Latest website: The test tube tilted slowly, and the light yellow liquid contained in the test tube stretched into a thin, translucent line, and landed on the mineral water bottle lying flat.

In the first few seconds after I sprinkled it on, I couldn’t tell what it was about. After a few breaths, some very small bubbles began to appear in the solution attached to the outer wall of the bottle. The solution that originally looked clear and transparent began to become turbid, and the color it appeared gradually deepened from the previous light yellow to a deep yellow.

After a while, the bacteria, which were completely stimulated, began their first round of division and proliferation.

Just like a half-grown boy who can eat a poor man, after splitting into two separate individuals, the growing cells will show a more vigorous appetite. In addition, the quantity has doubled, and the 'eating capacity' will also double from the original basis...

The speed at which the solution engulfed the walls of the plastic bottle suddenly increased a lot.

In just over two minutes, small holes had been dug out of the originally intact bottle, and the mineral water in the bottle also flowed out along these small holes.

"So, this efficiency is not bad." He had been paying attention to Namor's expression changes, and seeing his surprised look, Stark once again showed a proud smile.

"It's incredible, faster than I thought." His tone was full of emotion. Namor looked up at Stark and gave him a thumbs up with admiration: "He is indeed the world's number one genius. Mr. Stark, this invention of yours is really amazing. It opened my eyes today and it’s so worth it.”

While Namor was praising him, the dissolving speed of the plastic bottle suddenly slowed down a lot.

Seeing this scene, the female Sea Tribe standing next to her frowned unconsciously and let out a soft hum filled with confusion.

"This is because the water in the bottle flows out, which reduces the concentration of microorganisms many times." Without asking, Stark just glanced at the sink formed by the dent on the table and immediately guessed what the other party was thinking: "As the concentration decreases, the devouring speed will naturally decrease. But don't worry, after they split a few more times, the speed will increase again, and recovery... no, it should be faster than before."

"Can it be faster?" Namor was surprised again.

"Yes, under my preparation, this kind of bacteria can divide for a total of five rounds, which means that their final number will reach 32 times the original number." At this point, Stark raised his hand and pointed. The test tube in Namor's hand: "More than half of the original solution in this tube is culture fluid, and the concentration of microorganisms is only about 40%. In other words, in twenty milliliters of solution, there are only about 8 milliliters of microorganisms in total. ”

"Next, just do a little calculation and you can draw a conclusion. After five divisions, the total amount of bacteria is almost 250 ml... In other words, in the final total of more than 500 to less than 600 ml of solution, "Bacteria make up almost half of it, which is slightly higher than when it's in the test tube."

"Of course, this is just a result calculated based on theory, and has no reference value. After all... there is only one plastic bottle here, and the little 'nutrients' it has are simply not enough to feed so many bacteria. Chapter Second generation? Or third generation? Anyway, these bacteria will definitely disappear without a trace."

The lower the concentration, the worse the efficiency. This is easy to understand.

Instead of continuing to dwell on this point, Namor was more concerned about another question: "What if... the bottle is not filled with mineral water, but seawater with a higher salt content? This kind of bacteria can adapt to such a high salt content, in seawater Will you survive?"

"You're on to the point of your question." Stark raised his eyebrows proudly: "In fact, the reason why I developed this bacteria is to clean up plastic waste in the sea. In other words, From the beginning, I set the direction and deliberately cultivated it into a type that can perfectly adapt to the seawater environment. "

"...In other words, in seawater, can it digest plastic faster?" Namor asked with anticipation in his eyes.

"It can probably be improved by about ten percent." Nodding, Stark replied with a smile: "Of course, compared with now, it will definitely be many times slower. After all, this is a closed water tank, and all the added value will come out All the bacteria will be concentrated together, but in the ocean, there is no such boundary, so... can you understand what I say? "

"It will continue to spread with the flow of sea water, and it won't stay in the distance forever, right? It's not difficult to understand. I think I should understand."

"Yes, that's what I mean." Stark nodded and continued: "Although it won't stay in a certain place forever, as long as new bacteria are added periodically at a certain frequency, the cleaning efficiency is still guaranteed. of."

Hearing this, Shi Xiaolei also joined in the fun and chimed in with an idea: "I think it would be a good idea to use it as an 'air freshener'."

Large pieces of plastic waste may take some time to process, but those plastic particles wrapped in seawater that are so small that they are difficult to detect with the naked eye may only take a moment.

Just spray it and it will filter out a small amount of sea water. Isn't this feeling just like the freshener used to deal with abnormal smells in the air?

"Locke is right, this is indeed a pretty good use." Nodding, Stark agreed: "When you leave, you can take some back to try. Although I don't know what the house you built underwater is. What does it look like, but I think each one should have its own room. If you close the door tightly and let it blend into the room... Haha, believe me, you will be able to feel the change in water quality in a short time. ”

"It sounds pretty good, but..." Looking at Stark, Namor asked hesitantly: "This thing shouldn't be toxic, right? If you inhale seawater containing this kind of bacteria, it will endanger your health. "?"

"Well..." After scratching his head, Stark smiled slightly awkwardly: "I can only confirm now that it is harmless to humans and will not harm other marine life. As for you... maybe I have to do several experiments before I can draw a conclusion. After all, I haven't collected any data yet, so I don't know how different you are from ordinary people."

"You mean... we must cooperate with you to complete the experiment to determine whether it will harm our health?"

"Yes, if you want to ensure safety, it is an indispensable part." Noticing the change in Namor's expression, and remembering what Shi Xiaolei said when introducing the origin of the Sea Tribe, Stark quickly added two more Sentence: "Of course, the experiments I mentioned were all conducted under the premise of ensuring 100% safety. I promise that the scene hundreds of years ago will never be repeated."

The tone was firm, but in the final analysis, it was just a verbal assurance.

Having personally experienced the Spanish invasion and watching many tribesmen die due to the virus brought by the Spanish, from Namor's perspective, it was of course impossible to make a decision based on Stark's guarantee alone.

"...Give me some time, I have to calm down and think about it."
