The present invention relates to: a method for screening for an antimicrobial agent capable of controlling microorganisms causing offensive odor in an air conditioning apparatus; and a method for removing offensive odor in the air conditioning apparatus. The microorganism causing offensive odor in the air conditioning apparatus, of the present invention, can be used in the development of a novel antimicrobial agent or in the development of an aromatic for blocking offensive odor by establishing the chemical properties of metabolites of the microorganisms. In addition, there are various industrial applications such as a use for fundamentally removing the cause of offensive odor by creating, in advance, an environment in which the microorganisms cannot live in the air conditioning apparatus.
The present invention relates to a composition for preventing odor, containing one or more types of odorless microorganisms selected from the group consisting of Caulobacter vibrioides, Bradyrhizobium diazoefficiens, Bradyrhizobium daqingense and Methylobacterium brachiatum or a culture solution thereof. In addition, the present invention relates to a method for preventing odor, comprising a step of applying the composition for preventing odor. When a biofilm is formed by applying the composition for preventing odor, of the present invention, to an object on which an odor-causing microorganism can live, the inflow and the inhabitation of external microorganisms, which can cause odor, are significantly blocked, thereby enabling odor to be effectively prevented.
The present invention relates to a sound-absorbing/insulating material having improved heat resistance and moldability and a method for producing same and, more specifically, to a sound-absorbing/insulating material and a method for producing same, the sound-absorbing/insulating material having a structure in which a heat-resistant material, which is produced by impregnating a non-woven fabric comprising heat-resistant fibers with a binder, is stacked as a surface layer on one surface of a base layer made of a conventional sound-absorbing/insulating material.

The present invention relates to a sound-absorbing/insulating material having an excellent exterior and moldability and a method for producing same and, more specifically, to a sound-absorbing/insulating material and a method for producing same, the sound-absorbing/insulating material comprising: an inner sound-absorbing/insulating layer (1), which comprises a first non-woven fabric comprising heat-resistant fibers as main constituents and a binder evenly distributed inside the first non-woven fabric in the form of maintaining the three-dimensional shape of the inside of the first non-woven fabric; and an outer sound-absorbing/insulating layer (2', 2"), which comprises a second non-woven fabric comprising heat-resistant fibers as main constituents, the sound-absorbing/insulating material having a structure in which the outer sound-absorbing/insulating layer is stacked on one side or both sides of the inner sound-absorbing/insulating layer. The sound-absorbing/insulating material according to the present invention has excellent sound-absorbing properties, flame retardancy, heat resistance, heat-insulating properties, and high-temperature moldability and, in particular, by having the outer sound-absorbing/insulating layer(s), eliminates all risk of the binder being smeared on a mold during molding and consequently damaging the exterior of a molded product.

COMPOSITION FOR PREVENTING ODORS COMPRISING ODORLESS METHYLOBACTERIUM SPP
The present invention relates to a composition for preventing odors, and to a method for preventing odors which includes coating the composition on an evaporator core. The composition for preventing odors includes microorganisms including Methylobacterium or a culture thereof, and a medium component, wherein the Methylobacterium is one or more of Methylobacterium komagatae, Methylocaterium aquaticum, Methylobacterium brachiatum and Methylobacterium platani. By coating and proliferating the microorganisms contained in the composition on the evaporator core, a biofilm rnay be formed whereby odors may effectively be prevented by reducing inflow and inhabitation of outside microorganisms that generate offensive odors.

Abstract
The present invention relates to a sound-absorbing material having excellent sound absorption properties and to a method for manufacturing same; and, more particularly, to a sound-absorbing material, and to a method for manufacturing same, having excellent sound absorption properties in which a wide surface area and an air layer are formed so as to be capable of causing viscous loss in incident acoustic energy and to improve sound absorption rate and transmission loss. Excellent sound absorption properties can be achieved even with a small fiber amount, thereby enabling lightweight design, and a binder fiber having rebound resilience is used so as to improve the sound absorption properties by maximizing the viscous loss of the acoustic energy transmitted to a fiber structure while maintaining a sufficient binding force between fibers.
