As microecological preparations can supplement the quantity or type of normal microorganisms that are absent in the intestinal tract, they can adjust or maintain the intestinal microecological balance, enhance immune function, and promote the digestion and absorption of nutrients to achieve disease prevention, disease treatment, an increase in the feed conversion rate and an increase in the performance of livestock and poultry production. Microecological preparation is also known as probiotics. Microecological preparation is a living microbiological preparation that can adjust the microecological balance of the body based on the theory of microecological balance, microecological imbalance, microecological nutrition and microecological prevention. Protoplast fusion, also known as cell fusion (Cheng et al., 2018), refers to the process by which the cells of the outer wall after protoplast formation and the cell wall by the release of enzymes through an external force (resultant or promotion by the melting agent) fuse and the protoplasts of two or more bacteria touch each other through membrane fusion (Hranueli et al., 1983), cytoplasmic fusion, and nuclear fusion, followed by contact and exchange between genomes, which occurs through genome genetic recombination finally, the bacterial cell walls can undergo suitable regeneration and restructuring (Ge et al., 2014 Patil et al., 2015 Zhang et al., 2006b).
Protoplast fusion allows the transfer of organelle characteristics as well as agriculturally desirable nuclear traits between sexually incompatible species (Kang et al., 2017). 238000000034 method Methods 0.One strategy for combining the desirable characteristics of a crop is interspecies hybridization by either sexual crosses or protoplast fusion.238000011069 regeneration method Methods 0.000 title abstract description 8.230000008929 regeneration Effects 0.000 title abstract description 8.241000187747 Streptomyces Species 0.000 title claims abstract description 62.210000001938 protoplasts Anatomy 0.000 title claims abstract description 65.210000004027 cells Anatomy 0.000 title claims abstract description 66.Google has not performed a legal analysis and makes no representation as to the accuracy of the date listed.)
