  • Patent number: 10383353
    Abstract: A vegetable washing method capable of separating and splitting impurities and a machine therefor. The method comprises putting fruit and vegetable into a washing basket, then driving the wash basket to rotate by an electric motor so as to force water flow to circulate repeatedly, as a result separating the impurities and the vegetable. The method has the following three technical features of A, B and C, or at least has one of them. A. using a method for preventing the impurities thrown outside the washing basket together with the water from circularly falling into the basket again together with the water to gradually purify the vegetable in the basket; B. using a vortex center draining method to discharge the sewage and impurities; C. using a method for making the vegetable in the washing basket periodically centripetal and centrifugal motion to flip and turn the placement angle of the vegetable in the basket.

  • Patent number: 10378019
    Abstract: Methods of pre-methylation of foreign DNA to improve genetic transformation in cyanobacterium. Two Type II methyltransferase-encoding genes, i.e., M (sll0729) and C (slr0214), were cloned from the chromosome of Synechocystis sp. PCC 6803 (hereafter Synechocystis 6803) and expressed in E. coli that harbors the integrative plasmid pBS-SPtK or pJU105. After pre-methylation in E. coli, the integrative plasmids were extracted and used for transformation of Synechocystis 6803. The results showed that expression of slr0214 in the integrative-plasmid-harboring E. coli cells before DNA preparation resulted in orders of magnitude higher efficiency in the following integrative transformation of Synechocystis 6803.

    Abstract: Construction and expression of synthetic pathways to produce (S) or (R)-3-hydroxybutyrate (3HB) as enantiomerically-pure products by genetically engineering cyanobacterium Synechocystis sp. PCC 6803. Under optimized growth conditions, the pathway employing phaA and phaB from R. eutropha was the most effective, producing up to 533.4±5.5 mg/l (R)-3HB after 21 days photosynthetic cultivation. For the first time, the feasibility and high efficiency of producing 3HB using solar energy and CO2 as sole energy and carbon sources by engineered cyanobacteria is demonstrated.
