Current state of chitin purification and chitosan production from insects

open access: yesJournal of Chemical Technology &Biotechnology, Volume 95, Issue 11, Page 2775-2795, November 2020., 2020
Abstract Chitin, and especially its deacetylated variant chitosan, has many applications, e.g. as carrier material for pharmaceutical drugs or as a flocculant in wastewater treatment. Despite its versatility and accessibility, chitin, the second most abundant polysaccharide on Earth, has so far been commercially extracted only from crustaceans and to a

Species‐level image classification with convolutional neural network enables insect identification from habitus images

open access: yesEcology and Evolution, Volume 10, Issue 2, Page 737-747, January 2020., 2020
Species identity can be inferred from simple images of an extensive and highly accurate carabid beetle collection. Such image classification will be instrumental in efforts to increase the rate at which crucial occurrence data for insects are generated in the future.
