Chapter 1227

It has not been a short time since the completion of the lunar scientific research station. The number of people living on the moon has almost doubled in a year, and now it has grown to more than 50.

However, this population growth is not unlimited.

From this year on, the lunar orbit Construction Committee announced that it would limit the increase of the number of permanent residents on the lunar surface in a short period of time, and requested the management unit to control the number of permanent residents of the lunar surface scientific research station as much as possible to less than 60 under the premise of maintaining the current scientific research plan and the lunar resource development plan unchanged.

The reason for such an arrangement is not that the cost of maintaining an astronaut's life in space is too high as people think, but that the actual conditions do not allow it.

Just like the health problems faced by many megacities, the population scale of the monthly scientific research station is far from the level of the city, but because there is no ecosystem that can be naturally degraded, the difficulty of solving the health problems is magnified exponentially with the population growth.

According to the needs of an adult's normal life, the domestic waste produced in a day is about 1kg, of which the metabolic waste accounts for more than 50%. However, for these metabolic waste, the moon science station is almost unable to completely dispose of it.

Even though the lunar planting unit can consume a part of feces and urine and let organic matter enter the circulation again, the circulation efficiency is not so high.

Combined with some bacteria and microorganism pollution, health and safety has become a problem that can not be ignored in the monthly scientific research station. Just to transport those living wastes back to the earth, it has already occupied the capacity resources of a whole transport ship.

If the size of the population continues to expand, I'm afraid that the moon orbit construction committee will have to specially plan a special route for transporting excrement and urine.

However, the emergence of dr-111 active microorganism has brought a turning point for everything.

No one knows where it came from, and the project appears in the database as if it were suddenly assigned personnel for research one day.

Although some people have been curious about which big cow it is and where such a powerful microbial sample has been collected, due to the lack of literature, it is not known.

Drinking coffee, looking at the data fed back from the lunar science station on the screen, Lu Zhou's face showed such an expression.

As he guessed, this dr-111 microorganism is not so simple.

In aerobic environment, it decomposes metabolites through respiration, and at the same time, it also accumulates a kind of ketone substance. In fact, although this kind of ketone substance is harmless to other organisms, it is harmful to itself.

Long time exposure to aerobic environment will lead to the slow reproduction of the whole microbial community, and eventually self destruction.

But on the contrary, if it is in high nitrogen, carbon dioxide concentration, and light environment, the microorganism will produce amazing reproductive capacity and eating ability.

It not only consumes and decomposes metabolites, but also generates oxygen through photosynthesis, which fixes solar energy in a special chain of amino acids.

Although the taste of direct consumption may not be so ideal, this special amino acid molecular chain can be digested by the vast majority of organisms, that is to say, it can directly enter the ecosystem cycle.

Not only that, this kind of creature has extraordinary tolerance to low gravity environment, and even under the direct irradiation of cosmic rays, it can maintain the stability of the overall character by decomposing and phagocytizing its own cancer cells.

It's a great waste purifier!

Using it on earth is just a stooge. Space station and space colony are the real places it should go.

Seeing the experiment report from the beginning to the end, the expression on the face of the boat became more and more satisfied. Then just then, a flash of light - or a hole in the brain - flashed through his mind.

"Would this be some kind of man-made atmospheric modification material?"

A civilization that entered the interstellar age created it, and then planted it on the chaotic planet that just formed the atmosphere, to colonize its own civilization.

This kind of interesting microbe will be in the atmosphere with high carbon dioxide concentration and grow exponentially, even covering the whole planet's surface.

Finally, in countless stellar years, it plays the role of both producer and decomposer, absorbs excessive carbon dioxide and releases oxygen, accelerates the process of atmospheric evolution, and allows more carbon elements to be fixed into organic matter that can be directly used by organisms through photosynthesis, and enter the biosphere cycle.

At the last stage, with the increasing of oxygen, photosynthesis gradually becomes respiration, and the generated ketones begin to kill the micro organism and make it lose the ability of reproduction until it completely disappears from the whole ecosystem.

After all these tasks are completed, a chaotic planet covered with carbon dioxide may be able to complete the atmospheric evolution process that originally took hundreds of millions of years in only a few decades.As soon as the brain hole opened, it couldn't stop. The more the boat thought about it, the more likely it was.

After all, there are too few planets in the universe that are suitable for carbon based organisms, and oxidation is the way for most organisms to obtain energy.

Under the condition of natural evolution, it may take hundreds of millions of years for a chaotic planet filled with carbon dioxide and nitrogen to become a relatively Livable World with rich species.

If a civilization develops to the level of interstellar civilization, and can expand its territory to areas within hundreds of light-years by means of superluminal speed, it is not impossible to master the planetary transformation technology.

Even, it is almost inevitable.

After all, the nature of civilization is the transformation of nature.

Only the beast will choose to be obedient.

"I didn't expect to find such a wonderful thing..."

Shocked by his own ideas, Lu Zhou's pupils gradually became excited.

If his idea is true, the microbe in his hands at this moment will not be just a simple "space version of waste purifier", but a living fossil from a higher civilization!

What is worth studying is not only the microorganism itself, but also the biotechnology and gene modification technology it may contain.

It is not clear how much can be reversed from it, but even if there is only a little harvest, the help will be huge for human civilization in the early space age.

In addition, the land boat also thought of Mars near by.

It's not realistic to directly transform the atmosphere of Mars. After all, the gravity of Mars is too small and there is no magnetic field protection. Even if an atmosphere similar to the earth is created, most of it will be lost eventually.

But if we build a relatively closed large biosphere in a limited area, the feasibility is quite great.

With the environmental transformation ability of this microorganism, as long as the method and transformation plan are appropriate, it may not be a problem to create such a closed biosphere on Mars.

Thinking of this, somehow, Lu Zhou suddenly thought of what the observer and himself said, and a little thought of terror rose in his mind.

It's impossible that everything is the best arrangement.

But maybe

This solar system may have been "designed" well
