L. lactis | MRS and [https://www.bd.com/europe/regulatory/Assets/IFU/Difco_BBL/218561.pdf M17] media are commonly used to grow L. Lactis but these are complex media that are not well-defined. In one study, two different completely defined media were formulated for L. lactis growth. The media was made by adding MOPS buffer to either BL medium or SA medium and supplementing with additional amino acids. (Jensen and Hammer, 1993) [http://www.ncbi.nlm.nih.gov/pmc/articles/PMC195913/]. | ||
L. lactis can be grown using the following carbon sources: fructose, galactose, glucosamine, glucose, lactose, maltose, mannitol, mannose, ribose, sucrose and trehalose. The growth rates are the same using glucose, mannose, galactose, sucrose, lactose and glucosamine, and slower with fructose and mannitol.

S. thermophilus has a limited capacity to utilize carbohydrates, and the primary function of S. thermophilus in industrial dairy fermentation is the conversion of lactose to lactate at elevated temperatures. S. thermophilus, unlike many other Gram-positive bacteria, prefers lactose to glucose as its primary carbon and energy source, which has led to the adaptation of the global control mechanism towards the fine-tuning of lactose uptake and subsequent catabolism by glycolysis. [...] S. thermophilus is unable to metabolize galactose (Gal−) and thus expels this sugar into the medium during lactose fermentation ( De Vin et al., 2005, Mora et al., 2002, Vaillancourt et al., 2004, Vaillancourt et al., 2008 and Vaillancourt et al., 2002). [...] The ability of S. thermophilus to produce extracellular polysaccharide (EPS) is important for the dairy industry, as it enhances the texture of fermented milk products such as yoghurt. S. thermophilus EPS consists of heterosaccharide polymers, primarily of galactose, glucose and rhamnose monomers, but N-polymers containing acetyl-galactosamine, fucose, and acetylated galactose moieties have also been reported ( Laws, Gu, & Marshall, 2001). [http://www.sciencedirect.com/science/article/pii/S0958694609002106] | |||
: This suggests we should be able to grow S. thermophilus on sucrose and glucose, but not much else. It is unusual in that it actually grows ''better'' on lactose than glucose, even though it cannot digest the galactose half of lactose. However, if we grow it on a carbon source that does not include galactose, this may significantly affect the exoplysaccharides it produces, which may affect texture. --[[User:Patrik|Patrik]] ([[User talk:Patrik|talk]]) 19:55, 26 February 2015 (EST) | |||

Quotes:
- Used in making a variety of hard, moderate temperature loving cheeses including Cheddar, Monterey Jack, Stilton, Edam, Gouda, Muenster, Blue, and Colby.
- Used in making a variety of semi-soft and fresh cheeses including Cheddar, Colby, Monterrey Jack, Feta and Chevre.
- Used in making a variety of soft ripened and fresh cheeses including Brie, Camembert, Gouda, Edam, Blue, Feta, Havarti and Chevre
- MA culture is the basic mesophilic lactic acid culture. It is the most common culture type for making cheddar, colby, Monterey jack and cottage cheese.
When added to milk, Lactococcus lactis produces lactic acid from lactose in the milk. Lactic acid works with rennet to coagulate casein to form curds for cheese production. Additionally, lactic acid lowers the pH and protects the product from undesirable bacteria and mold growth. Lactic acid is also responsible for the acidic flavor of unripened cheese.
The bacteria release proteomic and lipolytic enzymes used in ripening cheeses. Diacetyl and aldehydes produced by the bacteria produce volatile flavor compounds. Lactococcus lactis ssp. lactis also produces nisin, which acts as a natural antibiotic against different strains of Gram-positive bacteria, including Listeria, Staphylococcus and Clostridium. [1]
Growth Media
ATCC lists the following growth media:
- ATCC Medium 44: Brain Heart Infusion Agar/Broth
- ATCC Medium 260: Trypticase soy agar/broth with defibrinated sheep blood
- ATCC Medium 33: Tomato juice agar
- ATCC Medium 17: Tomato juice, yeast extract and milk
- ATCC Medium 416: Lactobacilli MRS Agar/Broth
MRS and M17 media are commonly used to grow L. Lactis but these are complex media that are not well-defined. In one study, two different completely defined media were formulated for L. lactis growth. The media was made by adding MOPS buffer to either BL medium or SA medium and supplementing with additional amino acids. (Jensen and Hammer, 1993) [2].
L. lactis can be grown using the following carbon sources: fructose, galactose, glucosamine, glucose, lactose, maltose, mannitol, mannose, ribose, sucrose and trehalose. The growth rates are the same using glucose, mannose, galactose, sucrose, lactose and glucosamine, and slower with fructose and mannitol. [3]

