Enzymatic Activity Measurements in Streptococcus Thermophilus
Enzymatic Activity Measurements in Streptococcus Thermophilus
8 Jul 2015This application note measures the b-galactosidase and lactate dehydrogenase activities in Streptococcus thermophilus cells to evaluate the effect of carbon dioxide availability on the homolactic fermentation process. Streptococcus thermophilus is a major component of dairy starter cultures used for the manufacture of yogurt and cheese. The Precellys® 24 allow for simple and efficient homogenizing of the sample for accurate and precise data.

Sample PreparationSample preparation can improve the quality and speed of separation techniques. Products to assist sample preparation include filtration equipment, evaporators, membranes and sieves.Cell / Tissue CultureCell culture or tissue culture is used to study the biology of cells or tissues and to isolate cellular products in an environment which can be manipulated and well defined. Accurately control your culture environment with bioreactors or culture incubators, bind your cells to a surface or together with an extracellular matrix. Distinguish cell types with differential media or proliferate cells with certain characteristics using selective media. Enrich your media with supplements such as growth factors, sera and vitamins. Find the best cell and tissue culture products, kits and equipment in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.MicrobiologyMicrobiology is the study of microorganisms including protists, prokaryotes, fungi, and, often, viruses. Microorganisms are a useful research tool as genetic vectors and, in immunology, for antibiotic susceptibility testing, cellular biology and genetics. Microorganisms commonly grow readily in incubators with microbial culture media; this can contain chromogenic supplements to differentiate between cell lines. Estimate your culture’s density of microorganisms with colony counters, or screen and select colonies for desirable clones with automated colony pickers. Additionally, equipment is available to monitor environments for the presence of microbes and identify with microbial identification instruments.

Typical instrumentation includes blanchers, color sorters, cookers, grinders, and refrigeration. These are used to replicate the processes commonly used in the commercial preparation of food and beverages.Homogenizers and BlendersHomogenizers and blenders are used to homogenize various types of material, including tissue, cells, plants, food, soil, biological and chemical samples for subsequent analysis. Lab equipment for sample homogenization includes handheld and benchtop homogenizers, bead mill, ultrasonic and multiple sample homogenizers, high shear homogenizers and blenders. Homogenizer bead and probe multipacks are available to avoid cross contamination of samples, as well as cooling systems for homogenizing temperature-sensitive samples. Homogenizers are often used in the first step of extraction of DNA, RNA and proteins from tissue and cell samples. Find the best homogenizers and blenders in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Bioprocessing / FermentationBioprocessing is the use of biological materials to perform commercial, scientific or medical research processes. Biological materials used include cells, enzymes and organisms. Usually bioprocessing requires a batch or continuous bioreactor such as a fermentor or cell culture system. The advantages of using a reactor include high productivity, easy configuration, adjustable values and automation.Sample HomogenizerFood TestingFood testing refers to a variety experiments including PCR, mass spectrometry, processing, QuEChERS, analyzing and Kjeldahl.MicrobiomeMicrobiome research focuses on the complex communities of microorganisms living in and on humans, animals, plants, and environments. It plays a crucial role in health, disease, and ecological balance. Explore tools and resources for microbiome analysis, including sequencing platforms and bioinformatics software.Enzymes
