How Probiotic Biochemicals Work

What Are Probiotic Biochemicals?

Microbiology studies small, living things and looks at the way these microorganisms can be put to work in nearly every process on our planet. Every part of life also involves chemical reactions — chemistry examines how and why different substances combine, interact, react, and transform.

Proviera’s probiotic biochemicals combine microbiology with chemistry to produce products that perform chemical processes using microorganisms.

probiotic biochemicals bacteria
Like other organisms, microorganisms need food or fuel to function. As they break down the substances they “eat,” they create metabolites.

probiotic biochemicals molecules
Metabolites are small molecules (even smaller than other molecules) that because of their low weight, can easily enter other cells and interact with them.

probiotic biochemicals process
Proviera’s probiotic biochemicals are metabolites derived from the controlled fermentation of probiotic cultures and natural ingredients.

In leather tanning, these metabolites are small enough to penetrate inside the fibers of hides and skins. These metabolites are also hydrotropes.

How Do Proviera Probiotics Work?


Proviera’s probiotic biochemicals produce metabolites when in contact with leather hides.  These metabolites are hydrotropes that help both cleave off the collagen from the non-leather making substances, including fats, and disperse chemicals.

They also activate the ionic groups in the side of the protein chain, thus their affinity to the processing compounds.

Consequently, biochemicals can eliminate, reduce, or be combined with soaking and wetting agents, enzymes, degreasers, dispersing agents, and dye auxiliaries.

They can also improve leather quality by optimizing the up-taking of tanning and processing substances.

When to Use Probiotics in the Leather Tanning Process

Proviera’s probiotic biochemicals can be used throughout the leather tanning process.

Wash and Soak

Tanneries’ leather-making process begins when raw hides, either cured or fresh, are cleaned by removing dirt, dung, blood, hair, and salt. This step also opens up the collagen structure of the hides.

Proviera’s probiotic biochemicals can replace or reduce chemical soaking agents, mainly surfactants and enzymes.

Main Soak

During the main soak, hides and skins are rehydrated, bringing them to a flexible condition.

Probiotic biochemicals are an effective alternative to most chemical soaking agents, either surfactants or enzymes.

Unhairing and Liming

Hair is removed, and the action of alkalis (lime) swells the protein weave of hides and skins, creating limed pelts. Proviera’s probiotic biochemicals can be added as lime auxiliaries to help lime distribution, reducing wrinkles, relax, and flatter the pelts.

Probiotic biochemicals eliminate or reduce the use of amines, organic reductive agents, and polyphosphates


Degreasing strips off natural fats from adipose tissue to disperse and solubilize the leather’s natural fats.

Probiotic biochemicals replace — or at least drastically reduce — degreasing agents based from blends of surfactants and lipases. They can also remove the need for solvents, as they make it easier for natural fats to be stripped.
