Date Mar. 18, 1993A cyclical process for degrading waste organic matter to gaseous products and substantially zero volume of solid matter by subjecting the waste alternately and cyclically to stages of mesophilic and thermophilic digestion in which the organisms from one stage are inactivated and ...
Thus, it is possible that nitrification is one of the dominant processes within the lake, sustained by the decomposition of nitrogenous organic matter in the sediments3. The lake was aerobic at the time of sampling, but the sediments were inferred to become anoxic at a depth of ~ 15 cm ...
■ Sampling on the continental shelves and along the base of the continental slopes has shown that fine muds beneath the seafloor contain up to 8 percent organic matter. ■ Two additional kinds of evidence support the hypothesis that petroleum is a product of the decomposition of organic matter:...

Dissolved organic matter (DOM) is a heterogeneous mixture of organic compounds that is produced through both microbial degradation and abiotic leaching of
do not cause the decomposition of individual pollutants contained in the sewage, but only their transfer from one phase to another, for example, from sewage to sewage sludge, which in the case of harmful substances does not solve the problem holistically (Sun et al., 2020; Ateş and Argun...
(either terrestrial or aquatic). In such cases, it is referred to as sedimentary ancient DNA orsedaDNA. SedaDNA samples hold genetic information of all living organisms that have interacted with a given layer or context. Therefore, sedaDNA has been embraced in paleoecology as one of the main...
Minerals are widely assumed to protect organic matter (OM) from degradation in the environment, promoting the persistence of carbon in soil and sediments. In this Review, we describe the mechanisms and processes operating at the mineral–organic interface as they relate to OM transformation dynamics...
The majority of life on Earth is dependent upon six critical elements: hydrogen (H), carbon (C), nitrogen (N), phosphorus (P), oxygen (O), and sulfur (S) that pass through, and are transformed by,soil organisms (the soil biota). The process ofbiogeochemical cyclingis defined as the ...
