    摘要: A method for directed evolution in a microbe, the method comprising: introducing into a first host cell a propagation deficient phage genome and a vector comprising a target gene sequence to be mutated and a phage propagation component responsive to induce lysis of the first host cell and to provide for propagation of the phage genome; exposing the first host cell to a mutagenesis agent; inducing lysis of the first host cell and phage propagation to produce a lysate comprising phage particles comprising the target gene sequence; and infecting a second host cell with the lysate. Systems and kits for practicing the method are also disclosed.

    摘要: The invention provides engineered mitochondria and a preparation method thereof, and relates to the technical field of mitochondria. The engineered mitochondria are formed by attaching exogenous cell membranes to outer membranes of exogenous mitochondria. The preparation method comprises the following steps: S1: extracting exogenous cell membranes from cells; S2: separating and extracting exogenous mitochondria from cells or tissue; and S3: mixing the separated and extracted exogenous mitochondria with the exogenous cell membranes in a specific ratio, thereby attaching the exogenous cell membranes to the outer membranes of the exogenous mitochondria to obtain the engineered mitochondria. The invention enables the production of engineered mitochondria with enhanced biological activity, exhibiting improved therapeutic effects on mitochondrial dysfunction-related disorders.
