Microalgae are characterized by rapid photoautotrophic growth and a high rate of biomass accumulation considered as an alternative feedstock for renewable energy sources such biodiesel. Biofuel research is not just matter finding the right type converting it into fuel, but also environmentally economically viable options. The paper presents results studies on use thermal mineral water medium cu...

The time-course of induction of CO(2) and HCO(3)- transport has been investigated during the acclimation of high CO(2)-grown Chlorella kessleri cells to dissolved inorganic carbon (DIC)-limited conditions. The rate of photosynthesis of the cells in excess of the uncatalysed supply rate of CO(2) from HCO(3)- was taken as an indicator of HCO(3)- transport, while a stimulation of photosynthesis on...

Biosorption of heavy metals from aqueous solution can be considered as an alternative technology in industrial wastewaters treatment. This innovative process uses biomaterials which are either abundant in nature such as algae, fungus, bacteria, moss or wastes coming from industrial production and biological processes such as fermentation. The paper presents results of studies carried out on bio...

The identification and risk assessment of potential biological invaders would provide valuable criteria for the allocation of resources toward the detection and control of invasion threats. Yet, freshwater biologists have made few attempts at predicting potential invaders, apparently because such efforts are perceived to be costly and futile. We describe some simple, low-cost empirical approach...

In this study 288 length-weight relationships of some fish species from the Turkish coasts Black Sea were gathered 138 studies, which conducted by several researchers between 1989 and 2021. For all species, “b” values ranged 2.49 for Trachurus trachurus to 3.75 Alosa caspia. The expected range 2.5<b<3.5 is confirmed fish. It thought that high b value (3.75) given A. caspia may be ...
