There isn't a single "name" for decomposing bacteria. Instead, there are many different types of bacteria that contribute to decomposition, each with its own scientific name. Here's a breakdown:

General Categories:

* Aerobic Bacteria: These bacteria require oxygen to survive and thrive. They break down organic matter in the presence of oxygen, releasing carbon dioxide, water, and nutrients as byproducts.

* Anaerobic Bacteria: These bacteria can survive and thrive in environments without oxygen. They break down organic matter using other electron acceptors, such as nitrates or sulfates, and release methane, hydrogen sulfide, and other byproducts.

Specific Examples:

* Bacillus: A genus of bacteria known for their ability to decompose cellulose (a major component of plant cell walls) and other organic materials.

* Pseudomonas: Another genus of bacteria that plays a vital role in decomposition, especially in the breakdown of proteins and lipids.

* Clostridium: A genus of anaerobic bacteria, some of which produce potent toxins. They are important in the decomposition of proteins and carbohydrates.

* Streptomyces: A genus of bacteria that produce antibiotics and are crucial in the breakdown of complex organic materials.

Important Note: Decomposers are not limited to bacteria. Fungi also play a vital role in breaking down dead organic matter.

If you're looking for more specific names, you could consider researching bacteria that are associated with specific types of decomposition, such as:

* Composting: *Bacillus subtilis*, *Lactobacillus*, *Streptomyces*

* Wastewater treatment: *Nitrosomonas*, *Nitrobacter*

* Soil decomposition: *Bacillus*, *Pseudomonas*, *Rhizobium*
