选择性培养基可以为微生物的检测、识别和计数提供更快的结果和肉眼确认
金黄色葡萄球菌检测培养基
显色培养基能够选择性检测金黄色葡萄球菌,该葡萄球菌产生的蓝绿色菌落与其他物种明显不同。
微生物学理论:培养基制备
微生物需要营养,营养是指微生物生长与繁殖所需的能量来源和特定环境条件。在自然环境中,微生物已经适应了最适合其需要的栖息地,然而在实验室中,这些要求必须通过培养基来满足。
Microbiology Theory: Media Preparation
Microorganisms need nutrients, a source of energy and certain environmental conditions in order to grow and reproduce. In the environment, microbes have adapted to the habitats most suitable for their needs, in the laboratory, however, these requirements must be met
Microbiology Quality Control in Food and Beverage
Food contaminated by microorganisms (bacteria and yeasts), viruses, and protozoa can cause severe disease.
Overview of Chromogenic Media
Selective media enable faster results and visual confirmation for the detection, identification, and enumeration of microorganisms
Vegetable and Plant Peptones: Alternatives to Animal-derived Peptones in Microbiology
Plant-based vegetable peptones are strictly of non-animal origin, so they pose no risk of carrying animal and human diseases such as BSE into fermentations and produced materials.
Media for Staphylococcus Aureus Detection
Chromogenic media enable the selective detection of S. aureus, which produce bluish-green colonies that are clearly differentiated from other species.
Cell Culture Protocol 10: Testing Cells for Mycoplasma Contamination by Hoechst DNA Staining
Cell culture protocol for testing cell lines for mycoplasma contamination using indirect DNA staining using Hoechst 33342.
Halal and Kosher Certified Culture Media for Microbial Testing
Find out about the implications of culture media carrying hidden non-halal ingredients into halal-certified production areas—and how halal-certified media avoid this risk. Perform microbiological quality control (QC) testing in halal-certified production areas without the risk of losing your certification.
Media Fills Test for Beverages
Media fill tests for beverages ensure that the filling line is not contaminated with spoilage bacteria, yeasts, or molds, during the production of low-acid aseptic beverages.
