Early-stage anaerobic zone formation by organic eluate from wood in soil

open access: yesSoils and Foundations, 2022
When separated soil (SS) generated from the Great East Japan Earthquake, which contains woodchips and others (WC), is utilized as ground material, microorganisms decompose the organic carbon in WC, and oxygen is consumed in the process.

Biotechnological aspects of sulfate reduction with methane as electron donor [PDF]

open access: yes, 2010
Biological sulfate reduction can be used for the removal and recovery of oxidized sulfur compounds and metals from waste streams. However, the costs of conventional electron donors, like hydrogen and ethanol, limit the application possibilities.

An Experimental Study of Microorganic Aerobic and Anaerobic Decomposition of Seaweed

open access: yesJournal of the Japan Society of Waste Management Experts, 1993
海岸に打ち上げられた代表的な海藻を高さ80cm, 直径25cmの塩化ビニール製およびガラス製のカラムに充填し, 好気性および嫌気性分解に関する基礎的実験を行なった。実験は週1回カラムに蒸留水と海水を1.5l入れ, 出てきた浸出水の観測および分析結果から分解特性を把握した。さらに, 分解条件を検討するため, 各種栄養塩を添加してバッチ式で培養実験を行なった。その結果は次のとおりであった。(1) 実験を開始した当初は, 微生物の分解活性が高く浸出水のTCとBODは高濃度であった。(2) 好気性分解は嫌気性分解と比べて浸出水のTOCは低いが, TCは高く, 分解率も高かった。(3) 海藻の分解には好塩性細菌であるVibriosp.やPseudomonassp.等の菌種が関与し ...
