While the manned mission team was studying and observing these little lives from Mars.

At the same time, on the other side, the earth, Jinling.

Scientific researchers qualified to understand these Martian microorganisms are also busy analyzing the observation data sent back by the mission team.

In the laboratory, a middle-aged man in a white coat stared closely at the experimental analysis data in front of him, frowned for a while and then sighed.

"no!"

"These analytical data are far from enough! I suggest starting live sample cultivation and observation!"

Before he finished speaking, someone in the laboratory immediately retorted.

"Old Liu, are you crazy? Start living sample cultivation and observation, what should our astronauts do? That's on Mars, Mars!"

"If these Martian microorganisms are harmful to the human body and serious problems such as infection occur, will you be responsible?"

The middle-aged man named Lao Liu sighed and muttered: "But based on these alone, we cannot judge the harmfulness of these microorganisms at all, and it is even more difficult to judge whether they are harmful to the human body."

After hearing this, another old man with gray hair who was also wearing a white coat and refuted him sighed.

Indeed, even if they are professionals, they dare not make a judgment just based on the observation data sent back by the launch team.

For a life beyond the earth, the judgment methods and conditions are far more complicated than life on the earth.

On earth, if they want to study a microorganism, they have to use microscope observation, isolation and purification, physiological morphological identification, observation of in vivo culture characteristics, metabolic research, genetic research, etc., to figure out the characteristics of a microorganism and bacteria.

.

On distant Mars, most of these primary methods are almost unfeasible.

In particular, one of the most important experiments on the observation of in vivo culture characteristics is currently not allowed.

Because the fire landing team does not have the conditions to do it.

In order to ensure the safety of astronauts to the greatest extent, all experiments that require risky processing are not allowed.

In vivo culture characteristic observation experiments are undoubtedly a type with a high risk factor.

When carrying out the landing project, no one took the infection of alien microorganisms into consideration too much.

After all, neither the United States nor China’s previous exploration and research on Mars, or even their own unmanned exploration spacecraft, have found any signs of life on Mars.

Although there are relatively abundant water resources at the bottom of the Mariner Grand Canyon, the presence of water resources does not equate to the presence of life.

Therefore, the Hanhai manned mission team did not carry many instruments and equipment capable of conducting life experiments. Even the microscopes used for microscope observation were non-professional bioelectron microscopes.

But without in-vivo observation, they simply cannot judge the activity status, metabolic characteristics, genetic characteristics and other information of these Martian microorganisms based on the data observed by the mission team, or whether they have any impact on the human body.

It is also impossible to determine which drugs to use to possibly inhibit the spread of infection or treat it.

"It would be great if they could do a basic Gram stain test over there."

In the laboratory, a middle-aged doctor in a white coat put down the data report in his hand, pinched the bridge of his nose and sighed.

Gram staining test is a method to distinguish bacteria as Gram positive or negative through a series of steps (primary staining, mordant staining, destaining, and counterstaining).

This is the most basic and commonly used staining technique in microbiology.

Simply put, by slicing bacteria and microorganisms,

Gram stain can not only help us identify the type of bacteria, but also provide important information for subsequent research, such as antibiotic selection and disease diagnosis, etc.

But usually, Gram staining requires four different solutions: basic dye primary dye solution; mordant dye; decolorizing agent and counterstain solution.

This method divides bacteria, at least those on Earth, into Gram-positive bacteria and Gram-negative bacteria.

Both positive bacteria and negative bacteria have different basic drugs and treatments.

If they can identify it in a targeted manner, they can deliver corresponding drugs in the next supply of supplies.

Instead of being completely confused like now.

On the side, Professor Liu Shengrong from the Clinical Branch of the National Microbiological Science Data Center shook his head gently and said: "Gram staining is not necessarily useful for these microorganisms."

"Um?"

Upon hearing this, several experts in the field of microbiology and medicine in the laboratory looked over.

Pulling up a report picture, Professor Liu Shengrong pointed to the microorganisms on it and said: "Gram staining is for carbon-based life on earth. It is based on the identification of stored proteins."

"It is not certain whether these three microorganisms on Mars have protein structures."

After a slight pause, he pointed to the first microelectron microscope structure picture and matching elemental analysis experimental data in the report, and continued:

"At least this kind of microorganism is obviously very different from bacteria on the earth. If it is not mistaken, its surface structure is based on silicon."

