Habitat Typically found in damp, dark or steam-filled areas. Very common. Can be found on fruit and berries, in the stomach of mammals and on skin, among other places.


Cell Multicellular (multiple celled) Unicellular (one cell)


Shape Filamentous fungi, Threadlike Round or oval in shape


Appearance Fuzzy appearance and can be an orange, green, black, brown, pink or purple in color. White and thready.


Hyphae Molds have microscopic filaments called hyphae. Yeasts do not have true hyphae. Instead they form

multicellular structures

called pseudo-hyphae.


Types There are 400,000 types of molds. There are 1500 types of yeasts.


Sporing Mold is a sporing fungi Yeast is a not a sporing species of fungi.


Reproduction Sexually and asexually reproduce into multi-cellular form. They reproduce mostly asexually (budding).


Asexual Spores Sporangiospores and Conidia Blastospore


Sexual Spores Zygospores, Ascospores, and Basidiospores No Sexual Spores.


Colorful Molds are very colorful compared to yeast. Yeast are less colorful compared to molds (colorless).


Examples Alternaria, Aspergillus, Fusarium, Mucor, Penicillium, Rhizopus, Trichophyton, etc. Saccharomyces cerevisiae, Cryptococcus neoformans, etc.


Energy Production Secrete hydrolytic enzymes that degrade biopolymers such as starch, cellulose and lignin into simpler substances that can be absorbed. Convert carbohydrates to alcohol and carbon dioxide in anaerobic through fermentation. Also obtain carbon from hexose sugars.


Uses Useful in biodegradation, food production (cheese) Making of alcoholic beverages which contain ethanol, used in baking, bioremediation, industrial ethanol production, probiotics, and food addictive or flavors.


Health Hazards Can cause allergic reactions and respiratory problems. Can cause infection in individuals with compromised immune systems.

  1. Nice lecture, pls can I join u to discover more moulds nd how to use them. They re important nd useful. I am frm nigeria

  2. That is a very wonderful job sir keep it up.

  3. Thanks for your clear answer. Can I ask you another question? Can Electro Magnetic Fields cause Candidiasis (yeast overgrowth). Our bedroom was 30 meters from a cell tower for approximately six years. It caused a number of symptoms which we were able to positively identify with wireless radiation. Later, after following an anti-candida diet for a few weeks, we had the same symptoms that we had from the EMF. Have you ever heard that wireless radiation can cause candida to overgrow? Thanks for your time.

  4. Thank you very much sir.

  5. Thanks for giving us more knowledge

  6. thanks for giving us more knowledge

  7. Nice to know about your work
