Yeasts are eukaryotic micro-organisms classified in the kingdom fungi, with 1,500 species currently described estimated to be only 1% of all fungal species. Most reproduce asexually by mitosis, and many do so by an asymmetric division process called budding. Yeasts are unicellular, although some species with yeast forms may become multicellular through the formation of a string of connected budding cells known as pseudohyphae, or false hyphae, as seen in most molds. Yeast size can vary greatly depending on the species, typically measuring 3–4 µm in diameter, although some yeasts can reach over 40 µm.
By fermentation, the yeast species Saccharomyces cerevisiae converts carbohydrates to carbon dioxide and alcohols – for thousands of years the carbon dioxide has been used in baking and the alcohol in alcoholic beverages. It is also extremely important as a model organism in modern cell biology research, and is one of the most thoroughly researched eukaryotic microorganisms. Researchers have used it to gather information about the biology of the eukaryotic cell and ultimately human biology. Other species of yeast, such as Candida albicans, are opportunistic pathogens and can cause infections in humans. Yeasts have recently been used to generate electricity in microbial fuel cells, and produce ethanol for the biofuel industry.
Your love shows many colours
Roses will show their thorns
You showed me signs of silence
Showed me my way back home
I break my back, bent over
I dance on broken glass
I hold my breath half to death
You can't forget the past
Unless you think it's not over
Let's kiss it goodbye
Is it really worth it?
Is it all just a lie?
Not like I'm giving up now, I am willing to try
Unless you think it's not over
Let's kiss it goodbye
My love shows it's horns
Could you lead us home?
Break your,
Break your back on broken glass
You can't forget the past
Unless you think it's not over
Let's kiss it goodbye
Is it really worth it?
Is it all just a lie?
Not like I'm giving up now, I am willing to try
Unless you think it's not over
Let's kiss it goodbye
My love shows many colours
Devils will show their horns
I lead you into darkness
Hoped it would lead us home
You break your back, bent over
You dance on broken glass
I know you'll always love me
You can't forget the past
Unless you think it's not over
Let's kiss it goodbye
Is it really worth it?
Is it all just a lie?
Not like I'm giving up now, I am willing to try
Unless you think it's not over
Let's kiss it good
