Notes; Day 1; General Information, Classification

 

- Creates lactase

- Used to produce yogurt

- Discovered by Bulgarian scientist; hence "bulgaricus"

- also called lactobacillus delbrueckii bulgaricus because of discoverer(?)

- A rod-like bacteria

- Prevents vaginal yeast infections

- RECENT STUDIES have shown that it destroys bad-breath causing bacteria

- GRAM POSITIVE

- Low pH (4-5)

- Anaerobic

 

 

be sure to revisit in the future, however this is irrelevant to what the timeline dictates I am supposed to be researching.

Gram information:

- Gram positive

- cytoplasmic membrane

- peptydoglycan layer

- teichoic and lipoteichoic acids are present, used for adhesion

- polysaccharide capsules

- Gram positive forms Firmicutes, largest group

This is just first, general part of gram research. In gram page, I will describe the process of gram-staining, and what it determines.

 

Notes on habitat:

 

- acid tolerant

- lives in dairy products such as milk and yogurt

- used to live in plants

- lives on a restricted diet of carbohydrates

- also lives in human intestinal tract

 

Notes on History:

 

- Discovered in 1905 by Stamen grigorov

- genes once used to break down plant sugars are now breaking down and making room for new genes in the genome

 - l. bulgaricus jumped from plants to dairy and conjugated until its main habitat was dairy

- discontinued produced amino acids that it would need to survive off of plants

- began to break them down and absorb them in dairy

 

Notes on Reproduction:

 

- L. bulgaricus primarily uses conjugation to reproduce

- Considered the bacterial equivalent of "mating"

- both bacteria contains a chromosome, and a plasmid is transferred

- plasmid is transferred though the pilus*

 

Notes on Structure:

- rod shaped, forms chains

- can form into cocci and spirilla

- gram positve (distinguished by cell walls)

- internally composed of my cytoplasmic fluids and a nucleus

- low pH

- lactic acid bacteria, acidophilic

- does not have a flagella

- non spore forming

 

Notes on news and current events:

 

- cell size reduction recently

- this is because an increasingly large amount of RNA in the cell

- Rna = transmitter of genetic codes with genetic counterpart, DNA (deoxyribonucleic acid)

 

Notes on problems with removal from environment:

 

- speed and efficiency of the production of dairy would decrease

- human immune system would be vulnerable

- vitamin B defficiency??

- digestion problems?

 

Notes on FUN FACTS:

 

- Named after Bulgaria

- Helps people with lactose intolerance

- Is said to reduce BAD BREATH

- Prevents yeast infections

- Is a bacteria used in "bioglyph art", which are microscopic images used as art.

 

Notes on Nutritional Requirements:

 

- HETEROTROPHIC
