Forming and maintaining stable aerobic granular sludge (AGS) at a low superficial gas velocity (SGV) is challenging, particularly with polymeric substrates. This study cultivated filamentous aerobic granular sludge (FAGS) with filamentous Kouleothrix (Type 1851) at low SGV (0.15 cm/s) utilizing mixed acetate-soluble starch.

- Two experiments on composting examined how commercial microbial agents affect microbial growth and nutrient distribution during the composting of spent mushroom substrate (SMS).
- The addition of these agents significantly improved cellulose degradation, with a rate of 41.8% compared to just 14.9% in the control group, and also enhanced seed germination index and reduced carbon to nitrogen ratio.
- The microbial agents increased bacterial abundance and sped up organic matter decomposition, leading to higher quality compost, contributing to better waste management and sustainability practices in the edible fungi industry.
Article Synopsis
- Methyl-modified, cobalt-doped silica (Co/MSiO) materials were created using a sol-gel technique and characterized to study the impact of cobalt on their structures and properties.
- The presence of cobalt results in a variety of bonds and crystal forms, leading to increased pore volume and size, which enhances gas permeance and selectivity compared to standard silica membranes.
- Testing under heat and steam conditions showed that Co/MSiO membranes maintained their performance better than MSiO membranes, demonstrating improved stability and efficiency in gas separation applications.
In practical application, the adsorption capacity, adsorption kinetics, recycling and production cost of adsorbent affect the application of adsorbent. In this study, porous lignosulfonate/chitosan adsorbent was prepared by simple radical polymerization of acrylic acid in the mixed solution of lignosulfonate and chitosan. The porous and large surface area of adsorbent provides more adsorption sites for heavy metal ions.

Its thermal stability and microstructure calcined under N₂ atmosphere were characterized by X-ray diffraction, X-ray photoelectron spectroscopy, Fourier transform infrared spectroscopy, scanning electron microscopy, transmission electron microscopy and N₂ sorption-desorption measurements. Pd element in Pd/SiO₂ gel material exists in PdCl₂ form, calcination at 350 °C can result in the complete transformation of Pd to metallic Pd.

Benefiting from the amphiphilicity, mPEG-PMMA-SS could self-assembled into core cross-linked micelles in aqueous medium with tunable sizes (85-151 nm), appropriate zeta potential (-24.8 mV), and desirable critical micelle concentration (CMC) (0.
