Abstract: A method of decoloring an ionic liquid includes preparing a discolored ionic liquid, and decoloring the discolored ionic liquid through irradiation with UV rays. An ionic liquid that is discolored due to heat treatment upon purification is decolored and can thus be reused. The method of decoloring the ionic liquid is effective because an ionic liquid, which is discolored due to heat treatment upon purification, can be decolored in a simple manner and also because an ionic liquid, which is discolored and is thus difficult to apply to the purification of an organic material, can be decolored in a simple manner, and can thus be reused in the form of a high-purity ionic liquid.

Abstract: The present invention relates to a novel analogue antibiotic peptide derived from a CM-MA peptide and a use thereof. Specifically, the novel antibiotic peptides represented by SEQ. ID. NO: 2 to SEQ. ID. NO: 7 (CAM 1 to CMA 6) were synthesized by using a CM-MA antibiotic peptide, in which amphiphilic cecropin A (CA) and magainin 2 (MA) are conjugated, as a template. The synthesized antibiotic peptide exhibits antibiotic activity on gram-positive bacteria and gram-negative bacteria and low cytotoxicity on human red blood cells and human normal cell lines (HaCaT), and thus the antibiotic peptide of the present invention can be favorably used as an active ingredient of an antibiotic agent, a cosmetic composition, a food additive, a feed additive, and a biological pesticide.
