Subject: Was:: does kefir grains evolve? [microflora, and size or weight of kefir grains]

Hi Nori,

I hope you have digested the info I shared in my last reply, without suffering any indigestion in the process ūüėČ Otherwise I suggest to sip the info with a slurp of kefir.
Here is a list of organisms isolated from kefir grains, which is similar to the list found on Dom’s Kefir in-site:

L. casei – Homo-fermentative [responsible for 90% of lactate synthesis]
L. paracasei – Homo-fermentative
L. acidophilis – Homo-fermentative
L. hilgardi -Hetero-fermentative [responsible for 50% of lactate synthesis]
L. delbruechkii subsp. bulgaricus – Homo-fermentative
L. kefiranofaciens – Produce Kefiran, internaly within the matrix
L. kefyri – Synthesizes kefiran superficially [possibly controlls microflora]
L. desidiosus – Heterofermentative [ferments L-arabinose and gluconate]
L. brevis [Synthesizes polysaccharide]
