[Effect of chromium (VI) on growth physiology and sorptional capacity of yeast].

Resistance of 7 yeast species (7 strains) to various chrome concentrations in the medium and their sorptional activity have been studied. It is shown that the biomass of the yeast Williopsis californica UKM-248, Candida krusei UKM-61t under their concentration in the medium of 200 and 500 mg/l of Cr6+ is 0.74 and 0.

[Search of heavy metals biosorbents among yeasts of different taxonomic groups].

The use of microbial cells as heavy metal biosorbents is a potential alternative for the existing methods of the environment treatment for pollution by these metals. Yeast may be successfully used in the metals sorption. An agar-plate screening method was used for rapid isolation of metal-accumulating strains of yeast and preliminary estimation of their biosorption capacity.

[Yeasts--biosorbents of heavy metals].

The sharp increase of the level of environment pollution by heavy metals caused the increase of interest to the problem of live organisms (including microorganisms) resistance to these metals. Biosorption is one of the mechanisms of microorganisms resistance to heavy metals. Yeasts as biosorbents are of special interest.

[The state of the hepatobiliary system and the pancreas in patients with eczema and neurodermatitis].

Ultrasonic scanning of the digestion organs, carried out in 35 patients with eczema and 20 ones with diffuse neurodermatitis have revealed abnormalities of the liver echostructure in 60% of patients with eczema and in 50% of neurodermatitis patients; abnormal gallbladder echostructure in 65.7% of eczema patients and in 25% of neurodermatitis patients; disturbed echostructure of the pancreas in 34.3% of eczema patients and in 5% of neurodermatitis patients.
