Do changes in cell shape affect suspension conductivity?

The conductivity of a suspension containing uniformly oriented asymmetric cells depends on the shape of the cells. Whether the shape of cells with random spatial orientation also affects the conductivity of a suspension is not clear. A highly sensitive apparatus was used to register the dynamic changes in conductivity of erythrocyte suspension, upon induced morphological transformation discocytes<-->spherocytes). The results obtained with a sensitivity of up to 0.06% show that the drastic change of cell shape itself did not affect the suspension conductivity.

[Production and regeneration of yeast protoplasts: a review].

The latest advance in protoplast technology results from a long and detailed study of cell wall composition and protoplast systems relating to their isolation and culture. The reports on protoplast preparation and fusion discussed in this review clearly demonstrate the applicability of technique for the genetic manipulation of microorganisms. These points have been demonstrated in Candida strains. The behaviour of protoplasts especially with respect to reversion could be an additional factor that operates during selection. Furthermore the fusion technique, in providing a mechanism which genetic recombination can be readily achieved, should be of great potential in empirical breeding and strain improvement. These aspects are reviewed.
