Article Synopsis
  • This research explores the antimicrobial properties of total phenolic compounds (TPC) and exopolysaccharides (EPS) from cryptophytes against harmful bacteria and fungi.* -
  • The study found that TPC demonstrated stronger antibacterial and antifungal activity than EPS, with minimum inhibitory concentration (MIC) values generally lower for TPC.* -
  • Both TPC and EPS showed a bactericidal/fungicidal mechanism of action, suggesting their potential use as natural preservatives in the food industry.*

Article Synopsis
  • Heart failure (HF) is a major health issue for those over 65, and seismocardiography, which measures heart vibrations through the chest, is being explored as a noninvasive detection method.
  • A multicenter study involving both inpatient and outpatient participants in Finland and the U.S. found that smartphone-based seismocardiography can effectively distinguish HF patients from healthy controls using advanced algorithms.
  • The study involved 217 HF patients and 786 control subjects, achieving high accuracy rates (89%) for HF detection, regardless of factors like age and sex.

Nanocellulose is isolated from cellulosic fibers and exhibits many properties that macroscale cellulose lacks. Cellulose nanocrystals (CNCs) are a subcategory of nanocellulose made of stiff, rodlike, and highly crystalline nanoparticles. Algae of the order Cladophorales are the source of the longest cellulosic nanocrystals, but manufacturing these CNCs is not well-studied.

Iron is one of the important micronutrients affecting algal growth due to its fundamental role in the physiological processes, including photosynthetic electron transport, respiration, and nitrogen fixation. In this study, the effect of different iron levels on growth and the production of bioactive compounds (phycoerythrin (PE), extracellular polymeric substances (EPS), and phenolic compounds (PCs)) of five cryptophyte strains were investigated. Also, the antioxidant capacity of the bioactive compounds was explored.

Chemotaxonomic biomarkers are needed to monitor and evaluate the nutritional quality of phytoplankton communities. The biomolecules produced by different phytoplankton species do not always follow genetic phylogeny. Therefore, we analyzed fatty acids, sterols, and carotenoids from 57 freshwater phytoplankton strains to evaluate the usability of these biomolecules as chemotaxonomic biomarkers.
