Notes: [Auszug] We are unaware of any work showing dehydroxylation of caffeic acid by pure cultures of micro-organisms. We have isolated a strain of Pseudomonas sp. from rat faeces which has the ability to dehydroxylate caffeic acid yielding both m-hydroxy-phenyl-propionic and m-cournaric acids, as well as some ...

Notes: SYNOPSIS. The process of conjugation in a strain of Stylonychia muscorum Kahl is described. It follows the general pattern reported earlier in other Oxytrichidae, but the following peculiarities can be noted: 1) mating never occurs between individuals possessing only two micronuclei, 2)exchange of small macronuclear lobes can be occasionally observed, and 3) the reorganization of the exconjugants involves the quick, successive passage of a series of reorganization bands.
