| Abstract | Clothing is easily contaminated with various soils, including triglyceride-based sebum and sweat. These triglycerides generate malodors as a result of oxidation in the air and by hydrolysis caused by lipases from the microorganisms living on our skin. This research focused on the reactions of a skin flora, Staphylococcus epidermidis, with triolein on cotton fabric. The growth rate of S. epidermidis increased with increasing concentration of the nutrient medium. The growth rate of S. epidermidis on a triolein-soiled cotton swatch was higher than that on a control swatch. FT-IR analysis of extracts from triolein-soiled cotton fabric cultured with S. epidermidis showed changes in the molecular structure of triolein. When the incubation time was increased to above 72 h, the carboxylic acid C=O stretch increased continuously, indicating continuous degradation of triolein. GC-MS was used to identify the volatile components, i.e., the odor constituents. By 168 h of cultivation of S. epidermidis on triolein-soiled cotton fabric, the amount of aldehydes had greatly increased, and unsaturated aldehydes, alcohols, and a ketone were generated. These are formed by oxidation of triolein and by enzymatic hydrolysis of ester bonds. S. epidermidis and the volatile components were removed best in the bleach-added detergent solution. The effects of laundering solutions on the removal of microorganisms were more conspicuous than on the removal of volatile components. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
