Can we engineer life? 2.3 Precision modification of the genome
Gene technology is a much-discussed technology with almost endless opportunities. Opponents have objected to it right from the start. Their worry was and is, that researchers do not exactly know what they’re doing when they adjust genes and modify the genome, where they’re doing it, and what the consequences might be. Opponents look upon gene
Innovative solutions for small farmers and organic farming
Mycorrhiza fungi increase yields in a targeted and environmentally friendly way, robots help farmers to control weeds ecologically. Smallholders optimise outputs with sensors in the soil and with modern biorefineries. Both smallholder and organic farming can benefit greatly from technological developments and innovative solutions while holding on to their ideals. Nova-Institute organizes the ‘Revolution in
Bio-based solvents on the rise
Driven by government regulations and concerns regarding environmental preservation and depletion of natural resources, the bio-based solvents industry has faced an exponential rise in demand and a push towards the development of innovative green solutions. These solvents, among which bio-acetone and bio-ethanol, are an effective and low-cost alternative to conventional solvents. Solvents are a vital
Can we engineer life? 2.2 Development of recombinant-DNA technology
In 1973, Stanley Cohen and Herbert Boyer of Stanford University and University of California, did the first successful recombinant-DNA experiments on the bacterium Escherichia coli. Through genetic ‘cutting and pasting’ they succeeded in introducing resistance in this bacterium that inhabits our guts, to two antibiotics, tetracycline and kanamycine.

Energy saving materials inspired by lizard skins and bark bugs
Imitating nature’s engineering secrets at the nanoscale could lead to a host of useful applications, like energy saving materials. Biomimicry, also called bionics, uses structures found in nature to solve everyday problems. A well-known example is the Velcro strip, which a Swiss engineer, Georges de Mestral copied from the burdocks that stuck to his dog
Microcrystalline cellulose: versatile and effective
Among the wonderful new materials with unexpected properties that will change our world is microcrystalline cellulose. I got a new perspective on it through the lecture of Stéphane Laurent at the Siñal exhibition in Châlons-en-Champagne, end May. Microcrystalline cellulose (MCC) is a relatively recently developed material with many applications. Production from cellulose MCC is a
Can we engineer life? 2.1 From evolution to revolution
Only quite recently historically speaking, mankind acquired the know-how to change the properties of living species: as people settled and developed agriculture. But it required a revolution, much later, to develop the knowledge to do this in a purposeful way. Hans Tramper is professor emeritus in Bioprocess Technology at Wageningen University and reflects on the
