Cell wall canals formed upon growth of Candida maltosa in the presence of hexadecane are associated with polyphosphates.

Canals are supramolecular complexes observed in the cell wall of Candida maltosa grown in the presence of hexadecane as a sole carbon source. Such structures were not observed in glucose-grown cells. Microscopic observations of cells stained with diaminobenzidine revealed the presence of oxidative enzymes in the canals.

Modifications of the cell wall of yeasts grown on hexadecane and under starvation conditions.

Electron-microscopic examinations have demonstrated local modifications in the cell wall of the yeast Candida maltosa grown on hexadecane. In our earlier studies, these modified sites, observed in other yeasts grown on oil hydrocarbons, were conventionally called 'canals'. The biochemical and cytochemical studies of C.

Manganese tolerance in yeasts involves polyphosphate, magnesium, and vacuolar alterations.

Basidiomycetous and ascomycetous yeast species were tested for manganese tolerance. Basidiomycetous Cryptococcus humicola, Cryptococcus terricola, Cryptococcus curvatus and ascomycetous Candida maltosa, Kluyveromyces marxianus, Kuraishia capsulata, Lindnera fabianii and Sacharomyces cerevisiae were able to grow at manganese excess (2.5 mmol/L), while the growth of basidiomycetous Rhodotorula bogoriensis was completely suppressed.

[Clinical efficacy of Longidaze for the prevention of cicatricial and sclerotic complications after surgery on the upper urinary tract].

Results of surgical treatment of patients with ureteral obstruction are not always successful. Prevention of cicatricial and sclerotic complications in the postoperative period plays an important role. In this connection, search for pathogenetic methods that prevent the recurrence of strictures is one of the urgent problems of modern urology.

Microorganisms form exocellular structures, trophosomes, to facilitate biodegradation of oil in aqueous media.

Cytochemical staining and microscopy were used to study the trophic structures and cellular morphotypes that are produced during the colonization of oil-water interfaces by oil-degrading yeasts and bacteria. Among the microorganisms studied here, the yeasts (Schwanniomyces occidentalis, Torulopsis candida, Candida tropicalis, Candida lipolytica, Candida maltosa, Candida paralipolytica) and two representative bacteria (Rhodococcus sp. and Pseudomonas putida) produced exocellular structures composed of biopolymers during growth on petroleum hydrocarbons.
