TL;DR: The diffusion characteristics of several substrates of varying molecular sizes into and from Ca‐ alginate gel beads in well‐stirred solutions were investigated and the capacity of Ca‐alginate Gel as a matrix of immobilization was discussed.

TL;DR: This study demonstrated that the use of gellan gum as a gelling reagent instead of agar was more effective at increasing culturability, cultivating a diverse array of novel microbes, and reducing the gaps of the results between molecular and cultivation-based analyses.

TL;DR: In this paper, an adsorbent for heavy metal was synthesized by introducing polyethyleneimine (PEI) into porous cellulose carriers, which showed the ability of cell-PEI to selectively remove mercury even at acidic regions.

TL;DR: In this paper, the effects of an anoxic period on N2O emission and nitrogen removal were investigated in an actual domestic wastewater treatment plant, and the results showed that an optimum combination of aerobic and anoxic conditions and their suitable control are very important for improving nitrogen removal efficiency and controlling N 2O emission.

TL;DR: The biological activities of 7 microbial extracellular glycolipids except for RL were found to induce cell differentiation instead of cell proliferation in the human promyelocytic leukemia cell line HL60, and the results showed that MEL-A, M EL-B, and PL induced HL60 to differentiate into granulocytes, while SL, STL-1, and STL-3 induced differentiation into monocytes.
