Concept: Bacterial cellulose is a form of cellulose resulting from biosynthesis performed by bacteria from the genera Glucanacetobacter, Agrobacterium, Rhizobium, Sarcina, Alcaligenes, etc., from which the most efficient and, consequently, more thoroughly studied is Glucanacetobacter xylinus. It was in the culture medium of these gram-negative, anaerobic bacteria, often found in fruits, vegetables, vinegar and fermented […]

Cell Biology’s definition (Cytology) Cell Biology is the Biology’s branch which study the cell, focusing on its function, structure, physiological features, constituents, life cycle, division, death and interactions with other cells and surrounding environment. This branch of Biology covers both the study of single-cell organisms (bacteria and protozoa) as the study of more complex organisms, […]

Molecular Biology is a branch of Biology that studies the cell at a molecular level. It has the main objective of studying the biochemical interactions between the different systems of the cell. It also studies in which way these interactions are regulated, focusing on the relationship between structure and function of genetic material (DNA and […]