Quotes:
- S. thermophilis will serve as a ripening culture a bit later in the process. After the cheese is salted and in the cave, the Thermophilic cultures begin to work in a ripening capacity to break down the complex proteins into simpler components.
- Used to make Mozzarella, Parmesan, Provolone, Romano, Swiss, Gruyere, and other Italian style cheeses, which grow in higher temperature ranges.
- A Thermophilic acid producing culture for typical hard, Italian & Swiss cheeses such as Parmesan, Romano, Mozzarella, Provolone, Emmenthaler/Swiss.
- The lactic acid starter TA 60 series (GetCulture offers TA 61) are "fast" thermophilic strains of Streptococcus thermophilus (speed of acidification as compared to the TA 50 series). TA 61 is used for making Italian and Swiss cheeses such as mozzarella, parmesan, Romano, provolone, Emmental/Swiss.
- Direct-set thermophilic culture for hard, Italian & Swiss cheeses (Parmesan, Romano, Provolone, Emmental/Swiss).
S. thermophilus has a limited capacity to utilize carbohydrates, and the primary function of S. thermophilus in industrial dairy fermentation is the conversion of lactose to lactate at elevated temperatures. S. thermophilus, unlike many other Gram-positive bacteria, prefers lactose to glucose as its primary carbon and energy source, which has led to the adaptation of the global control mechanism towards the fine-tuning of lactose uptake and subsequent catabolism by glycolysis. [...] S. thermophilus is unable to metabolize galactose (Gal−) and thus expels this sugar into the medium during lactose fermentation ( De Vin et al., 2005, Mora et al., 2002, Vaillancourt et al., 2004, Vaillancourt et al., 2008 and Vaillancourt et al., 2002). [...] The ability of S. thermophilus to produce extracellular polysaccharide (EPS) is important for the dairy industry, as it enhances the texture of fermented milk products such as yoghurt. S. thermophilus EPS consists of heterosaccharide polymers, primarily of galactose, glucose and rhamnose monomers, but N-polymers containing acetyl-galactosamine, fucose, and acetylated galactose moieties have also been reported ( Laws, Gu, & Marshall, 2001). [4]
- This suggests we should be able to grow S. thermophilus on sucrose and glucose, but not much else. It is unusual in that it actually grows better on lactose than glucose, even though it cannot digest the galactose half of lactose. However, if we grow it on a carbon source that does not include galactose, this may significantly affect the exoplysaccharides it produces, which may affect texture. --Patrik (talk) 19:55, 26 February 2015 (EST)
We have purchased the following S. thermophilus strains:

- http://artisangeek.com/danisco-choozit-ta-60-62-thermophilic-starter-and-adjunct-culture/
The first one of these is actually Streptococcus salivarius ssp thermophilus. Might want to do some research on how that one differs from the strict S. thermophilus.

Lactobacillus paracasei
- "The Sacco Lyofast CA 35 consists of a propietory strain of Lactobacillus.paracasei. This helpful non-starter lactic acid bacteria (NSLAB) is beneficial in all aged cheese styles. It intensifies flavor and aroma, accelerates ripening, reduces bitterness, improves overall texture -and is very helpful in preventing contamination from unwanted elements. As a non-starter culture, acid production is not significant enough to alter the acidity profile of the cheese".

Geotrichum candidum
http://www.cheesemaking.com/shop/geotrichum-candidum-white-mold-powder-1-pack.html
Quotes:
- This mold powder will produce a white to cream color surface and it plays a significant role in the ripening process for surface ripened cheese of the soft ripened or washed rind types. It greatly influences the appearance, structure and flavor of Brie and Camembert, along with a variety of goat cheeses. It also helps prevent the skin from slipping off of your cheese. In red smear cheeses it helps neutralize the surface of the cheese and stimulates the development of desired, acid-sensitive flora such as P.candidum.
- Geotrichum can also be used in conjunction with Brevibacterium linens to creat the right conditions for the formation of the surface smear on washed rind cheeses.
