The purpose of the study:
The study of the interaction of human biological media with nutrient media.
Test samples:
- Sample of saliva on an empty stomach from 08.02.2023.
- Nutrient medium (raw melon) combined with human biological medium (saliva) from 08.02.2023.
- Fasting saliva sample from 03.03.2023.
- Nutrient medium (raw melon) combined with human biological medium (saliva) from 03.03.2023.
The assessment was carried out immediately after collecting samples, after 3-5h, 1d, 2d, 3d and 4d.
Additional sample №2 was studied on the 6th day, and samples №3 and №4 on the 5th.
Sample №1:
| Description | Photo |
| 08.02.2023 16:00 The saliva sample contains many medium-sized bubbles grouped together. According to the size and nature, it can be concluded that the surface voltage of the biofilm and the electrical activity of the bacteria that make up the biofilm are high. |  |
| 08.02.2023 20:00 There is a union of bubbles. |  |
| 09.02.2023 16:30 The dynamics of combining bubbles into one big one continues. |  |
| 10.02.2023 22:00 The liquid is almost absent as a result of drying of the sample. |  |
| 11.02.2023 20:00 The dynamics of an increase in a large bubble continues. |  |
| 12.02.2023 17:00 Complete drying of the sample. There is no need for further observation. |  |
Sample №2.
| Description | Photo |
| 08.02.2023 19:00 A sample of a nutrient medium combined with saliva contains many small and medium-sized bubbles combined into a group. According to the size and nature, it can be concluded that the surface voltage of the biofilm and the electrical activity of the bacteria that make up the biofilm is average. |  |
| 08.02.2023 23:00 Some bubbles burst. There is a union of bubbles. |  |
| 09.02.2023 16:30 The dynamics of bubble unification continues. The bubbles are separated from each other – there are practically no chains. |  |
| 10.02.2023 22:00 The dynamics of bubble unification continues. |  |
| 11.02.2023 20:00 The dynamics of bubble unification continues. The largest one burs. |  |
| 12.02.2023 17:00 The dynamics of bubble unification continues. There are no chains.There is partial drying of the sample and thickening of the liquid between the bubbles. |  |
| 14.02.2023 3:00 It is obvious that the dynamics of combining bubbles into one large burst continued. The drying of the sample continues. There is a slight growth of bacteria, but the liquid flows well. |  |
Sample №3
| Description | Photo |
| 03.03.2023 10:30 The saliva sample contains many medium- and small-sized bubbles grouped together. According to the size and nature, it can be concluded that the surface voltage of the biofilm and the electrical activity of the bacteria that make up the biofilm is high. |  |
| 03.03.2023 15:00 There is a union of bubbles into one big one. |  |
| 04.03.2023 8:00 he dynamics of combining bubbles into one big one continues. |  |
| 05.03.2023 10:30 The dynamics of combining bubbles into one big one continues. Most of the bubbles burst. |  |
| 07.03.2023 14:00 The separation of large puzery into separate bubbles is observed. |  |
| 08.03.2023 14:00 All the bubbles combined into one big one again. |  |
Sample №4.
| Description | Photo |
| 03.03.2023 12:00 A sample of a nutrient medium combined with saliva contains many medium- and small-sized bubbles combined into a group. According to the size and nature, it can be concluded that the surface voltage of the biofilm and the electrical activity of the bacteria that make up the biofilm are high. |  |
| 03.03.2023 15:00 There are no changes. |  |
| 04.03.2023 8:00 There are no changes. |  |
| 05.03.2023 10:30 There is a process of combining bubbles into one big one. |  |
| 07.03.2023 14:00 The dynamics of combining bubbles into one big one continues. There was a drying process of the sample. |  |
| 08.03.2023 14:00 The dynamics of combining the bubbles into one large and drying of the sample continues. |  |
Result:
When evaluating the interaction of the two above-mentioned environments, colonies collected in a chain were immediately identified. In sample №2, the chains were opened during observation, after the bubbles were combined, the voltage was reset and the sample showed a slight growth of bacteria only on day 6. In sample №4, the tension increased, but no growth was observed.
In a separate sample of the human biological environment in sample №1, growth was not shown, in sample №3, growth was observed on the 5th day of observation
Conclusion:
For the researcher, it is permissible to use raw melon in the diet.
