Plant expression of thermostable endoglucanase (E1) [pdb:1ECE] has been proposed for improved conversion of lignocellulose to ethanol for fuel production. Since E1 was isolated from hot springs and has thermostable properties, it may have increased stability when released to agricultural soils during post-harvest residue decomposition. Endoglucanases are a subclass of cellulases and act by clea...
A series of combined measurements was made at the Naval Air Station North Island (NASNI) Installation Restoration Site 5, Unit 2 during July and August 2013. Combined measurements included CO2 respiration rate, CO2 radiocarbon content to estimate chlorinated hydrocarbon (CH) mineralization and a zone of influence (ZOI) model. CO2 was collected continuously over 2 two-week periods by recirculati...
Carbon capture and storage (CCS) provides a solution toward decarbonization of the global economy. The success of this solution depends on the ability to safely and permanently store CO2 This study demonstrates for the first time the permanent disposal of CO2 as environmentally benign carbonate minerals in basaltic rocks. We find that over 95% of the CO2 injected into the CarbFix site in Icelan...

Soil net nitrogen (N) mineralization (Nmin ) is a pivotal process in the global N cycle regulating the N availability of plant growth. Understanding the spatial patterns of Nmin, its temperature sensitivity (Q10 ) and regulatory mechanisms is critical for improving the management of soil nutrients. In this study, we evaluated 379 peer-reviewed scientific papers to explore how Nmin and the Q10 o...
Inputs of dissolved organic carbon (DOC) to lakes derived from the surrounding landscape can be stored, mineralized or passed to downstream ecosystems. The balance among these OC fates depends on a suite of physical, chemical, and biological processes within the lake, as well as the degree of recalcintrance of the allochthonous DOC load. The relative importance of these processes has not been w...
Marine dissolved organic matter (DOM) is one of the largest reservoirs of reduced carbon on Earth. In the dark ocean (4200m), most of this carbon is refractory DOM. This refractory DOM, largely produced during microbial mineralization of organic matter, includes humic-like substances generated in situ and detectable by fluorescence spectroscopy. Here we show two ubiquitous humic-like fluorophor...
In natural and laboratory-based environments experiencing sustained counter fluxes of sulfide and oxidants, elemental sulfur (S(0))-a key intermediate in the sulfur cycle-can commonly accumulate. S(0) is frequently invoked as a biomineralization product generated by enzymatic oxidation of hydrogen sulfide and polysulfides. Here we show the formation of S(0) encapsulated in nanometre to micromet...
Important due to both its role in fire-affected ecosystems, and also its proposed intentional production and application for carbon (C) management, pyrogenic organic matter (PyOM) is thought to contain very stable forms of C. However, the mechanisms behind its interactions with non-PyOM soil organic C (SOC) remain speculative, with studies often showing short-term positive and then long-term ne...
Aiming to sequestrate the excessive carbon dioxide and convert acidified seawater, an improved method of mineralization is developed based on electrode separation mechanism extra oxygen-supplying technique. By neutralizations anodic acidity cathodic alkalinity, as well precipitation dissolution calcium carbonate (CaCO3), are prevented. In addition, extra-supplied oxygen prevents evolution hydro...
