The flocculation dynamics of algal cultures using alum and aqueous seed extracts as flocculants were analyzed through light scattering and fractal analysis. Floc growth in continuously stirred suspensions, with cell densities ranging from 200 to 800 μg L chlorophyll (Chl ), exhibited distinct patterns in fractal dimension () evolution relative to floc size: a smooth, monotonic increase; stochastic increase; and stabilization or leveling off. values ranged from 1.

This study presents a novel liquid chromatography-tandem mass spectrometry (LC-MS/MS) method for quantifying cabotegravir (CAB) in rat plasma. A novel, sensitive, and rapid LC-MS/MS method has been developed and validated. Furthermore, protein precipitation technique allowed us to lowered the limit of quantification (LOQ) to nanogram levels, allowing detection of smaller CAB amounts in plasma samples.

The recyclability of cellulase enzymes using zeolite and polyethylene glycol (PEG) was investigated. The cellulase enzymes from cellulose hydrolysate suspensions were adsorbed onto zeolite-β under typical working conditions (pH 5). PEG having a molecular weight of 200 Da and 20 kDa was used as an eluent to desorb the cellulase enzymes from zeolite-β.

Article Synopsis
  • Reject fines, a byproduct from paper recycling, are rich in cellulose and can be enzymatically converted into fermentable sugars for bacterial bioproduction.
  • The study found that using hydrolyzed reject fines as a carbon source significantly improved yields of poly(-3-hydroxybutyrate) (PHB) and poly(γ-glutamic acid) (PGA) compared to traditional purified sugars.
  • This approach not only enhances biopolymer production but also helps reduce environmental waste by turning a waste stream into valuable materials, making it a cost-effective and sustainable option.
