Scientific Head: Tatyana Yuryevna Orlova, a leading researcher, Cand. Sci. Biol., senior researcher, has managed the Laboratory since 2017.
Main fields of research:
- Study of microalgae biodiversity in the Far Eastern seas of the Russian Federation.
- Monitoring of harmful algae and biotoxicity in marine waters of the Far Eastern seas.
- Study of biodiversity of marine filamentous fungi and heterotrophic organisms.
- Study of marine microbiomes and interaction of their components (microalgae and associated fungi and bacteria) with each other.
- Search for bacteria producing physiologically active substances. Analysis of toxicity of bacterial isolates using various biological models.
- Cultivation of marine microalgae and microorganisms.
- Collection, documentation, and deposition of biological specimens in compliance with international biobanking standards and using up-to-date equipment.
Approaches and methods used:
- Method for classical identification of plankton and benthic microalgae based on morphological traits and using light and electron microscopy.
- Method for obtaining and maintaining dinoflagellate cultures from resting cysts.
- Methods for cultivating dinophytes, diatoms, raphydophytes, cryptophytes, and green algae.
- Method for studying the structure of fungi using transmission light microscopy.
- Method for determining the level of domoic acid in laboratory-reared cultures of diatoms through competitive enzyme immunoassay.
- Methods for counting number of cells, measuring the optical density of solution (absorbance), and determining the intensity of fluorescence at a specified emission wavelength using multi-well plates or a cuvette module on a Spark 10M Tecan multimode microplate reader.
- Methods for isolating bacteria from various natural objects, their cultivation and identification.
- Method for analyzing antimicrobial properties of bacteria.
- Method for analyzing bacterial antibiotic resistance.
