Soil microbiology. Soil microbiology is the study of microorganisms in soil, their functions, and how they affect soil properties. [1] It is believed that between two and four billion years ago, the first ancient bacteria and microorganisms came about on Earth's oceans.
The average population of Ohio's counties was 133,931; Franklin County was the most populous (1,326,063) and Vinton County was the least (12,474). The average land area is 464 sq mi (1,200 km 2). The largest county by area is Ashtabula County at 702.44 sq mi (1,819.3 km 2), and its neighbor, Lake County, is the smallest at 228.21 sq mi (591.1 ...
Streptococcus is a genus of gram-positive (pl.: cocci) or spherical bacteria that belongs to the family Streptococcaceae, within the order Lactobacillales (lactic acid bacteria), in the phylum Bacillota. [2] Cell division in streptococci occurs along a single axis, thus when growing they tend to form pairs or chains, which may appear bent or ...
Soil biology is the study of microbial and faunal activity and ecology in soil. Soil life, soil biota, soil fauna, or edaphon is a collective term that encompasses all organisms that spend a significant portion of their life cycle within a soil profile, or at the soil- litter interface. These organisms include earthworms, nematodes, protozoa ...
Soil formation. Soil formation, also known as pedogenesis, is the process of soil genesis as regulated by the effects of place, environment, and history. Biogeochemical processes act to both create and destroy order (anisotropy) within soils.
Members of this phylum are physiologically diverse, and can be found in a variety of environments including soil, decomposing wood, [7] hot springs, oceans, caves, and metal-contaminated soils. [8] The members of this phylum are particularly abundant in soil habitats representing up to 52% of the total bacterial community. [9]
The Actinomycetota (or Actinobacteria) are a diverse phylum of Gram-positive bacteria with high GC content. [ 4 ] They can be terrestrial or aquatic. [ 5 ] They are of great importance to land flora because of their contributions to soil systems. In soil they help to decompose the organic matter of dead organisms so the molecules can be taken ...
Denitrifying bacteria have been identified in over 50 genera with over 125 different species and are estimated to represent 10-15% of bacteria population in water, soil and sediment. [3] Denitrifying include for example several species of Pseudomonas, Alcaligenes, Bacillus and others. Pseudomonas stutzeri, a species of denitrifying bacteria
