Chitinase from a Marine Bacterium
biological control agent fluorescent pseudomonads rhizosphere
2011/2/24
To construct an effective biological control agent for plant root diseases, we isolated Pseudomonas putida strains from the rhizospheres of cucumber plants and used them as hosts of an expression vect...

Production of D-p-Hydroxyphenylglycine From DL-5-p-Hydroxyphenyl Hydantoin by Immobilized Pseudomonas Putida Cells in a Hollow Fiber Memgrane Bioreactor.
以苯酚-四氯苯酚共代谢体系为对象，研究了中空纤维聚砜膜作为细菌固定化材料对该共代谢过程的强化作用.结果表明，该膜具有内、中、外3层的结构，Pseudomonas putida菌可被固定在膜的表面和中间层；固定化后，细菌对高浓度有毒底物的忍受限度增强，从而得以持续生长，并在29 h内将600 mg/L和120 mg/L的苯酚和四氯苯酚完全降解.在膜的制作过程中添加了一定量的活性炭后，发现膜对苯酚和四...
Determination of Structure-Toxicity Relationship of Amphiprotic Compounds by Means of the Inhibition of the Dehydrogenase Activity of Pseudomonas Putida
Determination Structure-Toxicity Relationship of Amphiprotic Compounds Means of the Inhibition the Dehydrogenase Activity Pseudomonas Putida
2010/6/30
Aliphatic and aromatic alcohols are amphiprotic compounds which have both polar and nonpolar parts in their structure. These compounds were studied with respect to the nonreactive toxic effects on th...
Involvement of genes of the two-step protein secretion pathway in the transport of the manganese-oxidizing factor across the outer membrane of Pseudomonas putida strain GB-1
Involvement of genes two-step protein secretion pathway transport manganese-oxidizing factor Pseudomonas putida strain GB-1
2012/4/1
Microorganisms can accelerate the rate of Mn21 oxidation by up to five orders of mag-nitude compared to abiotic Mn21 oxidation. Mn21 oxidation in Pseudomonas putida strain GB-1 involves an enzyme inco...
