Characteristics Of Bacteria Bacteria mainly comprises a simple cellular structure, including: Capsule Cell wall Flagellum Pili Cytoplasm Ribosomes Chromosomes. Some bacteria are found as individual cells.Others grow in groups or in long chains of cells. 2. Introduction. Bacteria grow on nutrient mediums as colonies. Only a small percentage, less than 10%, of all known bacteria are pathogenic, or able to cause disease in a susceptible host. Three bacterial strains and a yeast previously isolated from different environments were investigated. Much is being written about the human microbiome, the trillions of invisible microbes that live in and on our bodies. Click here to view We have moved all content for this concept to for better organization. 1. In the studied rocks, we also noted a rather high number of silicate bacteria (1.0 × 10 4 -2.2 × 10 4 cells/g) and microorganisms of the nitrogen cycle, especially heterotrophic nitrate bacteria (1.2 × 10 3 -8.4 × 10 4 cells/g), which indicates the ongoing decomposition of nitrogen-containing organic substances to ammonia and oxidation of nitrogen compounds, as well as the destruction . Microorganisms are very widely distributed, and are . Size Range Bacteria range in size from 0.5 to 2 microns in diameter and about 1 to 10 microns in length. In this section, we will describe four classes of gram-negative nonproteobacteria: Chlamydia, the spirochetes, the CFB group, and the Planctomycetes. Therefore, understanding the distribution and population structure characteristics of microorganisms in drainage pipes network is important for the safe operation and management of the sewage system.
