What is LACTOBACILLUS BULGARICUS ？

Lactobacillus bulgaricus is a gram-positive, rod-shaped bacteria that is commonly found in fermented milk products such as yogurt. It is a lactic acid bacteria that is used as a starter culture in the production of yogurt and other fermented milk products.

Some of the main features of Lactobacillus bulgaricus include:

Rod-shaped: Under microscope, Lactobacillus bulgaricus appears as rod-shaped bacteria.

Non-motile: Lactobacillus bulgaricus does not have flagella and is not motile.

Facultative anaerobic: Lactobacillus bulgaricus is a facultative anaerobic bacteria, which means it can grow both in the presence and absence of oxygen.

Ferments carbohydrates: Lactobacillus bulgaricus ferments carbohydrates and produces lactic acid as a main by-product.

Probiotic: It is a probiotic bacteria, meaning it can promote health and balance the gut microbiome.

Thermophilic: Lactobacillus bulgaricus is a thermophilic bacteria, which means it can grow at high temperatures.

Often found in yogurt: Lactobacillus bulgaricus is one of the most common bacteria found in yogurt, along with Streptococcus thermophilus.

It is a good source of Vitamin B12.

It’s worth noting that the specific features of Lactobacillus bulgaricus may vary depending on the strain and the growth conditions used. Additionally, the features of the bacteria can also be influenced by the method used to prepare and view the sample (e.g. gram staining, culture, etc).

Appearance of LACTOBACILLUS BULGARICUS？

Lactobacillus bulgaricus is a gram-positive, rod-shaped bacteria. It is non-motile and does not form spores. Under a microscope, Lactobacillus bulgaricus appears as long, slender rods that are usually arranged in chains or clusters. The cells are typically between 0.5 and 1.0 micrometers in width and 1.5 to 10 micrometers in length. Lactobacillus bulgaricus is a facultative anaerobe, which means that it can grow in the presence or absence of oxygen.

In culture, Lactobacillus bulgaricus forms smooth, glossy, white or cream-colored colonies that are circular and slightly convex. The colonies are usually 1-3mm in diameter and may have a slightly raised center. They are opaque and may have a slight metallic sheen. They are non-hemolytic and have a homogeneous texture.

It’s worth noting that the appearance of Lactobacillus bulgaricus can vary depending on the specific strain and the conditions under which it is grown. Additionally, the appearance of the bacteria in culture may not necessarily reflect its appearance in its natural environment.

 

Active ingredient of LACTOBACILLUS BULGARICUS？

Lactobacillus bulgaricus is a probiotic bacteria that is commonly used in food fermentation, particularly in the production of yogurt. As a probiotic, it is considered safe for human consumption and has been shown to have several health benefits.

Lactobacillus bulgaricus produces lactic acid as a primary metabolic end-product. This acidity helps to preserve the fermented food and also provides a favorable environment for the growth of other lactic acid bacteria. Additionally, Lactobacillus bulgaricus has been shown to produce other compounds such as hydrogen peroxide, acetic acid, and bacteriocins, which have antimicrobial properties.

Lactobacillus bulgaricus also has been shown to produce exopolysaccharides (EPSs) that can help to improve the texture and consistency of fermented foods. EPSs can also help to protect the bacteria from harsh environmental conditions, such as changes in pH or the presence of antibiotics.

It’s worth noting that the specific active ingredients produced by Lactobacillus bulgaricus can vary depending on the strain and the conditions under which it is grown. Additionally, some studies have suggested that different strains of Lactobacillus bulgaricus may have different health benefits.
