Rhodopeptins (Mer-N1033), novel cyclic tetrapeptides with antifungal activity from Rhodococcus sp. I. Taxonomy, fermentation, isolation, physico-chemical properties and biological activities

Five novel cyclic tetrapeptides, named rhodopeptin C1, C2, C3, C4 and B5, were isolated from a strain named Rhodococcus sp. Mer-N1033. They are a novel type of cyclic tetrapeptide composed of a beta-amino acid and three usual alpha-amino acids. Rhodopeptins show high in vitro antifungal activity against Candida albicans and Cryptococcus neoformans, whereas they show no activity against bacteria.

Distribution of motoneurons innervating tail muscles in the pigeon

The distribution of motoneurons innervating the tail muscles, M. levator caudae, M. depressor caudae, M. pubocaudalis externus, M. pubocaudalis internus, M. lateralis caudae and M. flexor cruris, in the adult pigeon was examined by retrograde transport of horseradish peroxides. Labeled motoneurons innervating tail muscles were distributed in the longitudinal column of the spinal cord below the sacral spinal segment 5. The average diameter of cell bodies ranged from 23.7 to 62.5 microns. Each motoneuron pool was localized in a characteristic position in the ventral horn.

Location of motoneurons supplying tail muscles in the domestic fowl

The distribution of motoneurons innervating the tail muscles, levator caudae, depressor caudae, pubocaudalis externus, pubocaudalis internus, lateralis caudae and flexor cruris, in the adult domestic fowl was examined by retrograde transport of horseradish peroxidase Labeled motoneurons supplying tail muscles were distributed in longitudinal column in the spinal cord below sacral spinal segment 3 and average diameters of cell bodies ranged from 27 to 59 microns. Each motor pool was localized in a characteristic position in the ventral horn.

Mer-WF3010, a new member of the papulacandin family. I. Fermentation, isolation and characterization

Mer-WF3010, a new member of the papulacandin family, was isolated from the mycelia of Phialophora cyclaminis Mer-WF3010 (FERM P-11475). The molecular formula of Mer-WF3010 was determined as C45H60O16.
