福井県にある北潟湖を対象に水生植物を利用した水質浄化と資源循環について検討した。10月のヨシおよびマコモの刈り取りは、流入量に対し窒素1.1%、リン1.9%の排出量と推定され、水質への影響は小さいと考えられた。一方、これら水生植物のバイオガス化と堆肥化は、副次的な原料として十分可能であると思われた。また、エタノール発酵のための硫酸を用いた前処理を検討し、ヨシ中セルロースの50%をグルコースに転換できる条件を見出した。

紙、木、わら、もみがら、ヨシ、マコモおよび雑草2種類のメタン発酵性を回分式バイアル試験によって調べた。メタン転換率は最大が紙の87%、最小がもみがらおよびマコモの25%となり、これらの未利用植物系バイオマスはメタン発酵の副次的な原料として使用できると考えられた。

グルコースを基質とした高温および中温メタン発酵において、必須微量金属である鉄、ニッケル、コバルトおよび亜鉛の最小必要量はそれぞれ高温で0.45、0.049、0.054、0.24、中温で0.20、0.0063、0.017、0.049 mg/g除去CODと求められた。高温メタン発酵の方が数倍（2.2～7.8倍）多く必要であり、これは摂取量の多さあるいはバイオアベイラビリティーの低さを示すものと考えられた。
