  2. Saccharomyces cerevisiae - Wikipedia

    en.wikipedia.org/wiki/Saccharomyces_cerevisiae

    Saccharomyces cerevisiae (/ ˌ s ɛr ə ˈ v ɪ s i. iː /) (brewer's yeast or baker's yeast) is a species of yeast (single-celled fungal microorganisms). The species has been instrumental in winemaking, baking, and brewing since ancient times. It is believed to have been originally isolated from the skin of grapes.

  3. Yeast - Wikipedia

    en.wikipedia.org/wiki/Yeast

    [5] [6] Yeast sizes vary greatly, depending on species and environment, typically measuring 3–4 μm in diameter, although some yeasts can grow to 40 μm in size. [7] Most yeasts reproduce asexually by mitosis, and many do so by the asymmetric division process known as budding.

  4. Microbial food cultures - Wikipedia

    en.wikipedia.org/wiki/Microbial_food_cultures

    Microbial food cultures are live bacteria, yeasts or moulds used in food production. Microbial food cultures carry out the fermentation process in foodstuffs. Used by humans since the Neolithic period (around 10 000 years BC) [1] fermentation helps to preserve perishable foods and to improve their nutritional and organoleptic qualities (in this case, taste, sight, smell, touch).

  5. Bacterial growth - Wikipedia

    en.wikipedia.org/wiki/Bacterial_growth

    Bacterial growth curve\Kinetic Curve. In autecological studies, the growth of bacteria (or other microorganisms, as protozoa, microalgae or yeasts) in batch culture can be modeled with four different phases: lag phase (A), log phase or exponential phase (B), stationary phase (C), and death phase (D). [3]

  6. Zygosaccharomyces bailii - Wikipedia

    en.wikipedia.org/wiki/Zygosaccharomyces_bailii

    For example, by utilizing acetic acid, the yeast can raise the pH of pickles sufficiently to allow the growth of less acid-tolerant bacteria. [5] Besides, as with other yeasts, the concentration of fermentable sugar in a product affects the rate of spoilage by Z. bailii , e.g. the yeast grows faster in the presence of 10% (w/w) than 1% (w/w ...

  7. Komagataella - Wikipedia

    en.wikipedia.org/wiki/Komagataella

    The two yeast genera; Pichia and Saccharomyces, have similar growth conditions and tolerances; thus, the culture of Komagataella can be adopted by labs without many modifications. [15] Moreover, unlike S. cerevisiae , Komagataella has the ability to functionally process proteins with large molecular weight, which is useful in a translational ...

  8. Agar plate - Wikipedia

    en.wikipedia.org/wiki/Agar_plate

    An agar plate is a Petri dish that contains a growth medium solidified with agar, used to culture microorganisms. Sometimes selective compounds are added to influence growth, such as antibiotics. [1] 96 pinner used to perform spot assays with yeast, fungal or bacterial cells

  9. Growth curve (biology) - Wikipedia

    en.wikipedia.org/wiki/Growth_curve_(biology)

    Figure 1: A bi-phasic bacterial growth curve.. A growth curve is an empirical model of the evolution of a quantity over time. Growth curves are widely used in biology for quantities such as population size or biomass (in population ecology and demography, for population growth analysis), individual body height or biomass (in physiology, for growth analysis of individuals).
