National Beer

The color TV, washing machine, and refrigerator were all available. Sitting on the modular sofa, Wu Geng deliberately raised his hips and sat down again. The sofa trembled and was extremely comfortable.

"Hey, it's still a two-cylinder washing machine...rich man, rich man," Wu Geng smelled the scent in the air. He got up and walked out of the main house. Xidaiquan was used as a kitchen. Oh, the scent came from inside.

"Is there still a bath here?" Wu Geng pushed open a wooden door to the south. There were white tiles on it, and there were white sprinklers on the wall. As soon as he turned the switch, water spouted from the sprinklers.

"I will enjoy it. You don't need to take a bath in the big bathhouse, you can wash at home." Wu Geng rarely gave a thumbs up, "Oh, Xiaoju is back."

"Hello, Mr. Wu." Du Xiaoju smiled. She and Wu Geng have known each other for more than two years. "The Sophora japonica has bloomed. Dadong said that you should come home to eat steamed Sophora japonica, as well as Sophora japonica ribs bun... …" She raised the vinegar in her hand, "The buns will be out of the pot right away. I just bought a bottle of vinegar."

"Then, I will trouble you." Wu Geng shouted with a smile. He picked up the textbook on the sofa. The Municipal Second Light Bureau system opened a TV junior class this year, and Du Xiaoju passed the entrance examination. "Oh, congratulations. , They are all college students."

Wu Geng picked up the chopsticks and gently picked it up, and the bottle cap flew up with a sound.Qin Dong still used his teeth. He bit the bottle cap and spit out the bottle cap smoothly. The two of them touched the bottle and drank half of each.

Wu Geng was not too hot. He picked up the steamed buns and took a bite. "Well, it's delicious." He pushed his glasses and smiled, "Isn't it the one who specifically asked me to eat the steamed buns? Now the whole city is talking about turtles and turtles. , Let's talk about it, what do you want to do?"

"The key to making new beer is yeast." Qin Dongdao, "Different factories use different yeast strains and use different process conditions. Most of our country's breweries use fixed yeast, which can ferment glucose, maltose, and galactose. , Sucrose, melibiose and raffinose, but there are differences in process performance. Therefore, the beer of each factory has different flavors. Although we are an affiliate of Qin Beer, the taste of Rong Beer and Qin Beer is different.

"Then what kind of yeast do you want to choose?" Wu Geng took Qin Dong's cigarette and lit it himself.

"I want to use different types of yeast to cross, separate and breed, and finally look at the changes in diacetyl during fermentation, compare the yeast’s ability to form and reduce diacetyl, and see which of the hybrid yeast strains can be tested in production. Diacetyl dropped from 0.12 ppm to less than 0.5 ppm, and the bitterness value of wine dropped from 22 to 20 to 18 to 15..."

"This can remove the horse urine taste of beer." Wu Geng understood. "Different yeasts have different tastes for beer. What we want is light and refreshing, so we must cultivate such yeast..."

He suddenly pointed to Qin Dong and smiled, "Okay, I understand what you mean, you want to use the yeast from the main factory, and then use the yeast from Qin Beer, and the yeast from Haicheng and Baisha?"

"Worthy of being Director Wu..."

"You don't have to praise me..."

"Yes, I just want to select a variety of yeasts for hybridization, and the laboratory conditions of our main factory can't reach..."

"Then use Qin Beer's laboratory," Wu Geng stood up and said immediately, "I pulled the top Ling Xian, he is our deputy technical director, or is the deputy chief of the technical department of Qin Beer, they have good conditions. , Your kid, this turtle must turn that turtle over for me..."

...

What Qin Dong didn’t expect was that Chen Shifa and Zhou Fenghe would also go to Qin Beer together when they heard about it. The laboratory was divided into an experimental studio and a sterile room, sterilization kettle, electric oven, incubator, microscope, and refrigerator. Ultra-clean workbench, unconditional inoculation box... These equipments are the most advanced in China.

"Our joint factory is not called for nothing, and the usage fee for a bottle of four cents is not for nothing. At the critical moment, Qin Beer can do whatever it takes." The car was filled with the directors of Rong Beer. , Chen Shifa joked.

"uncle?"

Zhou Yi didn't see Zhou Fenghe. She first saw Qin Dong, who was walking violently, and she subconsciously shouted the word. Qin Dong laughed when she saw her.

The little girl was wearing a white lab coat, but she was too short, and she wore a white lab coat like a Taoist robe.

However, Zhou Yi's eyes widened. Behind Qin Dong, Chen Shifa, Zhou Fenghe...all the factory directors came, as did the labor union chairman and the party branch secretary.

gang war?

Zhou Yi suddenly thought of three words.

The director of Qin Beer quickly received the report. He didn't know what had happened. Since it was a joint venture, the leadership team of the other people had come. He also hurried back from the city as if he was facing a big enemy, and called immediately. The factory leadership at home.

Ugh!

The guest and host were seated. When he heard the intention of the other party, the director of Qin Brewery was relieved, "What am I doing? Yes, of course it can be used. We can provide yeast or a laboratory." He looked at Qin Dong. Now the whole city knows about the dispute between turtles and turtles.

This year, the country has set off an upsurge of going abroad. The US Consulate General is crowded with people. Everyone has an infinite yearning for foreign countries, and even those who have returned from abroad.

He is not optimistic about Qin Dong. In fact, when he came to the city today, he wanted to invite Dong Qingkun to the factory. It is true that as Mayor Guo Peng said, he would come to serve as deputy chief engineer.

However, Dong Qingkun returned to Shennan after staying in Qinwan for two days. Before leaving, he made a call to the telephone exchange. He spoke German and the driver couldn’t understand it. He contacted the teacher at the Dumins Beer Academy and planned to travel from Germany. Introduce beer yeast with high fermentation degree.

Introducing is one aspect. After he returns to Shen Nan, he has to cultivate by himself. If he does both, he doesn't believe that he can't defeat Qin Dong!

Qin Dong was not idle either. That night, yeast from Qin Beer, Rong Beer, Haicheng, Baisha, and Arctic Ocean were all transported to the Qin Beer Laboratory.

Cui Wei also followed Yeast to Qinwan. Like Zhou Yi, she served as Qin Dong's assistant.

"We have isolated and selected five strains of beer yeast from different sources, numbered Beihai No. 1, and Beihai No. 2..." Qin Dong, wearing a white coat, pointed to the seed pot on the table.

Fang Lingxian, deputy technical director of Rong Brewery, and Luo Yuhui, deputy chief engineer of Qin Brewery, also came to the scene. They did not say a word, listening to Qin Dong's arrangement.

"The medium and reagents I need...

One is the wort liquid medium, I need 11 to 12 degrees wort.

The second is the basic medium for sugar fermentation. I need 4.5 grams of yeast extract, 7.5 grams of peptone, and 1,000 ml of distilled water..."

...

Seven is the spore dye solution, I need malachite green and saffron..."

Just like in Shennan, Cui Wei kept recording, and Zhou Yi's small head kept moving through the laboratory.

"Inoculate the strains in a wort liquid medium, and after three days of cultivation at 25 degrees, take the culture medium for microscopic examination and measure the cell size...

"Shake the above-mentioned fermentation broth evenly, plant it on a wort agar plate, and incubate at 25 degrees for about a month..."

The two nodded, indicating that they had all written down.

"Well, it's interesting." Luo Yuhui looked at Qin Dong's steps, "Lao Fang, let's have a look tomorrow night?"
