What is ‘Upstream Bioprocessing’?

Upstream Bioprocessing is, as the name suggests, the early stages of bioprocessing. If your Bioprocess was a mighty river – it would spring into life (sciences) up in the peaks of mount Bacteria and travel down through mysterious lands such as The Kingdom of Cultivation and The Fields of Fermentation to eventually wash out into the great Ocean of Pharmaceuticals.

But, enough of this watery metaphor. Let’s use some proper scientific terminology.

Of course, in order to clearly understand the babble of technical jargon that defines our industry, we must first define what the term ‘bioprocessing’ actually means:

Bioprocessing simply describes a process that obtains living cells or components from microorganisms such as enzymes, chloroplasts or bacteria, to manufacture pharmaceuticals, vaccines, diagnostic agents, industrial enzymes or chemicals.

It is a multidisciplinary field that combines the principles of biology, chemistry, and engineering to design, develop, and optimise processes for the production of these products. 

‘Cell Bioprocessing’ is the umbrella term that includes the two stages of bioprocessing: ‘Upstream Bioprocessing’ and ‘Downstream Bioprocessing’.

Upstream Bioprocessing refers to the initial stages of producing biological products, such as cell culture, fermentation, and purification. They are typically done on a large scale and are focused on maximising cell growth and product yield.

Downstream Bioprocessing (which we’ll come to in a different blog) refers to the later stages of producing biological products, such as purification, concentration, formulation, and packaging. These processes are often done at a smaller scale than Upstream.

So, let’s start, like that mighty river, with Upstream Bioprocessing

Upstream Bioprocessing:

The phrase ‘Upstream Bioprocessing’ describes the early stages of the bioprocess. This is where microbes, cells and bacteria are grown, nurtured and developed through a range of technologies and media.

In detail, those stages are:

1: Cell Isolation 

This is the process of separating a specific type of cell from a mixture of cells. Cell isolation is an important step in bioprocessing, as it allows for the cultivation of pure populations of cells.

2: Cultivation 

This refers to the growth of cells in a controlled environment such as a bioreactor. This can be done in batch culture, where cells are grown in a single container, or in a continuous culture, where cells are grown in a steady-state system. The goal is to achieve optimal growth conditions for the cells in order to maximise production.

3: Cell Banking 

This is the process of storing cells for later use. The cells are typically frozen in liquid nitrogen or preserved in a cryopreservative. Cell banking allows for a supply of cells to be preserved, ready to be used on demand. It removes the need to create an entire upstream bioprocess workflow every time they are wanted.

4: Culture Expansion 

This is a way of increasing the number of cells in a culture, through techniques such as cell splitting. This increases the yield of cells that are available for downstream processing.

Okay, so what happens now?

After the Upstream Bioprocessing stage, the media will go on to the next stage of its product development journey, known as Fermentation …

ALLpaQ What is Upstream Bioprocessing

Fermentation

We have discussed in the past how important fermentation proved to be to the evolution of the life sciences.

Well, it continues to be a major part of bioprocessing. Fermentation is a purification process that uses microorganisms such as bacteria or yeast to convert a substrate (such as sugars, starches, or organic acids) into useful products.

Fermentation can be used in the production of a wide range of products and media, such as enzymes, antibiotics, hormones, and proteins.

The goal of fermentation is to achieve optimal growth conditions for the microorganisms, and to maximise the production of the desired product.

Additionally, fermentation can also be applied to produce secondary metabolites like antibiotics, pigments, and flavours. The process is commonly used in the industrial production of biofuels, food, beverages and, of course, biopharmaceuticals.
