Exercise 6: Isolation and Characterization of Bread Molds and Fruit Molds

molds

among the largest organisms studied in microbiology; filamentous fungi; typically large, fluffy, and light in texture resulting from the presence of aerial hyphae and spore-producing structures

fruiting heads

spore-producing structure

methylene blue

used as an optional alternative when LPCB 

hyphae

each of the branching filaments that make up the mycelium of a fungus

septate

having or partitioned by a septum or septa

septum

a cross-wall that divides a fungal hypha into separate cells

Rhizopus sp.

common bread mold

sporangiophore; sporangium; sporangiospores

3 parts of the common bread mold

sporangiophore

a specialized hypha bearing sporangia

sporangium

of common bread molds; a receptacle in which asexual spores are formed

sporangiospores

asexual spores formed inside a walled sporangium

Penicillium sp.

common citrus fruit mold

conidiophore; vegetative hyphae; conidium

3 parts of the common citrus fruit mold

conidiophore

a conidium-bearing hypha or filament.

conidium

a spore produced asexually by various fungi at the tip of a specialized hypha

vegetative hyphae

branching, thread-like filaments that make up the feeding and growth structure of a fungus, forming a mass called the mycelium

Basidiomycota; Ascomycota; Zygomycota; Chytridiomycota

four divisions of fungi

Basidiomycota

genus Agaricus

Ascomycota

genus Saccharomyces

Zygomycota

genus Rhizopus

Chytridiomycota

genus Nowakowskiella

mycelium

a tangled mass of branching hyphae that forms the visible body or thallus of the mold

1928

the year the first antibiotic was developed

Penicillium notatum

the specific species of Penicillium discovered by Alexander Fleming to produce the first antibiotics

mycoses

diseases caused by a fungus (yeast/mold); also called fungal infections

tinea pedis

athlete’s foot

tinea capitis

scalp ringworm

tinea cruris

groin ringworm

onychomycosis/tinea unguium

nail ringworm

tinea barbae

beard ringworm

tinea versicolor

skin discoloration

oral candidiasis

oral thrush

vaginal candidiasis/vulvovaginal candidiasis (VVC)

vaginal yeast infection

candida onychomycosis

nail candidiasis

Trichophyton; Epidermophyton; Microsporum

3 genus of dermatophyte fungi

Candida albicans

causative agent of candidiasis
