1. Lactic acid bacteria: Commonly found in buttermilk are various strains of lactic acid bacteria such as Lactococcus lactis, Streptococcus thermophilus, and Lactobacillus bulgaricus. These bacteria are responsible for the fermentation process that converts lactose into lactic acid, giving buttermilk its tangy flavor and thick texture.
2. Yeast: Some species of yeast, such as Candida milleri and Kluyveromyces lactis, can also be found in traditional buttermilk. These yeasts contribute to the fermentation process by breaking down sugars and producing carbon dioxide, which helps to give the buttermilk its characteristic consistency and slight effervescence.
3. Heterofermentative bacteria: In addition to lactic acid bacteria, buttermilk can also contain other species of bacteria such as Leuconostoc mesenteroides and Lactobacillus brevis. These bacteria are capable of producing other acids besides lactic acid, adding to the overall flavor complexity of the buttermilk.
4. Molds: Occasionally, molds may be present in traditional buttermilk, such as species of Penicillium, Geotrichum, or Issatchenkia. These molds may have beneficial effects on flavor development and contribute to the aromatic characteristics of the buttermilk.
5. Acetic acid bacteria: Although less common, some strains of acetic acid bacteria, such as Acetobacter and Gluconobacter, can be found in buttermilk. These bacteria can produce acetic acid, which may give the buttermilk a slightly tart or vinegary taste.
It's worth noting that the composition of microorganisms in buttermilk can vary depending on various factors such as the manufacturing process, regional traditions, and the source of the milk used.

Types of microorganisms commonly found in lassi
1. Lactic acid bacteria: Lassi is a traditional yogurt-based drink, and the primary microorganisms found in lassi are lactic acid bacteria. This includes species such as Lactobacillus acidophilus, Lactobacillus bulgaricus, Lactobacillus casei, and Streptococcus thermophilus. These bacteria ferment the milk sugars and produce lactic acid, giving lassi its tangy flavor and thick texture.
2. Yeast: Some strains of yeast can also be present in lassi. These yeasts, such as Saccharomyces cerevisiae and Kluyveromyces lactis, contribute to the fermentation process and enhance the flavor complexity of the drink.
3. Heterofermentative bacteria: Similar to buttermilk, lassi may contain heterofermentative bacteria like Leuconostoc mesenteroides and Lactobacillus brevis. These bacteria produce various acids alongside lactic acid, which adds to the overall taste profile of the lassi.
4. Acetic acid bacteria: Occasionally, lassi may have some acetic acid bacteria present, including species like Acetobacter and Gluconobacter. These bacteria can convert alcohol into acetic acid, potentially contributing a slight vinegar-like taste to the lassi.
5. Mold and other bacteria: While less common, molds and other bacteria may be present in lassi, similar to other fermented dairy products. These may include species of Penicillium, Geotrichum, or Issatchenkia, among others. These microorganisms can influence aroma and texture, adding to the diversity of flavors in lassi.
It's important to note that the specific composition of microorganisms in lassi can vary depending on the region, preparation method, and individual preferences. Additionally, commercial lassi products may undergo pasteurization, which can affect the presence and activity of microorganisms.
