Journal ArticleDOI
Effect of Biochar on Microbial Growth: A Metabolomics and Bacteriological Investigation in E. coli.
Rebecca A Hill,John Hunt,Emily Sanders,Melanie Tran,Griffin A. Burk,Todd E. Mlsna,Nicholas C. Fitzkee +6 more
TL;DR: It is suggested that biochar can serve as a beneficial soil amendment while minimizing the impact on bacterial viability, and a mechanism for biochar's effectiveness in soil conditioning is identified and how bio char can alter specific bacterial metabolic pathways is revealed.
Journal ArticleDOI
Adsorption performance of standard biochar materials against volatile organic compounds in air: A case study using benzene and methyl ethyl ketone
TL;DR: In this paper, the performance of 12 standard biochars made of six different raw materials (i.e., Miscanthus straw pellets, oil seed rape straw, rice husk, sewage sludge, soft wood pellets, and wheat straw pellets) against two model gaseous VOCs at pyrolysis temperature conditions was investigated.
Journal ArticleDOI
Biochar based remediation of water and soil contaminated by phenanthrene and pentachlorophenol.
TL;DR: In soil remediation experiments, addition of two biochar rates, i.e. 2.5 and 5 mg g-1, strongly reduced Phe extractability, while larger amount of biochar allowed reduction of the extractable PCP and nullified phytotoxicity of the contaminant.
Journal ArticleDOI
Gas permeability of biochar-amended clay: potential alternative landfill final cover material
TL;DR: The results from the present study imply that compacted BAC can be used as an alternative final cover material with decreased gas permeability when compared with clay.
Journal ArticleDOI
Increased biomass and quality and reduced heavy metal accumulation of edible tissues of vegetables in the presence of Cd-tolerant and immobilizing Bacillus megaterium H3.
TL;DR: The results demonstrated the increased edible tissue biomass and quality, decreased Cd and Pb uptake of the edible tissues, and improved soil quality in the presence of strain H3 and suggested an effective bacterial-enhanced technique for decreased metal uptake of greens and improved vegetable and soil qualities in the metal-contaminated soils.

Biochar effects on soil biota – A review
Johannes Lehmann,Matthias C. Rillig,Janice E. Thies,Caroline A. Masiello,William C. Hockaday,David E. Crowley +5 more
TL;DR: A review of the literature reveals a significant number of early studies on biochar-type materials as soil amendments either for managing pathogens, as inoculant carriers or for manipulative experiments to sorb signaling compounds or toxins as mentioned in this paper.
Journal ArticleDOI
Some aspects of the surface chemistry of carbon blacks and other carbons
TL;DR: In this paper, a review of the surface chemistry of carbon blacks and other activated carbons is given, focusing on surface oxides with emphasis on the chemical methods used in the assessment and identification of surface functional groups.
Journal ArticleDOI
Ameliorating physical and chemical properties of highly weathered soils in the tropics with charcoal – a review
TL;DR: In this paper, the authors reviewed the available information about the physical and chemical properties of charcoal as affected by different combustion procedures, and the effects of its application in agricultural fields on nutrient retention and crop production.

Dynamic molecular structure of plant biomass-derived black carbon (biochar)
TL;DR: A molecular-level assessment of the physical organization and chemical complexity of biomass-derived chars and, specifically, that of aromatic carbon in char structures suggests the existence of four distinct categories of char consisting of a unique mixture of chemical phases and physical states.
