Resistance to permeate flux in the filtration of methanogenic waste.

KAGAKU KOGAKU RONBUNSHU, 1988
セラミック膜をメタン発酵メンブレンバイオリアクターに適用するための濾過実験を行うに当たり, まず, 膜への供給液としてのメタン発酵液に含まれる浮遊固形物の特性を明らかにした.メタン発酵液は, グルコース-ペプトン系合成廃水をメタン発酵処理した物である.本液中の浮遊固形物はメタン菌とその代謝物より成りその大きさは, 球形粒子で直径 0.05μm 前後, 球菌で直径 0.2 から 1μm, 菌で径方向 0.2 から 0.7μm, 軸方向1から 2μm であった.これらの粒子を淵過した場合に膜面に形成される粒子充填層において, 粒子は濾過圧力で変形し, また, 比抵抗は塩濃度に支配されることがわかった. 比抵抗は塩濃度の上昇により増大した.この結果は DLVO 理論により説明できた.

Conserved binding mode but diverse interfaces of MreC‐PBP2 interactions

FEBS Letters, EarlyView.
The crystal structure of abMreC reveals a conserved two β‐barrel architecture and provides structural insights into its role within the bacterial elongasome. The abMreC–abPBP2 complex model identifies the molecular basis of MreC‐mediated PBP2 recognition, contributing to the regulation of peptidoglycan synthesis.

Evolution of Membrane Performance During the Ultrafiltration of Reactive Black 5 Solutions: Effect of Feed Characteristics and Operating Pressure

Chemical Engineering Transactions, 2012
In the present work, the feasibility of the ultrafiltration (UF) technology for the removal of a hazardous azo reactive dye, Reactive Black 5 (RB5), was studied. A tubular UF ceramic membrane was used to filter RB5 aqueous solutions.

Microbiome‐blood–brain barrier interactions in aging — mechanisms and therapeutic potential

FEBS Letters, EarlyView.
Aging reshapes the gut microbiome (↓SCFA‐producing commensals; ↑pro‐inflammatory outputs), shifting circulating metabolites (↓SCFAs; ↑LPS, ↑TMAO, ↑PAA) that act at the BBB to increase nonspecific transcytosis, alter transport, and promote astrocyte reactivity, heightening brain vulnerability.

Use of flocculants for increasing permeate flux in anaerobic membrane bioreactors

Water Science and Technology, 2014
Biomass retention, required for high rate anaerobic wastewater treatment, can be accomplished coupling an anaerobic bioreactor with membrane filtration. However, low flux seems to be a common factor when operating anaerobic membrane bioreactors (AnMBRs). Modification of biomass properties may represent a strategy for improving membrane flux.

Engineering peptides into antibodies—opportunities and strategies for therapeutic innovation

FEBS Letters, EarlyView.
Peptides and antibodies occupy complementary therapeutic niches. Peptides recognize difficult targets in a compact format, while antibodies add specificity, long half‐life, and effector functions. This review examines strategies that merge both modalities—peptide grafting into loops, terminal and Fc fusions, and bioconjugation—highlighting how ...
