What is the relationship between bacteria fungi and molds?

Fungi are prokaryotes, bacteria are eukaryotes, and molds are parasites and decomposers.

A general term for fungi in which molds form branched hyphae. Not a taxonomic noun, taxonomically belonging to the various subphyla of the phylum Fungida. The basic unit that makes up the mold is called hyphae, which are long tubular and 2 10 microns in width, which can continuously grow and branch from the front end.

No septum or septum, with 1 to more nuclei. When growing on a solid substrate, part of the hyphae penetrates deep into the substrate to absorb nutrients, which is called matrix hyphae or vegetative hyphae; The aerial hyphae that stretch into the air are called aerial hyphae, which can further develop into reproductive hyphae and produce spores. A large number of hyphae are interwoven into villous, flocculent, or reticulated, etc., which is called mycelium.

Mycelium is often white, brown, gray, or bright in color, and some can produce pigments to color the substrate. Mold multiplies rapidly, often causing a large number of mold and rot of food and utensils, but many beneficial species have been widely used, and it is the earliest type of microorganism used and recognized in human practice. Molds are a colloquial term for filamentous fungi, meaning "moldy fungi", that tend to form branched and luxuriant mycelium, but do not produce large fruiting bodies like mushrooms.

In moist and warm places, many objects grow some visible fluffy, flocculent or cobweb-like colonies, which are molds. The hyphae of mold. The basic unit that makes up the vegetative body of a mold is the hyphae.

Hyphae are a kind of tubular filaments, which are viewed under a microscope and resemble a transparent hose, and its diameter is generally 3-10 microns, which is about several to dozens of times thicker than the cells of bacteria and actinomycetes. The hyphae can elongate and produce branches, and the mycelium of many branches are intertwined with each other, which is called mycelium.

Colonies, also known as colonies. It refers to a group of daughter cells that are grown and multiplied to a certain extent by a single or a small number of microbial (bacterial or fungal) cells on the surface or inside of a suitable solid medium to form a group of daughter cells with the mother cell as the center that is visible to the naked eye and has certain morphological and structural characteristics.

Different microorganisms form colonies with different characteristics, which are important markers for the identification of strains.

The colony characteristics formed by various microorganisms under certain conditions, such as size, shape, edge, surface, texture, color, etc., have a certain stability, which is an important basis for measuring the purity of the strain, identifying and identifying the strain. The characteristics of colonies are closely related to the morphological and structural characteristics of microorganisms.

1. The colonies that grow on the surface of the medium are called surface colonies;

2. Colonies that grow under the surface are called buried or deep colonies.

Cell morphology is the basis of colony morphology, and colony morphology is the reflection of cell morphology when a colony gathers. The characteristics of the colony are determined by the cell structure and growth behavior of the colony, such as the capsule of the micro-bacteria, and its presence or absence is directly related to the morphology of the colony.

The characteristic description of the micro-bacterial colony should include: size, morphology, color, gloss, transparency, texture, bulge state, edge characteristics, etc. Commonly used descriptive terms are as follows:

1. Size: the range covered by the colony, generally describing the diameter of the colony.

2. Morphology: refers to the appearance and shape of the colony, and common words include round, oval, triangular, irregular shape, etc.

3. Color: including the front and back colors, that is, the color of aerial hyphae and intrabasal hyphae, common words include: white, milky white, red, pink, black, colorless, etc.

4. Glossiness: refers to whether the surface is glossy, which can be directly described as the surface of the colony is shiny, matte, smooth and rough, etc. Generally, colonies with capsules have a shiny surface, and colonies without capsules have a dull surface.

5. Transparency: Describe the nature of light transmission of colonies, and common words include: transparent, translucent, and opaque.

6. Texture: refers to the viscosity and brittleness of the colony, and common words include: waxy, dry, easy to provoke, viscous, etc.

7. Bulge state: refers to the morphology of the colony section, and common words include: bulge, bulge, flattening.

8. Edge characteristics: refers to the shape of the periphery of the colony, and common words include: wavy, complete, powdery, rodent, etc.

Streptomyces belongs to the kingdom Bacteria, Streptomyces spp., and is a class of gram-positive bacteria. Although Streptomyces is morphologically divided into hyphae and spores, it is similar to fungi in culture characteristics and reproduces mainly through spores.

However, Streptomyces does not have a real nucleus and a strong cell wall, and the size is basically the same as the diameter of bacteria, and the pH range for the most suitable growth is basically the same as that of bacteria, and it is generally slightly alkaline. In addition, Streptomyces is susceptible to antibiotics and not to antifungal drugs. The mode of reproduction is asexual reproduction, and the genetic characteristics are similar to those of bacteria.

Streptomyces are bacteria.

A family of actinomycetes. The intrabasal hyphae do not break, and the aerial hyphae are usually well developed, forming long (and sometimes short) spore filaments. The spores are immotile and often have warts, spines, or hairs on the outer sheath.

Color varies from species to species and is one of the main identifying traits for classification. More than 1,000 species have been reported, mainly in the soil.

The bacterium Streptomyces is a family of actinomycetes.

The high biological range distinguishes between bacteria and fungi in such a way: bacteria have words in their names that indicate their shape, such as "rod" for "E. coli", "spiral" for "Helicobacter pylori", "ball" for "staphylococci". "Lactobacillus" is a bacterium because it is of the genus "Lactobacillus".

This is not the case with fungi such as yeasts.

Bacteria are generally single-celled, with a simple cell structure and a lack of nucleus and cytoskeleton.

and membranous organelles. The shapes are quite diverse, mainly spherical, rod-shaped, and spiral-shaped. Mold is a type of fungus that is characterized by a well-developed mycelium and no larger fruiting body. There is a cell wall.

Survive in a parasitic or saprophytic manner.

Bacteria and molds are microorganisms, which have the characteristics of small size, large area, vigorous growth, fast reproduction, wide distribution and many species. But they differ in their type, structure, size, way of proliferating, and name.

Difference Between Bacteria and Mold

Bacteria belong to the bacterial domain and are the most abundant of all organisms, with an estimated total of about 5 10 30 individuals. The shapes of bacteria are quite varied, mainly globular, rod-shaped, and spiral-shaped. Bacteria are very small, and the smallest known bacteria are only micrometers long, so most of them can only be seen under a microscope.

Bacteria are generally unicellular cells with a simple cell structure that lacks a nucleus, cytoskeleton, and membranous organelles, such as mitochondria.

and chloroplasts. Mold is a type of fungus that is characterized by a well-developed mycelium and no larger fruiting body. Like other fungi, they also have cell walls, parasitism or saprophytic modes of survival.

Mold can turn food into toxic substances, and some may produce toxins in food, known as mycotoxins.
