Fermenter vs Bioreactor: What’s the Difference

If you’re in the biotechnology industry or beer brewing industy, you may have come across the terms fermenter and bioreactor. But what do they mean and how are they different? In this article, we will explain the definitions, functions, and differences of fermenter and bioreactor.

What is a fermenter?

A fermenter is a device that facilitates fermentation, which is a metabolic process that converts sugars into acids, gases, or alcohol. Fermentation usually occurs under anaerobic conditions (without oxygen) and involves microorganisms, such as bacteria, yeasts, or fungi. Fermenters are used for various applications, such as producing ethanol, lactic acid, cheese, yogurt, bread, beer, wine, etc.

A fermenter is a type of bioreactor, which means it is a system that supports biochemical reactions involving living organisms or their products. A fermenter typically consists of a vessel that contains the medium (such as water, nutrients, and sugars) and the microorganisms. The vessel is equipped with features that control the temperature, pH, oxygen level, agitation, and aeration of the culture. The vessel also has ports for sampling, inoculation, harvesting, and cleaning.

At Plygen Industries, we offer a wide range of high-quality stainless steel fermenters for various industries, including Beer fermentation tanks. Our fermenters are designed and manufactured to optimize fermentation performance and efficiency. They can be equipped with features such as cooling jackets, pressure relief valves, sampling ports, etc. to ensure proper temperature control, safety, and quality control during fermentation.

What is a bioreactor?

A bioreactor is a device that enables various types of biochemical reactions involving living organisms or their products. Bioreactors can be used for different purposes, such as producing pharmaceuticals (such as vaccines or antibodies), biofuels (such as biodiesel or bioethanol), food additives (such as enzymes or vitamins), chemicals (such as organic acids or alcohols), etc. A bioreactor can use different types of cells or microorganisms such as plant cells, animal cells, stem cells, bacteria, yeasts, fungi, algae, etc. Bioreactors can also use different types of biochemical reactions, such as fermentation (as mentioned above), photosynthesis (which converts light energy into chemical energy), cell culture (which grows cells in an artificial environment), etc.

A bioreactor typically consists of a vessel that contains the medium (such as water, nutrients, and substrates) and the cells or microorganisms. The vessel is equipped with features that control the temperature, pH, oxygen level, agitation, and aeration of the culture. The vessel also has ports for sampling, inoculation, harvesting, and cleaning.

Fermenter vs Bioreactor: What’s the Difference and Why Does It Matter?

As you can see, fermenter and bioreactor are two terms that describe similar but not identical devices. The main difference between them is the type of biochemical reaction they facilitate. A fermenter is used for fermentation only, while a bioreactor can be used for various types of biochemical reactions. Therefore, a fermenter is a kind of bioreactor, but not all bioreactors are fermenters.

The difference between Bioreactors and Fermentors matters because it affects the type of products you can produce and the type of equipment you need. Depending on your application and industry, you may need a fermenter or a bioreactor or both. For example, if you want to produce ethanol from sugar cane, you need a fermenter. If you want to produce biodiesel from algae, you need a bioreactor.

At Plygen Industries, we can help you choose the right equipment for your cultivation needs. We have extensive experience and expertise in designing and manufacturing fermenters and bioreactors for various industries and applications. We can also customize our equipment according to your specifications and preferences.
