  • Microplastics in the wastewater treatment plants (WWTPs): Occurrence and removal. [Journal Article]
    Chemosphere 2019; 235:1089-1096Xu X, Jian Y, … Wang L
  • WWTPs may be one of the important ways for MPs to enter surface water. In the present study, the influent and effluent from eleven WWTPs in Changzhou were collected and analyzed. At the same time, the abundance, size, color, and shape of MPs in influent and effluent were investigated. The average abundance of MPs in the influent and effluent were 196.00 ± 11.89 n/L and 9.04 ± 1.12 n/L respectivel…
  • Microplastic contamination in Penaeid shrimp from the Northern Bay of Bengal. [Journal Article]
    Chemosphere 2020; 238:124688Hossain MS, Rahman MS, … Nawaz Chowdhury MS
  • Microplastic pollution has received increased attention recently due to potential threat to marine biota and human health. This study reports microplastic (MP) content in brown shrimp (Metapenaeus monocerous) and tiger shrimp (Penaeus monodon) inhabiting in the shallow and offshore waters of the Northern Bay of Bengal, Bangladesh. Gastrointestinal tract (GT) of shrimps (n = 150) were examined for…
  • Recycling of viscose yarn waste through one-step extraction of nanocellulose. [Journal Article]
    Int J Biol Macromol 2019; 136:729-737Prado KS, Gonzales D, Spinacé MAS
  • Textile manufacturing industries generate large amounts of viscose yarn waste (VW) that causes serious environmental pollution. In this study, VW was used as raw material to successfully extract nanocellulose (NC) in a facile one-step extraction process, without any pretreatment. Different hydrolysis reaction times (5-60 min) were employed, and the extracted material was characterized by Fourier …
  • [Industrial and Medical Material Applications of a Mega-polysaccharide Derived from Cyanobacteria]. [Review]
    Yakugaku Zasshi 2019; 139(3):363-369Okajima M, Kaneko T
  • Polysaccharides (PS) are one form of biomass occurring in great abundance on earth and are promising organic material alternatives to petroleum-based ones. We have focused on PS produced by cyanobacteria. Aphanothece sacrum, which is a freshwater unicellular cyanobacterium, produces large amounts PS as a main component of the extracellular matrix. We successfully extracted the PS sacran from A. s…
  • Microbial production of high value molecules using rayon waste material as carbon-source. [Journal Article]
    N Biotechnol 2019; 51:8-13Vecchiato S, Skopek L, … Guebitz GM
  • Rayon filaments composed of regenerated cellulose are used as reinforcement materials in tires and to a lower extent in the clothing industry as personal protective equipment e.g. flame retardant cellulosic based materials. After use, these materials are currently transferred to landfills while chemical degradation does not allow the recovery of the cellulose (as glucose) nor the separation of th…
