Structural classes relevant to a future bioeconomy are glycolipids and lipopeptides, which receive specialattentioninthisvolume.Assuch,thisvolumefocusesonthesemicrobially andenzymaticallyproducedbiosurfactantsofindustrialbiotechnology. Onereasonfortheincreasingresearchinterestinbiosurfactantsistheundeniable warming of the earth’s climate and the finite nature of fossil resources. In general, this has led to increased use of renewable raw materials as carbon sources in the chemicalindustry.Inthiscontext,theslowbutsteadyparadigmshiftinrecentyears has brought to light the need to replace the substrates previously used for biosurfactant production, especially glucose and vegetable oils that compete with food,withnewbioeconomicsubstrates,especiallywoodsugars. Inaddition,consumerdemandforsustainableandcarbon-neutralproductsisalso drivingtheneedtoreplacepetrochemicallyproducedchemicalswithbiochemically producedalternativesbasedonrenewableresources.Alreadytoday,somemicrobial surfactants, namely the glycolipids, mannosylerythritol lipids, rhamnolipids, sophorose lipids, and the lipopeptide surfactin are commercially available on an industrial scale. It is foreseeable that screening and synthetic biology will lead researchintonewcommerciallyrelevantbiosurfactants,whichwillincludedesigner biosurfactants. It is anticipated that bioproduction of microbial surfactants will bring increased efficiency in the future through metabolic engineering and new bioprocesses to be developed for in situ product separation, ensuring economic competitiveness in an increasing number of applications. Biosurfactantsserve these requirements in their entirety.Surfactants,ingeneral,areamongthehighestvolumechemicalsandtodate have been produced by petrochemical or oleochemical routes. In both cases, envi- ronmental andclimate issues are evidentdueto theuseof fossil carbon ortropical palmoil,respectively. v vi Preface Biosurfactants,however,offeradditionaladvantagesbesidessurfaceactivity.As a rule, biosurfactants exhibit specific bioactivities against fungi and other agricul- tural pests. Here, it is important to further explore and implement this potential as biopesticides.

In Europe a turnover of 60 billion EUR is associated with bio-based plastics and chemicals such as biosurfactants, and 40% of the global biosurfactant market turnover is associated with theEuropean market. The growing useofbio-basedsurfactantsindetergents, personal care products, and oilfield chemicals is fueling the growth of this market, which is driven, in many applications, by more stringent regulations and by an increasing consumer demand for “green and sustainable” products. Microbial biosurfactants are a biologically produced type of bio-based surfactants which are quicklyevolvingfromascientificcuriositytoanindustrialreality.

Together this has resulted into a new and growing movement toward the development of a bio-based economy providing an alternativeforthefossil-basedeconomy.Thefeedstockusedinthebio-economyis “biomass,” which – in contrast to fossil feedstocks – is a renewable feedstock derivedfromlandandsea:i.e.,fromplants,algae,animals,fungi,andmicroorgan- isms.Withinthebio-economy,morespecificallywithinthebio-basedindustries,this biomass feedstock is converted into the so-called bio-based products including biochemicals(e.g.biosurfactants),bioplastics,pharmaceuticals,paper,forest-based industries, textiles, biofuels, and bioenergy using both chemical and biological productionmethods.Thepercentageofbio-basedcarboninchemicalsandchemical products produced in the EU-28 – excluding biodiesel and bioethanol (NACE division 20) – corresponded to 15% in 2017. Surfactants are a class of chemicals that fall under the abovementioned category of chemicals and a big portion of the carbon used to produce surfactants is already derived from biomass (i.e., oleochemicals) while about 4% of the globally produced surfactants are fully bio-based [1]. The bio-economy (see Fig. 1) in the EU-28 was characterized by a turnover of 2.4 trillion EUR in 2017 of which 20% is associated with the primary sector producing the biomass feedstock, i.e. agriculture, fishery, forestry, etc. and 50% by its main downstream markets, i.e. the food and beverage industries. The remaining30%oftheoverallEuropeanturnover(750billionEUR)isgeneratedby the abovementioned “bio-based industries” of which 60 billion EUR turnover is associated with bio-based chemicals and plastics under which category bio-based surfactantsalsofall.
