摘要： The present invention relates to a method for producing a recombinant polynucleotides comprising the steps of generating a pool of unidirectional single-stranded polynucleotide fragments from two or more homologous double-stranded polynucleotides, conducting a polymerization process comprising multi-cyclic extension reactions using the unidirectional single-stranded polynucleotide fragments as templates and specific oligonucleotides as primers to obtain recombinant polynucleotides, and conducting a polymerase chain reaction using at least one primer to amplify the recombinant polynucleotides; and a method for constructing a recombinant DNA library comprising the steps of inserting the recombinant polynucleotide prepared by the above method into a vector and transforming an expression cell with said vector containing the recombinant polynucleotide to obtain a plurality of mutant clones. The method of the present invention can be used for in vitro recombination of homologous polynucleotides and the directed molecular evolution.

摘要： A method of preparing a volatile fatty acids (VFAs) is provided. More particularly, the method includes chemically or biologically pretreating a residue of algae to obtain an extract of the algae residue, filtering the extract of the algae residue and anaerobically fermenting the filtrate. The method of preparing VFAs can be used regardless of the kinds of algae, a process of producing VFAs can be simplified since there is no need to develop an enzyme for anaerobic fermentation, and a yield of VFAs can be increased since the VFAs can be produced from different kinds of organic components such as proteins or fats in addition to carbohydrates. Accordingly, the method can be useful in producing VFAs in an economical and efficient manner.
