Published: July 2006

Laboratory investigations of the potential use of dried biomasses of Rhizopus stolonifer, Fusarium sp., Geotrichum sp., and Aspergillus fumigatus as biosorbents for the removal of bromophenol blue (BPB) dye from aqueous solutions were conducted. Kinetics studies indicated that the BPB dye uptake processes can be well described by the pseudo-second-order model. The fungal biomasses exhibited the highest dye biosorption at pH 2.0. The Langmuir adsorption model appears to fit the dye biosorption better than the Freundlich model, with maximum dye uptake capacities ranging from 526 to 1,111 mg/g, depending on the biomass used.

Laccase is an extracellular enzyme that is widely used in the decolonization of textile dyes in waste water. The aim of our study was to isolate, purify, characterize and immobilize the laccase enzyme produced by HBB 7328. Purified laccase enzyme was immobilized in polyacrylamide gel to explore its ability in decolonization of textile dyes.

An efficient manufacturing of colorimetric nonwoven indicators represents a promising alternative to enable applications of such materials in food quality monitoring. The objective of this study is to use the solution blow spinning technique (SBS) to rapidly produce colorimetric nonwoven indicators based on polycaprolactone, incorporating natural or synthetic pH indicators to detect volatile amines, bacterial growth and monitor pH. Produced via the SBS method, these indicators were characterized aiming their physical, mechanical, thermal, and spectroscopic properties, evaluating their efficacy in detecting amines, monitoring bacterial growth, and pH, as well as assessing color stability during storage.

Nowadays, there is a need to expand the bank of spectrophotometric methods for the determination of perindopril in dosage forms for the purposes of routine pharmaceutical analysis, which would be simple, express, «green» and inexpensive. In the present work, perindopril in tablets was quantified via a direct simple, «green», and non-extracting spectrophotometric approach based on the formation of ion-pair complexes with sulphophtalein dyes. The absorbances of the colored reaction products were registered at 405 nm (bromocresol green, BCG), 397 nm (bromocresol purple, BCP, and bromothymol blue, BTB) and 598 nm (bromophenol blue, BPB).

Article Synopsis
  • Arginine (Arg) is a safe amino acid that improves the interactions and quality of myofibrillar proteins (MP) in meat products.
  • This study examined how different concentrations of Arg (0.025 to 0.200%) affect the properties and gel behavior of yak MP.
  • Results showed that 0.05% Arg significantly reduces oxidative damage and enhances water retention and gel qualities in MP, demonstrating its potential as a valuable additive in meat processing.

Two -symmetric acylhydrazone-based AIE active probes, TRI-QUI and TRI-NAP, were synthesized with different peripheral substituents. The probe containing a quinoline moiety in the periphery displayed a selective turn-on response towards Zn in HEPES buffer, with a calculated detection limit of 6.45 μM.
