AZOSPIRILLUM BRASILENSE Meaning and
Definition
-
Azospirillum brasilense is a species of gram-negative, nitrogen-fixing bacteria that belongs to the genus Azospirillum. It is commonly found in the soil, particularly around plant roots, where it establishes a beneficial symbiotic relationship with various agricultural crops. This bacterium has a characteristic spiral shape and is highly motile due to the presence of flagella, enabling it to move efficiently in the soil matrix.
Azospirillum brasilense is renowned for its ability to fix atmospheric nitrogen and convert it into a form that can be readily utilized by plants. It achieves this through the process of biological nitrogen fixation, which reduces dependency on chemical fertilizers and contributes to sustainable agriculture. By facilitating nitrogen assimilation, this bacterium promotes plant growth, improves nutrient uptake, and enhances crop yields.
Furthermore, Azospirillum brasilense is known to produce an array of growth-promoting substances, including phytohormones such as auxins, gibberellins, and cytokinins. These compounds help regulate various physiological processes in plants, such as cell division, elongation, and differentiation, resulting in enhanced root and shoot development. Additionally, this bacterium can solubilize phosphate and produce siderophores, which aid in nutrient acquisition by plants.
Due to its numerous beneficial effects on plant growth and nutrition, Azospirillum brasilense has gained considerable attention in the field of agricultural biotechnology. It is often used in biofertilizers and bioinoculants to improve crop productivity, particularly in maize, wheat, rice, and various other economically important crops.

Etymology of AZOSPIRILLUM BRASILENSE
The word "Azospirillum" originates from the combination of two parts: "azo" and "spirillum".
1. "Azo" comes from the Greek term "azos", meaning "nitrogen". This term signifies the nitrogen-fixing ability of the bacteria Azospirillum, as it plays a crucial role in fixing atmospheric nitrogen into a form usable by plants.
2. "Spirillum" originates from the Latin word "spirilla", which refers to a type of bacteria characterized by their spiral or helical shape. This term describes the morphology of Azospirillum and its close relation to bacteria that exhibit a spiral shape.
The subspecies name "brasilense" identifies the geographic origin of the bacterium Azospirillum brasilense. It refers to Brazil, the country where this particular strain of bacteria was first discovered and isolated.
