Methods for concentrating the cell suspension of Chlorella microalgae for obtaining pigment complex
The aim of this work was to study the influence of various techniques of concentrating the наличе Chlorella microalgae cell suspension on the obtained biomass output, composition and spectralExpand
Aquabiotechnology of directed cultivation of microalgae Chlorella sorokiniana biomass
We carried out cultivation of Chlorella sorokiniana microalga using various irradiation sources: daylight lamp with spectral range 530-610 nm and filament lamp with spectral range 3.5-5.0 ?m.Expand
Role of microbiocenosis of the gastrointestinal tract in the nutrition of grouse
In both species of birds, nitrogenase and cellobiohydrolase activities were discovered in the digestive tract, with the maximum observed in the cecum. Expand
Soil biological activity in the Chernye Zemli, Kalmykia, inhabited by gerbils Meriones tamariscinus and M. meridianus
Functional biodiversity of the microbial community was evaluated using multisubstrate testing and comparison of bacterial group composition in samples from gerbil burrows by mediated by the changes in the group composition of microorganisms. Expand
Microbial nitrogen fixation in the gastro-intestinal tract of Kalmykia gerbils (M. tamariscinus and Meriones meridianus)
The nitrogen-fixing activity, nitrogen (N) and carbon (C) contents, and the number of microorganisms in the forestomach, cecum, and colon were detected in two gerbil species, granivorous MerionesExpand
Nitrogen-fixing microorganisms in the hare gastrointestinal tract
The activity of nitrogen fixation in the gastrointestinal tract of hares (Lepus europaeus) in different periods of their feeding activity is demonstrated and the functional imporr tance of the microorganisms found has not been clarr ified. Expand
Diazotrophs in the digestive tract of termite Neotermes castaneus
This is the first demonstration of significant changes in the complex of aerobic and facultatively anaerobic nitrogen fixers mediated by an extension of microbial group composition and a shift in dominant taxa in termites that cannot reutilize their feces. Expand
Morphological provision for the specialization of hares to coprophagy: The architectonics of the mucous surface of the intestine
The macrostructure of the surface of the mucous membrane of the gastrointestinal tract were studied in detail in two hare species using scanning electron and digital microscopes and the particularities of the architectonics of the membranes that are specific for hares were revealed. Expand
The effect of coprophagy on the size of plant fibers in the digestive tract of hares Lepus europaeus and L. timidus (Lagomorpha, Leporidae)
It was shown that repeated passage of food through the digestive tract compensates small volume of the cecum and increases the period of digestion of the same portions of food. Expand
A method for obtaining plastid pigments from the biomass of Chlorella microalgae
Microalgae are distinguished from land plants by the high content of plastid pigments and the biodiversity of carotenoids. The aim of this study is to develop a technology for extracting a pigmentExpand
