Growing microbes on a large scale
- To make products like medicines or food on a big scale, microbes are grown in huge tanks.
- These tanks are called fermenters 发酵罐.
大规模培养微生物
- 为了大规模制造像药物或食物这样的产品,微生物在巨大的罐中培养。
- 这些罐叫做发酵罐(fermenters)。
Fermenter control loop · 发酵罐控制回路
Watch how a fermenter keeps microbes growing at the best rate. · 观察发酵罐如何保持微生物以最佳速率生长。
A fermenter is used to: · 发酵罐用于：
Fermenters culture microbes to make products. · 发酵罐培养微生物以生产产品。
What a fermenter is
- A fermenter is a large vessel that grows microbes under carefully controlled conditions.
- Everything is kept ideal so the microbes grow fast and make lots of product.
A fermenter grows microbes with the temperature, pH, oxygen and nutrients all controlled
发酵罐是什么
- 一个发酵罐是一个在仔细控制的条件下培养微生物的大容器。
- 一切都保持理想,所以微生物快速生长并制造大量产品。
一个发酵罐培养微生物,温度、pH、氧和营养素全都被控制
A water jacket around a fermenter is used to: · 发酵罐周围的水套用于：
It cools the tank to keep the optimum temperature. · 它冷却储罐以保持最适温度。
Which conditions are controlled in a fermenter? (Select all that apply.) · 发酵罐中控制了哪些条件？（选择所有适用项。）
Temperature, pH and oxygen matter; tank colour does not. · 温度、pH值和氧气很重要；储罐颜色无关紧要。
Controlling the conditions
- Temperature is controlled (a water jacket removes the heat from respiration).
- pH, oxygen (air is bubbled in), and nutrients are all kept at their best.
控制条件
- 温度被控制(一个水套移除来自呼吸作用的热量)。
- pH、氧(空气被鼓入)和营养素全都保持在它们的最佳状态。
A fermenter is kept sterile to stop other microbes contaminating the product. · 发酵罐保持无菌状态，以防止其他微生物污染产品。
Sterile conditions prevent competition and contamination. · 无菌条件可防止竞争和污染。
A ______ keeps the contents of a fermenter mixed and evenly supplied. · ______用于混合发酵罐内容物并确保均匀供给。
Stirring distributes heat, oxygen and nutrients. · 搅拌可分散热量、氧气和营养物质。
Keeping it sterile 无菌的
- The fermenter is kept sterile (free of other microbes) so nothing competes or contaminates the product.
- A stirrer 搅拌器 keeps everything mixed and evenly supplied.
Fermenters must remove heat, not add it. Microbes respire and release heat; if the tank overheats, enzymes denature and the microbes die. A cooling water jacket keeps the temperature at the optimum.
保持无菌
- 发酵罐保持无菌(sterile,没有其他微生物),这样没有东西竞争或污染产品。
- 一个搅拌器(stirrer)保持一切混合并均匀供应。
发酵罐必须移除热量,而不是添加它。 微生物进行呼吸作用并释放热量;如果罐过热,酶变性,微生物死亡。一个冷却水套把温度保持在最适值。
You've got it
- a fermenter grows microbes in large amounts under controlled conditions
- temperature, pH, oxygen and nutrients are all kept ideal (a water jacket cools it)
- it is kept sterile and stirred to maximise product and avoid contamination
你掌握了
- 一个发酵罐在控制的条件下大量培养微生物
- 温度、pH、氧和营养素全都保持理想(一个水套冷却它)
- 它保持无菌和搅拌,以最大化产品并避免污染
