Method for promoting accumulation of oil in microalgae and keeping high biomass of microalgae

ActiveCN107384802AIncrease biomassIncrease contentUnicellular algaeMicroorganism based processesPlant hormoneBiodiesel
The invention discloses a method for promoting the accumulation of oil in microalgae and keeping the high biomass of the microalgae. The method is concretely characterized in that enrichment-cultured microalgae are cultured in a nitrogen-deficient medium containing a plant hormone. The plant hormone indoleacetic acid is added to the nitrogen-deficient medium for the first time in order to stimulate the accumulation of oil in microalgae and keep the high biomass of the microalgae, so the microalgae can still keep a high biomass under a nitrogen deficiency condition. Test proves that the method makes the oil content of chlorella higher than the oil content of the chlorella cultured in a nitrogen-free medium free from the plant hormone, so the plant hormone can be used as a good means for stimulating the microalgae to produce oil. The method has the advantages of simplicity in operation, short time, high efficiency, easiness in realization, effective increase of the biomass concentration of the microalgae under a nitrogen-deficient culture condition, and good applicability, and provides an effective technical scheme for microalgae to produce biodiesel or develop other biomass energy sources.

ActiveCN106404972ASimple methodDetermination is accurate and reliableComponent separationGas phasePlant growth
The invention relates to a determination method for six residual plant-growth regulators in a bean sprout, especially to a method for simultaneous determination of six residual plant-growth regulators in the bean sprout by using gas chromatography-tandem mass spectrometry. Six plant-growth regulators involved in the invention are composed of 4-chlorophenoxyacetic acid, 2,4-dichlorophenoxyacetic acid, naphthylacetic acid, indoleacetic acid, 2,4-D-butyl ester and indolebutyric acid. The method comprises the following steps: 1) sample treatment; 2) determination, wherein gas chromatography-tandem mass spectrometry is employed; 3) drafting of a standard curve; 4) blank test; and 5) result calculation and description. The determination method employs gas chromatography-tandem mass spectrometry for simultaneous determination of the six residual plant-growth regulators in bean sprout; and the method is simple, convenient, rapid, accurate and reliable, and the lower determination limit, recovery rate and precision of the method all accord with requirements.

Pseudomonas vranovensis with phosphorus solubilizing capability and application thereof

InactiveCN104371946AGuaranteed stabilityStable genetic traitsBiocidePlant growth regulatorsBacterial strainMicrobiological culture
The invention discloses pseudomonas vranovensis with phosphorus solubilizing capability, a preparation method and application thereof. Through an ultraviolet-ray plasma composite mutation technology for multiple composite mutation, a bacterial strain ZSW-3-5-1a with high solubilizing efficiency on phosphorus and good stability is selected and bred, has the classification name of pseudomonas vranovensis, is preserved in China General Microbiological Culture Collection Center, and the preservation number is CGMCC No. 8750. The bacterial strain has efficient solubilizing capability on calcium phosphate and calcium phytate, and also is capable of generating a certain amount of indoleacetic acid. By using a liquid containing the bacterium or a solid inocula to inoculate corn, soybean, mustard and other crops, utilization rate on phosphorus in soil is improved and crop output is improved.

Alfalfa growthpromoting rhizobacteria MJM-11 and application thereof

ActiveCN102796684AGood regulationImprove stress resistancePlant growth regulatorsBiocideRhizobacteriaGrowth promoting
The invention discloses an alfalfa growth-promoting rhizobacteria MJM-11 and application thereof. An Enterobacter ludwigii strain MJM-11 has a preservation number of CGMCC No.6295. The Enterobacter ludwigii strain MJM-11 can be applied in at least one of the following four ways: 1, preparation of an ACC (1-aminocyclo propane-1-carboxylate) ammonialyase; 2, preparation of indoleacetic acid; 3, preparation of siderophores; and 4, promotion of the growth of plants under the saline-alkali stress. Experiments prove that the alfalfa growth-promoting rhizobacteria MJM-11 which is obtained through separation can be used for synthesizing the ACC ammonialyase and the IAA (Indole Acetic Acid) siderophores and is capable of effectively promoting the alimentation of plants in a saline-alkali stress environment, regulating the growth of plants and enhancing the stress resistance capacity of plants in adverse conditions.