"Considering the environment of Mars, combined with the location and environment of these microorganisms mined by the mission team, it is very likely that they are a type of silicon-based life that has never been seen before."

"Don't the microbial fossil remains we found in the caves at the south pole of the moon provide preliminary proof of this?"

"If they are silicon-based life, I am afraid that the current treatment options and drugs for carbon-based bacteria in our human medical technology will be ineffective."

On the side, Academician Zhang Hua from the Institute of Microbiology of the Chinese Academy of Sciences thought for a moment after hearing this and said: "If they are silicon-based life, maybe we don't have to worry so much."

"After all, silicon-based life and carbon-based life are two completely different types, and the probability of infection is still quite small."

This chapter is not over, please click on the next page to continue reading! "Just like viruses and microorganisms often find it difficult to infect each other between humans and animals, the gap between silicon-based life and carbon-based life must be bigger than this

."

"What I'm worried about...is that these life forms may be somewhere between carbon-based life and silicon-based life."

Upon hearing this, someone in the laboratory quickly asked: "A type similar to diatoms?"

Academician Zhang Hua nodded, with some worry on his face: "Since they are a kind of life, they naturally need to consider eating, the most basic conditions for the reproduction of these two kinds of life."

"Reproduction is not mentioned for the moment. If we eat, that is, 'survive', that is what we need to consider most at the moment."

"Considering the environment on Mars and the location where these microorganisms were excavated, from my personal point of view, these microorganisms most likely feed on carbon dioxide, underground water ice resources, and clay or certain types of substances in clay.

."

"After all, they always need energy to survive. It's impossible to reproduce without energy. This is unscientific."

"Considering the environments of Elysium Plains and Corinto Crater, I personally think that the greatest possibility is to use carbon dioxide as food, decomposing and converting it into methane, hydrogen acid and other waste products through specific enzymes and water ice resources."

"If it is this kind of life form, maybe human beings are a pretty good parasitic place for it."

"After all, humans produce a large amount of carbon dioxide and water vapor when they breathe. If the temperature is suitable for their reproduction, this means..."

He didn't finish what he said, but several people in the laboratory reacted.

The lively atmosphere suddenly quieted down, and there was no sound, and you could hear a pin drop.

It was clear to everyone present that if this set of seemingly reasonable inferences were true, then the human respiratory system would be the best place for these microorganisms to thrive and become infectious.

"Okay, okay, let's not scare ourselves first."

After a long silence, someone in the laboratory broke the strange silence and said with a dry smile: "These are all theoretical speculations. We still don't know what the actual situation is."

"It's also possible that this theory goes in the exact opposite direction?"

"After all, the several astronauts we have landed on Mars are still in good health, right? They have not been infected."

"This shows that at least in a short period of time, these microorganisms from Mars are not likely to infect the human body. Even if they are infected, the onset time will definitely be longer."

"In the intervening time, I believe we have enough time to understand their characteristics and conditions."

.......

At the same time, on the other side.

In the office of Xia Shu Space Base, Xu Chuan is also looking through the latest experimental data passed back by the mission team.

Opposite the sofa, Chang Huaxiang also held a piece of information in his hand. He frowned at it for a while and then asked, "What do you think these could be?"

Staring at the information in his hand, Xu Chuan replied without raising his head: "I don't know."

"have no idea?"

Opposite the sofa, Academician Chang Huaxiang's somewhat surprised voice came. Xu Chuan sighed, raised his head and looked over, shaking his head and saying.

"I am not God or the Creator. I don't know any more about the current situation on Mars than you do."

Standing in this new and unknown field, even if he is a top scholar, he is on the same starting line as everyone else.

The experience and time in the previous life will be completely useless here. After all, this is the first time that humans have come into contact with living creatures outside the earth.

What's more, he is not a microbiologist or biologist, and the useful information he can derive from these experimental data is not as good as those professionals in the laboratory.

They couldn't be sure, so how could he dare to say that he understood?

"Then do you think these microorganisms are silicon-based life or are they the same carbon-based life as on the earth?" Academician Chang Huaxiang asked.

After thinking for a while, Xu Chuan said: "I think they may be more similar to diatoms on the earth, between carbon-based life and silicon-based life?"

"Why do you say that?"

Xu Chuan shook his head and said, "Maybe it's an intuition."

Chang Huaxiang thought for a while and said: "If this is the case, they may cause infection or harm to our astronauts."

"After all, carbon-based microorganisms or bacteria in between are more infectious to humans than pure silicon-based life."
