Construction method of phaeodactylum tricornutum calreticulin gene overexpression mutant strain

Номер: CN116218681A
Принадлежит:

The invention provides a method for constructing a phaeodactylum tricornutum calreticulin gene overexpression mutant strain, which comprises the following specific steps: 1) constructing an overexpression plasmid: obtaining a phaeodactylum tricornutum calreticulin fragment, a fluorescence marker and a plasmid skeleton, and connecting through a recombinant cloning reagent; 2) transformation verification: transforming the constructed overexpression plasmids into competent cells, and detecting and verifying the correctness of the recombinant sequence of the constructed overexpression plasmids after amplification culture; and 3) constructing a mutant strain: transforming the overexpression plasmid which is verified to be correct into phaeodactylum tricornutum. The constructed phaeodactylum tricornutum calreticulin gene overexpression mutant strain can cope with a stress environment, and especially can enable phaeodactylum tricornutum to keep a relatively good growth rate under a nitrogen limiting ...

Plant arrangement structure applied to four pipelines of single-shaft gas turbine

Номер: CN116498408A
Принадлежит:

The invention relates to the field of gas-steam combined cycle generator sets, and discloses a plant layout structure applied to four pipelines of a single-shaft gas turbine. The device comprises a base, a lubricating oil tank, a single-shaft gas-steam combined cycle generator set, a main steam pipeline, a high-temperature reheating steam pipeline, a low-temperature reheating pipeline, a low-pressure steam pipeline, a high-pressure main steam valve, a low-pressure main steam valve, a reheating main steam valve and a lubricating oil pipeline. According to the embodiment of the invention, the arrangement lengths of the main steam pipeline, the high-temperature reheating steam pipeline, the low-temperature reheating pipeline and the low-pressure steam pipeline can be reduced, the number of elbows is reduced, the pressure drop is small, the system efficiency is improved, and the construction cost is saved. Besides, the oil pipeline is fully isolated from the main steam pipeline, the high-temperature ...
