Planctomyces Cultivation

Planctomyces Cultivation

The cells of Planctomyces are spherical to oval or pear-shaped, 0.3-1.7μm in diameter with long and slender stalks at the mature stage. Among them, the shank width is 0.3-0.9 microns, and the length can reach 11 microns, which may be formed by the secretion. They often attach to their cylindrical fixators, thus forming rosettes of up to 50 cells. Older parts of the stalk (in the center of the flower) may have iron deposits, which then thicken the base of the stalk. Mature cells are occasionally smaller, and immature cells multiply by terminal or lateral budding. Planctomyces appear primarily in the fall on the oxygenated surface layer of the lake.

Planctomyces Culture Service

Creative Biogene offers customizable Planctomyces strain culture services. This service can help you obtain Planctomyces cultures for subsequent scientific research. This service allows you to skip the complicated and tedious groping of culture conditions, which helps to speed up research on this strain.

Planctomyces bekefii

The mature cells of Planctomyces bekefii are spherical, 1.4-1.7 μm in diameter, attached to a slender stalk that radiates from a common center to form a flower. Propagation by various budding is often performed on the ends or sides. The cells of Planctomyces bekefii are colorless. Smaller individuals stained uniformly and were Gram-positive. Larger and older cells were Gram-negative and darkly stained at the ends. The shank is slightly flexible and varies in length. Cells can fall off the stalk. The older part of its stalk is covered with iron.

Planctomyces bekefii is a heterotrophic, psychrophilic, aerobic bacterium. Originally observed in plankton in Lake Lagymanyos (Budapest, Hungary). Widely distributed in oxygen-rich parts of freshwater lakes.

Planctomyces condensatus

Cells of Planctomyces condensatus are spherical, 0.7-1.7 μm in diameter, colorless, and attach in groups to a common center that may contain iron deposits. The bacteria occasionally appear as short, thin, gelatinous stems. Its buds are terminal. The bacterial cells appear to be broken into 2 to 4 gonidiophore. Originally found at a depth of 13.5 m at Lake V uolep Njakajaur (northern Sweden). Found many times in freshwater lakes in Michigan (USA).

Planctomyces kljasmensis

The cell of Planctomyces kljasmensis are spheroid shaped to oval, 0.3-0.5μm in diameter. The stipe is slender and often coated with ferric hydroxide. Oval cells are attached with their long axis perpendicular to the axis of the main stalk. Rosettes as many as 50 cells have been observed. Propagation by budding. Originally found in plankton in the Kryazma Reservoir near Moscow, Russia.

Planctomyces gracilis

The cells of Planctomyces gracilis are spherical, 0.3-0.6 microns in diameter. The stalk is slender (0.3-0.4 µm in diameter), up to 11 µm long, crescent-shaped, and joined at the base to form a small rosette. Originally found in autumn in plankton in fish ponds in Buzsak (Hungary).
