Cultured dextrose is a food additive used to inhibit the growth of undesirable bacteria and mold in food. Often used in place of benzoates and sorbates, it is considered by some consumers to be a more "natural" ingredient, because it is prepared by the fermentation of milk or sugar powders by the probiotic bacteria Propionibacterium freudenreichii and Lactococcus lactis, both of which are ...
Chocolate agar showing Francisella tularensis colonies Comparison of two culture media types used to grow Neisseria gonorrhoeae bacteria. Known as overgrowth, the nonselective chocolate agar medium on the left, due to its composition, allowed for the growth of organismal colonies other than those of N. gonorrhoeae, while the selective Thayer–Martin medium on the right, containing ...

The coccoid or bacillary bacteria can be found in soil or wet areas. They are non- sporulating bacteria and Gram-negative . Some species are also pathogenic for humans, so their detection (e.g. with analytical profile index 20 NE) has great relevance in the diagnosis of bacterial infections.
To use it in place of fresh milk, simply open a can and mix it with an equal amount of water, then replace the milk in your recipe measure-for-measure. 4. Sweetened Condensed Milk
Food microbiology is the study of the microorganisms that inhabit, create, or contaminate food.This includes the study of microorganisms causing food spoilage; pathogens that may cause disease (especially if food is improperly cooked or stored); microbes used to produce fermented foods such as cheese, yogurt, bread, beer, and wine; and microbes with other useful roles, such as producing ...
MacConkey agar is a selective and differential culture medium for bacteria. It is designed to selectively isolate gram-negative and enteric (normally found in the intestinal tract) bacteria and differentiate them based on lactose fermentation. [1] Lactose fermenters turn red or pink on MacConkey agar, and nonfermenters do not change color.
It encourages the growth of a group of certain bacteria while inhibiting the growth of others. [1] It contains a high concentration (about 7.5–10%) of salt (NaCl) which is inhibitory to most bacteria - making MSA selective against most Gram-negative and selective for some Gram-positive bacteria ( Staphylococcus , Enterococcus and ...
