In some tanning processes, yes. But not in others.
One very old process for tanning leather used layers of leather and animal dung, it was allowed to ferment for months. That used bacteria and fungi, but nobody knew it when the process was developed.
Bacteria is used in the pre-tanning processes ,i.e, soaking, dehairing, bating and degreasing. And most important it produces proteolytic enzymes known as proteases which are extracted and used in dehairing, soaking and bating processes which is required to produce leather.
Leather tanning is a chemical change, as it involves the chemical reaction of tanning agents with proteins in the hide to create a more stable material. This process transforms the hide into leather by altering its chemical structure.
Prefered methods of the native peoples in the northern parts of the world; The Saami in northern Europe, the Chukchee in NE Russia, the Eskimo and Inuit along the northern tier of North America, who all make relatively soft 'bark tanned' leathers. Apears to be Alder bark. Though i have heard of the Saami using Birch bark as well.
Natural resources used to make a pair of shoes include leather from animals, rubber from rubber trees, cotton for some components, and various metals and minerals for elements like eyelets and buckles. These resources go through processes such as tanning, rubber harvesting, and mining to be transformed into shoe components.
Leather can be either natural or synthetic. Natural leather is made from the hides of animals, typically cattle, and undergoes a tanning process to preserve and enhance its durability and appearance. Synthetic leather, on the other hand, is made from artificial materials like polyurethane or PVC, designed to mimic the look and feel of real leather without using animal products. Both types have their own advantages and applications, depending on consumer preferences and ethical considerations.
It is used for the tanning of leather
Kid leather is a soft leather made from tanning sheep and goat hides. Kid leather is used for gloves and coats.
Bacteria play a crucial role in the leather industry through the process of bating. During this stage, proteolytic bacteria break down proteins in animal hides, softening the leather and improving its texture. These microorganisms also help remove unwanted hair and flesh, enhancing the quality of the final product. Additionally, certain bacteria are used in the tanning process to produce enzymes that accelerate leather production and increase its durability. By harnessing the power of these microscopic organisms, the leather industry achieves superior results in terms of texture, flexibility, and overall quality.
A barkometer is a hydrometer calibrated to test the strength of tanning liquors used in tanning leather.
A medieval tannery was used for tanning leather.

It's used to preserve the hides when its first flashed prior to tanning.
economic importance of bacteria : useful role in medicine : antibiotics , serums,vaccines role in agriculture : nitrogen fixing bacteria,nitrifying bacteria, denitrifying bacteria role in industry:flavours of tea, leather tanning
The leather tanning and finishing industry must meet Environmental Protection Agency
Sheepskin leather is the skin of a sheep that has been tanned. Tanning preserves the leather. Tanning sheepskin is the same process as tanning cow hides, a more common type of leather. Sheepskin is finer grained than cow.

Yes, leather is opaque. It is a thick material that does not allow light to pass through it. This is due to the dense fibers and tanning process used to create leather.
