Purpose: Nosemosis is a disease that infects both Western honeybees (Apis mellifera L.) and Asian honeybees (Apis cerana) and causes colony losses and low productivity worldwide. In order to control nosemosis, it is important to determine the distribution and prevalence of this disease agent in a particular region.

Article Synopsis
  • Biosorptive treatment with immobilized microbial biomass, specifically using maize tassel tissues with fungal cells, presents an eco-friendly method for removing dye contamination from water sources.
  • The research achieved high biosorption yields of 95.7% in batch tests and 90.0% in dynamic flow tests for Reactive Yellow 2 (RY2) within just 60 minutes, suggesting effective and rapid decolorization.
  • The study confirms that this approach doesn’t create secondary pollution and estimates the cost of producing the biosorbent at approximately 61.03 USD/kg, making it a sustainable and viable option for water treatment.

A novel biomaterial was prepared by the immobilization of Phlebia gigantea cells in the medium containing lignocellulosic waste and used for the first time in the bioremediation purpose. The developed new biocomposite possesses higher Pb(II) retention potential when compared with the free microbial cells. It could remove Pb(II) up to 74.

A novel biomass/polymer composite was fabricated by embedding Thamnidium elegans cells in acrylic network of p(3-Methoxyprophyl)acrylamide p(MPA) enriched with 2-Akrylamido-2-methyl-1-propane sulfonic acid (AMPS). Cd(II) retention potential of hydrogel (p(MPA-co-AMPS)) increased by 20.66% times after this enrichment.

Biosorption is an effective alternative method for the control of water pollution caused by different pollutants such as synthetic dyes and metals. A new and efficient biomass system was developed from the passively immobilized fungal cells. The spongy tissue of Phragmites australis was considered as the carrier for the immobilization of Neurospora sitophila cells employed for the biosorption of Basic Blue 7.

This study focused on the improvement of the decolorization potential of biomass derived from Pyracantha coccinea. Alkyl benyzldimethyl ammonium chloride (ABDAC) was used as modification agent. Batch mode decolorization potential of modified biosorbent was explored at different operating conditions.
