Significant Difference

This work investigates the concentration of some trace elements in freshwater microalgae ( Chlorella vulgaris and Spirulina platensis) through total reflection x-ray fluorescence spectroscopy (TXRF). Slurry samples were prepared from 3.4 ± 0.5 to 9.8 ± 0.5 mg of freeze-dried algae biomass for direct metals analysis. Gallium was used as internal standard at concentration of 500 µg/L and the solution was mixed for 15 second using vortex. The concentrations of different metals including Magnesium (Mg), Zinc (Zn), Phosphorus (P), Sulphur (S), Copper (Cu), Potassium (K), Calcium (Ca), Manganese (Mn) and Iron (Fe) were determined in the ranged 6.8 ± 1.7 – 15709 mg/kg. A similar study investigated the total macro and micronutrient profile Chlorella vulgaris and the published data agree with current study. Statistical analysis shows that only Ba has significant difference between Chlorella vulgaris and Spirulina platensis (P = 0.05) The two investigated algal species shows a measurable concentration using TXRF of metals such as manganese, iron, copper, and zinc. TXRF shows good accuracy with ability to determine sample in small quantities (µl) In conclusion, the sensitivity of TXRF technique can also be seen in determining elements with lower atomic number such as Ca, P and K.

This research investigated Spirulina Platensis, Chlorella vulgaris and Artemia salina as additional sources of protein and biologically active substances that affect the parameters of the carp body. Additional addition of carp to the diet in the ratio: Spirulina Platensis - 40%, Chlorella vulgaris - 30% and Artemia salina - 30% made an impact on the parameters of carp development. The components were cultured in a bioreactor built into a recirculating aquaculture system. The results showed that after additional feeding of carp with the indicated components, the body weight of one-year carp was higher than the control group by 8.9%, and safety by 3.4%. Body weight two year carp was greater in the experimental group than in the group where the fish ate the total diet. The difference was 12.1% in body weight and 2.9% in safety. These parameters were significantly lower in fish fed the control diet (P<0.05). This scientific work has demonstrated the additional use of natural food as a method for improving the blood composition of carp: an increase in hemoglobin by 15.5% (P<0.05), erythrocytes by 5.5% in comparison with the control group. Indicators of gas-discharge visualization of a biological object supplemented the obtained result.
