Evaluation of the ability to improve water quality of nitrogen-metabolizing bacteria in the rearing system of black tiger shrimp (Penaeus monodon) - 9

Bacterial density in treatments 2 and 3 was statistically significantly higher than treatment 1 and control from day 10 onwards, which showed that in treatments with added bacteria, the time for bacterial density increase was shortened. This also means that bacteria will quickly play a role in ...

Study on nitrogen-metabolizing bacteria in the bottom of the lobster farming area Panulirus sp. for aquaculture - 19

Figure 3.46 shows the experimental results showing that the density of nitrite-metabolizing bacteria (NOB) fluctuated from 10 2 CFU/mL – 10 5 CFU/mL after 30 days of shrimp farming. In the control treatment, NOB bacteria appeared at the 4th sampling time (13 days after farming), with a density of ...

Standard Nitrogen Solution (1Ml Contains 0.05 Mg N; Prepared As In The External Nitrogen Determination Section)

Nessler solution must have a certain alkalinity. Usually adjusted as follows: 11 - 11.5 ml of Nessler solution needs 20 ml of 1N HCl to neutralize (phenolphthalein color indicator). If quantifying N outside of protein, 1 ml of 50% H 2 SO 4 needs 9 - 9.3 ml of Nessler solution to neutralize. ...
