Biochar is a carbon-rich charcoal-like substance obtained by heating biomass in limited oxygen condition, through a process known as pyrolysis. If biochar is buried into the soil for carbon credits and crop enhancement, then the pyrolysis process can be carbon negative. When the process of producing biochar sequesters more carbon than it emitted, it is carbon negative.Full Text

Highly arsenic-polluted soil (16.5 mg kg–1) of West Bengal, India, was used for isolation, screening and identification of indigenous soil microbes. Citrobacter koseri significantly removed (7.6) and bioaccumulated (4.95) highest arsenic in P15As15 treatment, while loss (2.9) was higher in P10As15. Similarly, Pseudomonas putida significantly removed (7.4) and bioaccumulate (4.8) highest as in P15As15 and while loss (2.8) was higher in P10As15. Percentage removal of As was 47–59, bioaccumulation was 29–38 and loss 17–23 with Citrobacter sp., while it was 47–58% (removal), 29–39% (bioaccumulation) and 17–21% (loss) with Pseudomonas putida. Maximum removal and bioaccumulation of phosphorus was 37.8% and 32.1% respectively, for P10As15 in Citrobacter sp. In P. putida it was 33.1% and 27.2% respectively, for P10As15. At the same level of arsenic, increase in phosphorus significantly increased its removal and bioaccumulation, but the opposite was true during calculation in terms of percentage removal and percentage bioaccumulation.Keywords
