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.

FEBS Letters, EarlyView.Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation
FEBS Letters, EarlyView.Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

Dynamic Modeling of Fouling in Reverse Osmosis Membranes
Membranes, 2021 During reverse osmosis (RO) membrane filtration, performance is dramatically affected by fouling, which concurrently decreases the permeate flux while increasing the energy required to operate the system.

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.

FEBS Letters, EarlyView.We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...
