Deep influence of soil microbes.
A single gram of soil is said to contain more than 8 billion bacterial cells, representing up to 50,000 different species1. These microorganisms play important roles, from tweaking how plants interact with their surroundings to influencing the chemical composition of the environment2. Now, the increased affordability of DNA sequencing technologies has enabled scientists to gain a deeper underst...
متن کاملThe role of soil microbes in plant sulphur nutrition.
Chemical and spectroscopic studies have shown that in agricultural soils most of the soil sulphur (>95%) is present as sulphate esters or as carbon-bonded sulphur (sulphonates or amino acid sulphur), rather than inorganic sulphate. Plant sulphur nutrition depends primarily on the uptake of inorganic sulphate. However, recent research has demonstrated that the sulphate ester and sulphonate-pools...
متن کاملPolythene and Plastics-degrading microbes from the mangrove soil
Biodegradation of polythene bags and plastic cups was analyzed after 2, 4, 6, and 9 months of incubation in the mangrove soil. The biodegradation of polythene bags was significantly higher (up to 4.21% in 9 months) than that of plastic cups (up to 0.25% in 9 months). Microbial counts in the degrading materials were recorded up to 79.67 x 104 per gram for total heterotrophic bacteria, and up to ...
متن کاملSoil microbes drive the classic plant diversity-productivity pattern.
Ecosystem productivity commonly increases asymptotically with plant species diversity, and determining the mechanisms responsible for this well-known pattern is essential to predict potential changes in ecosystem productivity with ongoing species loss. Previous studies attributed the asymptotic diversity-productivity pattern to plant competition and differential resource use (e.g., niche comple...
متن کاملIdentification of Soil Microbes Capable of Utilizing Cellobiosan
Approximately 100 million tons of anhydrosugars, such as levoglucosan and cellobiosan, are produced through biomass burning every year. These sugars are also produced through fast pyrolysis, the controlled thermal depolymerization of biomass. While the microbial pathways associated with levoglucosan utilization have been characterized, there is little known about cellobiosan utilization. Here w...
