2. 1. Regulation of productivity in Trichoplusia ni and Spodoptera frugiperda Sf9 serum-free cultures

   Author : Karin Calles; Lena Häggström; Gunnel Dalhammar; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biotechnology; Insect cells; BEVS; Spodoptera frugiperda; Sf9; Trichoplusia ni; BTI-Tn-5B1-4; specific productivity; conditioned medium; conditioned medium factors; cell cycle; synchronization; G2 M; Bioteknik; Bioengineering; Bioteknik;

   Abstract : The aim of this work has been to characterize the effects of conditioned medium (CM) on insect cell productivity and physiology in order to get a better understanding about the mechanisms that regulate productivity in serum-free media. Two cell lines have been investigated, Spodoptera frugiperda (Sf9) and Trichoplusia ni (T. ni, BTI-Tn-5B1-4). READ MORE

4. 2. Physiological effects of conditioned medium and passage number on Spodoptera frugiperda Sf9 serum free cultures

   Author : Ingrid Svensson; Lena Häggström; Mats Martinelle; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biotechnology; Spodoptera frugiperda Sf9; insect cell cultures; conditioned medium; cell cycle phase dynamics; proteolytic activity; antibacterial activity; recombinant protein production; Bioteknik; Bioengineering; Bioteknik;

   Abstract : The aim of this study was to better understand the role of conditioned medium (CM) in Spodoptera frugiperda Sf9 insect cell proliferation and recombinant protein production using the baculovirus expression system. CM was found to stimulate cell proliferation. READ MORE

6. 4. Physiology and productivity of serum-free Spodoptera frugiperda Sf9 insect cell cultures

   Author : Eva Lindskog; Lena Häggström; Spiros N. Agathos; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Animalcellteknologi; Bioengineering; Bioteknik;

   Abstract : The objective of this study was to investigate the mechanisms and factors controlling growth and proliferation in serum-free Spodoptera frugiperda Sf9 cultures as well as the implications of these factors for protein production in the baculovirus expression system. The physiology of recently thawed, low passage (Lp) Sf9 cultures, were compared to high passage (Hp) cultures at p>100. READ MORE

7. 5. Revisiting push-pull technology: Below and aboveground mechanisms for ecosystem services

   Author : Aneth Bella David; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

   Abstract : Push-pull technology is an effective and ecological solution to suppressing major Lepidopteran pests of cereals, in particular stem-borers (Busseola fusca, Chilo partellus), the fall armyworm (Spodoptera frugiperda) and the parasitic weed Striga. The technology exploits plant-insect interactions in intercropping practices to manage the pests, increasing productivity while maintaining ecosystem resilience. READ MORE
