Aromatic Mesophile (M235)


This product has been replaced by M244

Both cultures are almost identical, however M244 is a recent culture development that has an improved favour profile and has a higher resistance to bacteriophage.

**PLEASE NOTE: the product M235 is being phased out for M244. If you order M235 you will likely receive the equivalent size of M244. Both cutlures are nearly identical and used in the same way

  • M235 is a mix of four different strains of mesophilic cultures:
  • Lactococcus lactis subsp. Lactis
  • Lactococcus lactis subsp. Cremoris
  • Lactococcus lactis ssp Lactis biovar. diacetylactis
  • Leuconostoc mensenteroides subs. cremoris

It is a very diverse culture that can be used across many styles of cheese. It is one of the most popular of all the starter cultures.

M235 produces medium carbon dioxide gas production, medium levels diacetyl (buttery flavour) and medium citrate fermentation. M235 is like M272 but M235 is a stronger flavour and gas producer. Its primary functions are three-fold, to produce lactic acid to acidify the milk, releases quite a lot of flavour and to produce eyes or small holes in the cheese.

M235 is like M272, having Lactococcus lactis ssp diacetylactis added to create more flavour and gas production.

M235 also contains the Leuconostoc mensenteroides subs cremoris starter which is an important flavour producer because it has a unique ability to ferment the citrates in milk to produce diacetyl and aroma compounds and carbon dioxide.

  • Flavour profile: 4 out 5
  • Acid production: 3 out 5
  • Resistance to bacteriophage: 4 out 5

The 3 out of 5 rating for acid production is important where over acidification maybe a problem. For white mould cheeses, some addition of TPM (50:50 M235:TPM is a good ratio but you can choose a ratio to suit you) may be also be a good idea if over acidification is an issue. See TPM2 for more details.
