Abstract
Description
また更に、ナノバブルを用いて生物の生理活性に変化を及ぼす技術が注目されてきた。例えば特許文献2に、植物の成長を促進させるなどの目的で利用が可能な旨が記載されている。
従来は、気液混相流の中でファンを高速回転させる方法、気液混相流に高圧をかけて漏斗状の管に導入しキャビテーションを発生させる方法等が提案されてきたが、装置の構造が複雑になり、装置一台あたりの価格が高額になるため、ナノバブル技術を実施できる分野が限定されていた。
また、液相中でナノバブルを発生させていたため、液体により可動部が大きな抵抗を受けることとなり、多くのエネルギーを浪費し、経済性の観点から技術が実施できる分野が限定されていた。
従来は、負に帯電したナノバブルしか発生させることができず、こうしたナノバブルは、正に帯電したイオンや物質表面にしか結合しないため、技術が実施できる分野が限定されていた。
従来は、負に帯電したナノバブルしか発生させることができず、ナノバブルが生物に与える影響が、ナノバブル内に封入されたガスの影響によるものなのか、ナノバブルが有する負の帯電によるものなのか、それともナノバブルが物理的に衝突することによるものなのか、結論付けることが困難であった。
また本発明は、正及び負に帯電したナノバブルの微生物及び植物の生長に対する影響を明確化することを第2の課題とする。
また、前記帯電したナノバブル分散液は、正に帯電したことが好ましい。
また、本発明の帯電したナノバブル分散液製造装置は、請求項3又は4に記載の製造方法によって請求項1に記載のナノバブル分散液を製造することを特徴とする。
また、本発明の帯電したナノバブル分散液製造方法を用いて、ナノバブルの帯電性に依存する酸化剤又は還元剤を製造することができる。
しかしながら、本発明においては、ナノバブルを発生させる機構を気相内に置くことができるようになり、エネルギーの消費量が減少したため、技術を実施できる分野が大幅に拡がった。
また、正及び負の帯電を持つナノバブルを作り分けることが可能になったことにより、ナノバブルが物質に電子を付与又は受容する性質があることが明らかになった。
以下において、用いられたナノバブルは、気泡となる気体雰囲気中において、マイクロメーターサイズに微細化された液体を更に破砕することによって、前記液体に囲まれた帯電したナノバルブを生成させ、これを、重力、遠心力、電磁気力、等を用いて捕集することによって前記液体に帯電したナノバブル分散液を製造できる。
図1に、本発明の実施例1のプラスにナノバブルのゼータ電位とそのゼータ電位を有するバブルの頻度(ゼータビュー)を示し、図2に実施例2のマイナスに帯電したナノバルブのゼータビューを示す。
本発明の帯電したナノバブルは、陽イオン性物質または陰イオン性物質と結合又は乖離する物質を製造する方法を提供する。
また、本発明の帯電したナノバブルは、ナノバブルが電子を付与又は受容する性質を有することにより、水と空気のみから所要の酸化力又は還元力を持ち、一定時間後には分解される酸化剤及び還元剤を製造することが可能になった。
密閉した空気雰囲気中にマイクロメーターサイズに微細化された水を供給し、隣設する回転体同士が相互に反対方向に回転するよう設置された複数の回転体を用いてマイクロメーターサイズに微細化された水を更に破砕し、生成したミストを捕集することによって、水に囲まれプラスに帯電したナノバブルを得ることができた。得られたナノバブルの直径別密度及び電荷別密度をマイクロトラックベル社のナノバブル電荷測定を用い、ZetaView+T.Ohdaira 荷電ディスク法で計算して測定し、気泡の平均粒径は、兵庫県のSpring 9に設けられ、Omega Lenzを備えるUltra-high voltage electron microscopeを用いて測定した。
プラスに帯電したナノバブルの電荷別密度(ゼータビュー)を図1に示す。
密閉した空気雰囲気中に高電圧を印加してマイナス側を接地し、マイクロメーターサイズに微細化された水を供給し、隣同士が反対方向に回転し設置された複数の回転体を用いてマイクロメーターサイズに微細化された水を更に破砕し、生成したミストを捕集することによって、水に囲まれマイナスに帯電したナノバブルを得ることができた。図2に、帯電したナノバブルの電荷別密度を示す。
[実施例3]空気を封入したナノバブル用いた場合
野生型のクラミドモナス(NIES-2235株 Chlamydomonas reinhardtii.以下、単に「クラミドモナス」という。)を用い、空気を封入し正に帯電したナノバブルを含む培養液(プラス群)、負に帯電したナノバブルを含む培養液(マイナス群)、ナノバブルを含まない培養液(対照群)の3種類に分け、各群のクロロフィル生産量を測定した。
微生物学名(NIES株番号):NIES-2235株
培地:C培地(寒天もボトルも同じC培地)
購入元:国立研究開発法人国立環境研究所 微生物系統保存施設
・クラミドモナスを、平型シャーレを用いて,距離25cmの上面からシャーレ内の微生物に対し、光合成に最適とされる、620ナノメートルから630ナノメールの波長ピークを有する光を連続照射した。培地はHSM寒天培地を用いた。
・ナノバブル試料
プラス群、実施例1に記載した方法で、但し炭酸ガス中で正に帯電したナノバブルを用いて培地を製造した。
マイナス群、実施例2に記載した方法で、但し炭酸ガス中で負に帯電したナノバブルを用いて培地を製造した。
対照群、ナノバブルを含まない蒸留水を用いて培地を作成した。
・培養したクラミドモナスは一定時間おきにアセトンによるクロロフィル抽出法を用いて抽出し、得られたクロロフィルを分光光度計(NanoDrop社製:ND-1000)によって測定した。
・測定結果を図3に示す。
図3に示すように、プラス群は対称群と比較し、誘導期及び対数増殖期において増殖速度が有意に増加した。マイナス群は対称群と比較し、増殖速度が減少した。
実施例3と同様に、但しナノバブル試料のプラス群およびマイナス群を二酸化炭素ガス中で製造し、各群のクロロフィル生産量を測定した。
測定結果を図4に示す。実施例1と同様に、プラス群は対称群よりも速く増殖し、マイナス群は対称群よりも遅くなった。
実施例3と同様に、但し12時間の暗期を設けてクロロフィル生産量を測定した。
測定結果を図5に示す。
図5に示すように、プラス群は対称群よりも速く増殖したが、マイナス群は対称群と同様の増殖速度となった。
