Disclosed is a coating composition for preventing odor. The coating composition may include one or more types of odorless microorganisms selected from the group consisting ofandor a culture solution thereof. Further provided is a method for preventing odor, and the method may include applying the coating composition for preventing odor. When a biofilm is formed from the microorganisms in the coating composition by coating an object on which an odor-causing microorganism can live, the inflow and the inhabitation of external microorganisms generating odor may be significantly blocked, thereby enabling odor to be effectively prevented.

Composition for preventing odor, containing odorless microorganisms

The present invention relates to an apparatus and a method that can accelerate reproduction of odor from an air-conditioner by segmenting microorganisms, a temperature/humidity condition and nutrients for metabolism of the microorganisms as conditions for reproducing the odor from the air-conditioner and setting the segmented microorganisms, a temperature/humidity condition and nutrients for metabolism of the microorganisms according to an accelerated condition thereof.

A catalytic converter of an internal combustion engine may include: at least one inlet channel having an end through which an exhaust gas is flowed into and the other end which is blocked; at least one outlet channel having an end which is blocked and the other end through which the exhaust gas is discharged; and a wall defining a boundary between neighboring inlet channel and outlet channel, and adapted to flow the exhaust gas from the inlet channel to the outlet channel, wherein the wall includes a single-layered portion formed at an end portion and having a three-way catalyst layer, and a multi-layered portion being the portion other than the single-layered portion and having a three-way catalyst layer, a hydrocarbon trap layer and an insulating layer. An apparatus of purifying an exhaust gas is also provided.
