Probiotic strains

Probiotics – mighty little helpers at your service

Do you want to develop new microbial strains for your portfolio? Or improve the properties of your established product? With our proprietary collection of probiotic strains and a broad portfolio of technologies, we are your partner for evidence-based development of probiotic products for various applications and markets.

Probiotics (Latin “for life”) are living microorganisms having a health-promoting effect on humans and animals. The focus is primarily on intestinal health, which is why probiotics have been used in the food sector for over 50 years (so-called functional food). A few years ago, other applications were discovered: e.g. in cosmetics, in agriculture or in the household sector.

Not every probiotic strain is suitable for every application. In addition to bioactive efficacy, probiotics must meet certain stability criteria to be marketable for use in products. Here, spore formers often have an advantage: spores are extremely heat resistant and tolerate extreme pH values, high pressure and the presence of organic solvents. Spores are stable over the long term and reach their complete vitality after germination.

What pro- or postbiotics can do for your products

Innovative application options

Innovative application options

Probiotics are already contained in household products such as cleaning agents and air purifiers. They are also used in textiles and foams. They combat odors, support surface cleaning, prevent unwanted microbial growth, purify the air and impart other positive properties to the environment. Or let’s imagine further innovative applications, such as probiotics in paints.

Plant protection

Plant protection

In the agricultural sector, probiotics play a role primarily in biostimulation of growth, plant resilience, seed protection, micro- and macro-nutrition of the young plant, and nitrogen fixation in the root zone. The future market of "vertical farming" could also benefit from the use of probiotics.

Health and well-being

Health and well-being

Probiotics are widely used in the field of health, e.g. to promote intestinal health, for weight management, to control individual cholesterol levels, to strengthen the immune system, for mental fitness and concentration or for therapeutic support of irritable bowel syndrome.

Healthy and nutritious pet food

Healthy and nutritious pet food

Probiotics support the intestinal flora of farm animals and pets and protect them from pathogenic microorganisms. In this way, they actively improve the intestinal health of animals. With their secreted enzymes, probiotics also improve the animals' feed digestion and the absorption of the nutrients contained therein. Due to the improved nutrient absorption, the animals' immune system is strengthened, which in turn protects against pathogens and improves overall animal welfare.

Innovative cosmetics

Innovative cosmetics

In the cosmetics industry, so-called postbiotic products with valuable ingredients in the form of killed microorganisms or microbial extracts are used. Postbiotics strengthen the individual skin microbiome, which in turn serves to care for and regenerate the skin and prevents premature skin aging.

Our resources and skills

Pre-characterized microbial strains

We have a set of selected and pre-characterized microbial strains. These are stable, safe and producible. Together with our partners, we are ready to further develop these strains into a probiotic product for customers – for a wide variety of applications and a wide variety of markets.

Our strain collection

Modular technology portfolio

For further characterization, evaluation of performance for specific applications, optimization of properties and development of our own strains as well as customer strains, we offer – in addition to our broad microbiological and molecular biological expertise – our established technology platforms.

Our technology portfolio

Our offer – your benefit:

From concept to product

BRAINstorming for the concept

Our concept is tailored to your field of application, as well as to the desired dosage form, taking into account the regulatory framework.

Find strains

Finding the right strain – where to start?

  1. Select a probiotic strain from the BRAIN set
  2. Perform targeted isolation from different habitats
  3. Further develop one of your own strains

The choice is yours.

Screening & characterization

In-vitro assays that reflect natural habitat conditions provide insights into strain performance that are transferable to in vivo. To this end, we perform tests on the interaction between microorganisms as well as those on the interaction between host and microorganism. In addition to this, using our molecular genetic tools we can elucidate the mechanism of action as a basis for process and quality control and prioritize the best strains for in vivo testing.

Product manufacturing

The manufacturing process involves much more than just the generation of (bio)mass. This is the stage that decides whether the probiotic retains its active potential until it is used and then develops its potential to maximum effect.

Based on our knowledge of the mechanism of action, we establish the production process on a laboratory scale and optimize the process parameters. This gives us significant influence on the yield of a stable and active product in the subsequent manufacturing process.

Control (tracking)

With probiotics, your products become "living products". This requires individually tailored quality control, which we develop according to the regulations of your field of application.
