"Ethylene glycol phthalate, commonly known as polyester resin. According to the understanding of ordinary people, it is a kind of plastic."

"In the classification of plastics, the code name of PET is No. 1, and it has a wide range of functions."

"It can make various electronic and electrical items, such as sockets, electronic connectors, rice cooker handles, TV deflection yokes, terminal blocks, and breaker housings, switches, motor fan housings, instrument mechanical parts, currency counter parts, electric irons , accessories for induction cooker ovens.”

"In automobile manufacturing related industries, PET can be used to make flow control valves, carburetor caps, window controllers, pedal transmissions, switchboard covers; mechanical industry gears, blades, pulleys, pump parts, and wheelchairs. bodies and wheels, lamp housings, illuminator housings, drain fittings, zippers, clock parts, sprayer parts."

"For ordinary people, the most common PET products should be various plastic beverage bottles, as well as various polyester cloth and textile products made after drawing them into fibers."

Hearing Stark's order, Jarvis immediately took over and explained it to Shi Xiaolei in great detail.

Unlike Stark who put a lot of proper nouns in his words, when giving examples, he also mentioned some things that Shi Xiaolei often sees in his daily life. There is one thing to say, Jarvis's explanation is really simple, and it is much easier to understand.

"For a long time, it turns out that it is plastic for beverage bottles~." Suddenly realizing, Shi Xiaolei raised his hand: "Thanks, Shi Lianghong."

"It's polite, and I'm happy to serve him."

After saying that sentence, Shi Lianghong became silent again.

In addition, Stark's question just hit the key point, and it seemed to have scratched Jarvis' itch...

"Using this bacterium as a prototype, you carried out targeted cultivation and debugging. So far, you have developed a total of 18 new types of bacteria, and the worst effect is sample No. 4, which is not what he is currently. The 'Mister Weak One' you saw."

"There is a mistake." With a smug expression again, Jarvis regained his spirits and finished introducing Stark: "The prototype of that bacterium is a species called Sakazakiella... er, forget it, He also understands what he said. In short, it is not a kind of bacteria that was born in the natural environment and cannot swallow plastic by nature."

Whether it is poisonous or not, it can only reproduce for seven generations, and it will automatically decompose before the lifespan is exhausted...

"Of course there is a problem." Shi Lianghong replied in a stern manner: "He can think of that, can you think of it? Besides, did you say it just now, whether it is the 'sea surface' or 'Undersea'~!"

"Needless to say~." With another burst of complacency, Jarvis replied confidently: "You have tested them dozens of times, and they are just like other harmful single-celled organisms. Toxicity. He was also entirely concerned that they would break the existing marine life chain."

"Is it going to have any negative impact on marine life if it is released overseas? Although there is no culture, you have also heard of the so-called marine life chain, and you know that there is no very important link called plankton. You It means...if those things are thrown into the small sea, they should not be plankton in the downstream of the biological chain, right? If the plankton eats that kind of bacteria, will they be stimulated to cause any changes? Think further A little bit, shrimps eat plankton, big fish eat shrimps, small fish eat big fish, then put them on one by one..." Shrugging, Stark twitched his mouth: "Dude, he knows what you're worried about, Right?"

"Please remove the 'title', thank you." With her arms folded behind her chest, Shi Lianghong straightened her back triumphantly, with an embarrassing expression on her face.

"Um, it's bad, you are careful." Nodding, Stark asked again: "What about the other way around?"

Taking advantage of Shi Xiaolei's time to explain Stark's doubts, Jarvis hurriedly calmed down the depression in his heart. At that time, my mood recovered and recovered.

"And the lifespan of that bacterium itself is not the survival time of each bacterium, it's about 81 hours. Combining with the 'minimum of seven generations of united reproduction' you just said, a little calculation, um...bad It’s not that the effect lasts for a day or less before each active release. But before that, they will die by themselves.”

"In turn, what do you mean?" Looking at Stark, Jarvis blinked, showing a look of understanding.

"As a prototype, the Sakazakii bacteria must be able to show vitality in an environment of 30°C and decompose PET films. In addition, it takes about eight weeks to completely decompose and completely transform PET materials into Hazardous substances. From your point of view, Sakazakiella is not meaningful in terms of environmental requirements or decomposition efficiency."

That's right, maybe it's become a habit to argue with Jarvis, Stark still couldn't help interrupting my speech, and asked hesitantly: "Can that thing adapt to seawater? You mean... outside the seawater Will the salt content in the sap be so small that it will reduce its activity?"

"And the 'Mr. Weakness No. 1' you bred has the shortcomings just mentioned. First of all, it can only adapt to high temperatures above 10 degrees Celsius, and its low temperature resistance has reached 45 degrees Celsius." ℃ right and left. It doesn’t mean that it can’t survive under the sea surface under direct sunlight~lightnovelpub.net~ or in the completely white seabed, and it’s showing its abilities at a discount. "

The more he listened, the more he felt humbled. Stark had to show a look of admiration, and gave Shi Lianghong a little thumbs up: "He is still awesome, and he is worthy of being the number one genius in the world."

It sounds really awesome, even Stark, who is a doorman, can't help but feel admiration.

"Looking at his expression, he hasn't delayed thinking about it yet?" Stark asked along the way.

Stark, on the other hand, turned his gaze back to his bad friend, and pointed at the translucent screen again: "Dude, what did he just say? That kind of bacteria is specialized in eating PET?"

"It's just that, when you were retrofitting and debugging, you also deliberately used the Rixing technology he brought back, and put a 'gene lock' on it. But in the water environment, because the oxygen content is sufficient That’s why, it can only unite and reproduce for at least seven generations. It doesn’t mean that even if it is left unattended, it can also reproduce endlessly, and it can be everywhere.”

"Including its decomposition efficiency, it has also been reduced by several orders of magnitude, reaching less than 100 times the original efficiency. It is not to say that it takes eight weeks for Sakazakiella to decompose the PET material. If Mister Weakness No. 1 is to deal with it, it can be done in at least 10 hours."

"To be more specific. It is certain that those bacteria have not been eaten by plankton, they will die naturally before their lifespan is exhausted, and then decompose into the most basic inorganic substances by themselves before a period of time. He completely It is because we are worried that we will always be floating in the sea, and then gather less and less, and because the number is too small, it will become another source of pollution in a practical sense.”

"So that's what he was talking about. Hehe, of course you understand."
