Study with quizlet and memorize flashcards containing terms like what type of media is this, e. coli, e. aur and more. micro lab (3): selective & differential.
Micro Lab 3 Selective Differential Media Flashcards Quizlet Study with quizlet and memorize flashcards containing terms like the substance(s) that inhibit gram positive on emb are, the differential property of msa is?, which species of bacteria produces a metallic green sheen when growing on emb? and more. Selective agent is 7.5% nacl, or salt. selects for halo tolerance and against non halo tolerant organisms. plasmolysis, or cremation, due to water loss, depending on whether they have a cell wall. allows staphylococcal species to grow since they are halotolerant. differential agents are phenol red, or the ph indicator, and mannitol, or sugar. Differential media where variations are based on hemolytic reactions contains 5% sheep blood, which helps in cultivation of fastidious bacteria such as streptococcus, by observation of hemolysis a hemolysis = partially oxidize hb green pigment b hemolysis= completely oxidize hb transparent g hemolysis= no oxidation of hb no change in agar. Study with quizlet and memorize flashcards containing terms like growth can be performed by adding certain nutrients that are more easily used by one type of micro organisms in another, microbial growth can also change the mediums ph, leading to a color change of the dye present in a ph indicator. media containing these guys are called , media are able to support the growth.

Terms in this set (56) what does differential media do? differentiates between bacteria based on metabolic processes. what does selective media do? contains an additive that will promote or inhibit growth of a type of bacteria. true or false? a media can be both selective and differential. true. Used to discriminate between closely related organisms using differences in characteristic growth patterns or biochemical changes. combines aspects of both selective media and differential media. specifically inhibits the growth of some organisms while allowing others to grow. dyes and or chemicals added to distinguish biochemical.
