Aliphatic, Cyclic, and Aromatic Organic Acids, Vitamins, and Carbohydrates in Soil: A Review

Abstract

Organic acids, vitamins, and carbohydrates represent important organic compounds in soil. Aliphatic, cyclic, and aromatic organic acids play important roles in rhizosphere ecology, pedogenesis, food-web interactions, and decontamination of sites polluted by heavy metals and organic pollutants. Carbohydrates in soils can be used to estimate changes of soil organic matter due to management practices, whereas vitamins may play an important role in soil biological and biochemical processes. The aim of this work is to review current knowledge on aliphatic, cyclic, and aromatic organic acids, vitamins, and carbohydrates in soil and to identify directions for future research. Assessments of organic acids (aliphatic, cyclic, and aromatic) and carbohydrates, including their behaviour, have been reported in many works. However, knowledge on the occurrence and behaviour of D-enantiomers of organic acids, which may be abundant in soil, is currently lacking. Also, identification of the impact and mechanisms of environmental factors, such as soil water content, on carbohydrate status within soil organic matter remains to be determined. Finally, the occurrence of vitamins in soil and their role in biological and biochemical soil processes represent an important direction for future research.

Effect of soil sieving on respiration induced by low-molecular-weight substrates

“…Phenolics and salicylate are quickly metabolized, and salicylate supports metabolism of fungi, whereas phenolics supports bacterial metabolism. Decreased of effects of phenolics on soil properties from A to B horizons was reported by Vranova et al (2013). CONCLUSIONS 1.…”

“…Free amino acids in soil occur in concentrations of a mM to mM range, carbohydrates in soil solution and NaOH extracts in concentrations up to 358 mg kg -1 , and individual water-soluble phenolics in concentrations up to 600 mg kg -1 (Rejsek et al, 2010;Vranova et al, 2013).…”

Soil Scientific Research Methods Used in Archaeology - Promising Soil Biochemistry: a Mini-review

“…Soil biochemistry as a whole seems to be an important tool as well Collins, 2000, 2002;D'Anjou et al, 2012;Vranová et al, 2012;Vranová et al, 2013a). This is because it adequately takes into account the following; mineralisation processes, decomposition processes, enzymatic processes and soil organic compounds composition, soil polysaccharides and lipids in particular.…”

Glycoside Hydrolases across Environmental Microbial Communities

“…In soil [21], sludge and wastewater (referred to as sludge below) [22], and in the phyllosphere [23], microbes are exposed to an abundant—and varying—complex mixture of carbohydrates (e.g., cellulose, xylan, and fructan from plant material and chitin from fungi and arthropods). In aquatic systems (i.e., marine, mats, and larger fresh water environments), the carbohydrate supply is reduced, and chitin is the most common polymer [24–26].…”
