The dirigibility of thought

I

Two yeasts met in the woods and one of them took the road less traveled by and it made all the difference.
The roads are the divergence point in the phylogenetic tree ca. 200 Mya ago.
(Robert Frost’s original poem is some what different)
But what is beyond ?
Is it possible to have an immortal yeast, just like a HeLA cell ?
What happens to mitochondria in industrial yeast strains ?
If yeasts are perennially fermenting in open industrial vats, is it not expensive for the cells to invest energy in genes that it may never use ?

PE-2 and CEN.PK meeting 9: Outuno

Gosh it has indeed been a long time. Yes it is. Yes it is. So comment Petruska and Seine meet after their long break.

Was it hard they surmise ?

PE-2 and CEN.PK meeting 8: Spring

Petruska and Seine see each other after a long summer vacation.

Our heart melts listening to the mellifluous voice of Nina. Petruska asked Seine to watch this video of the sugarcane cutters who form alphabets in English, by twisting, bending and curling the intractable cane,

PE-2 and CEN.PK meeting 4: Observations

CEN.PK and PE-2 had a lull period last week. They learn that Vijay is waiting for the nitrogen cylinder with 99.999% purity. Vijay needs the nitrogen gas to maintain anaerobicity in the culture medium. It costs 450 Reais for 10 m^3 of gas.

PE-2: Seine, I have so many observations and questions to share and I wonder if one generation time is sufficient to share them all with you.

Generation time is the time taken for the mother cell to become a daughter cell.  It is equal to 0.693/mu, where mu is the growth rate of the organism under the given conditions. Growth rates made easy !

Petruska contines to speak…

When we, I mean our hexose transporters, transport  glucose, do we act cooperatively like the human beings ?  Do we have friends ? Would we want friends ? Continue reading “PE-2 and CEN.PK meeting 4: Observations”
