Tests microbiologiquesIndex. décimale : 667.6 Peintures Résumé : Limitations of correct microbiological techniques in many industries including paint industries had led to the underestimation of the potential threat of microbiological origin. It leads to difficult to explain kind of situation in spoilage of end product like paint which although substantiated with presence of biocides. Although it has been a well established fact that in many natural environments approximately 1% of microbes can be readily cultivated in lab still standard industrial practices rely upon conventional approach for microbial enumeration. Conventional approach which utilizes nutrient rich media for cultivation of bacteria can only represent very small portion of the actual bacterial population of tested raw material. In this study it has been observed that bacterial population can be increased with dilution of the nutrients in conventional nutrient media. Note de contenu : - Paint sample

Tests microbiologiquesIndex. décimale : 668.5 Parfums et cosmétiques Résumé : Cleaning of plants as well as hygienic filling are essential processes for ensuring product safety. However, many cleaning processes have been determined empirically and offer enormous potential for saving resources. The use of specific sensors enables a control of the cleaning success and in this way a specific optimization of the processes with regard to the duration, frequency and use of cleaning media. A microbiological validation of sterilization and hygienic filling systems also serves as proof of process efficiency and as a basis for further optimization steps. For this purpose, microbiological challenge tests are carried out using specific test organisms. Resistance-tested bio-indicators are a prerequisite for proving the real efficiency of sterilization processes. Note de contenu : - Sensor systems increase cleaning efficiency
- Macroscopic cleaning validation
