Influence of selenium nanoparticles on basic cultivation parameters and phytostimulating properties of Lactococcus lactis
... the MRS medium did not result in statistically significant differences in the inhibition zones of phytopathogenic bacteria. A stimulatory effect of L. lactis IMB B-7352, cultivated on MRS medium supplemented with nanoselenium, was demonstrated on the growth parameters of wheat and pea plants. It was established that nanoselenium concentrations of 0.25—0.5 mg/L in the MRS medium are optimal for promoting plant growth. For the first time, the effectiveness of nanoselenium supplementation in the cultivation ...
Experimental assessment of the influence of certain aspects of baltic herring spawning on the model species of cladocerans
Experiments were conducted to investigate the influence of gametes and water collected from spawning aggregations of the Baltic herring Clupea harengus membras in the Vistula Lagoon on the survival, growth, molting frequency, number of eggs in the brood chamber, and offspring production of the model planktonic crustacean species Daphnia magna. In the first series of experiments, a fixed volume of a suspension of gametes from male and female Baltic ...
The influence of temperature regime and spectral composition of light on the growth of biomass of the cyanobacterium Cyanobacterium sp. B-1200
... cultivation conditions for cyanobacteria will contribute to the rapid accumulation of bacterial biomass and maximize the yield of biologically active substances. This study analyzes the influence of temperature and light spectral composition on the growth of the cyanobacterium Cyanobacterium sp. IPPAS B-1200 under stationary conditions. The strain was cultivated under different temperatures and light conditions, with regular optical density measurements to monitor biomass growth.
A detailed analysis ...
