Germination of the seeds of lettuce using the aquaponic method
The present article shows the data about the germination of the seeds of lettuce wetted with various kinds of water, namely, tap water, water from the river, water from fish tanks, and that from a well. The germination rate of the seeds wetted with the tap water was 94 %, with the water from the river β 97 %, and with the water from the well β 99 %. The highest germination rate was observed in the sample wetted with the water from a fish tank; it reached 100 %. At the end of the experiment the sprouts in the test samples 2.2 times exceeded the reference, by 69.0 and 63.7 %, respectively, which is evidence that germination of the seeds wetted with the water from a fish tank, from the river, and from the well accelerates germination of lettuce seeds. At the end of germination, the average number of leaves in the third and the fourth groups exceeded the reference value by 13.6 %; and in the second group, the number of leaves was greater by 11.4 % than in the reference group. This is evidence that the shoots wetted with the water from the river and a fish tank developed most intensively

This study was aimed at comparing the effect of enzymatic modification of the protein isolates obtained from sunflower cake on their fractional composition. The obtained chromatograms show that electrophoretic fractions of the modified protein isolates are substantially different from the initial protein isolates. The chromatogram of the proteins modified by sunflower sprouts (SS) showed the presence of 11 fractions represented by 17 peaks (with the total area of 39.65 mAUΓsec), the chromatogram of a protein isolate modified by whey lactoserum (WLS) β of eight fractions and 19 peaks (with the total area of 28.73 mAUΓsec), and the chromatogram of a complex enzymatic modification β of 13 fractions and 21 peaks (with the total area of 24.20 mAUΓsec). Thus, a comprehensive modification caused the differentiation of the first fraction from three peaks with the total relative area of 18.7 % to five peaks with the area of 13.6 % from the total relative area of the peaks of fractions of the corresponding protein product. With that, the comprehensive enzymatic modification and modification of SS resulted in increasing the speed of peaks separation by six minutes, compared to the native protein product, and the modification of WLS reduced the duration by 4.5 minutes. Therefore, reducing the molecular weight and changing the fractional composition of proteins is achieved by the action of proteolytic enzymes of vegetative and microbial origin.Π‘ΡΠ°Π²Π½Π΅Π½ΠΈΠ΅ Π²Π»ΠΈΡΠ½ΠΈΡ ΡΠ΅ΡΠΌΠ΅Π½ΡΠ°ΡΠΈΠ²Π½ΠΎΠΉ ΠΌΠΎΠ΄ΠΈΡΠΈΠΊΠ°ΡΠΈΠΈ Π±Π΅Π»ΠΊΠΎΠ²ΡΡ
