“…The length of the alkyl chain is one of the factors which have an important influence on the surfactant properties such as: solubility in water, critical micellar concentration or hydrophilic-lipophilic balance (Geetha and Tyagi 2012;Keck et al 2014 A c c e p t e d M a n u s c r i p t 3 of APG on bacterial cells and biodegradation processes can also be determined by molecular structure of these surfactants. The aim of this study was to investigate changes in cell surface properties of Pseudomonas fluorescens ATCC 14700 in the presence of three alkyl polyglucosides of different alkyl chain length: Glucopon 215 CS UP, Glucopon 600 CS UP and Glucopon 650 EC.…”

The use of surfactants in a bioremediation process is aimed at increasing the efficiency of the removal of hydrophobic contaminants from the environment. The subject of the study were three alkyl polyglucosides of different alkyl chain length: Glucopon 215 CS UP, Glucopon 600 CS UP and Glucopon 650 EC. The impact of these surfactants on the surface properties of the test strain Pseudomonas fluorescens ATCC 14700, as well as on the biodegradation of diesel was tested.It was observed, that the length of alkyl chain has an influence on the cell surface properties. The modification of the cell surface hydrophobicity and the electrokinetic potential on the bacteria cells is dependent on the structure of Glucopon molecules. The elongation of alkyl chains in surfactant molecule caused an increase of the hydrophobic properties and a reduction of the electrokinetic potential on the bacteria cells. Moreover, the use of alkyl polyglucosides below critical micelle concentration caused an increase of diesel oil biodegradation, especially in the case Glucopons with longer alkyl chain (Glucopon 600 CS UP and 650 EC). The better diesel oil removal by tested strain after surfactant addition was correlated with the hydrophobic properties of bacteria strain.

“…APGs are the ingredients of most of the biodegradable, non-ionic surfactant compounds found in dishwashing detergents, liquid detergents and special detergents for industrial cleaning operations. The use of such substances is ever more widespread due to their good foaming properties [20,21]. APGs consist on a hydrophobic alkyl chain and sugar hydrophilic derivatives.…”

Water resources are increasingly under pressure because of human activities and economic development. Moreover, accelerated urbanization and the expansion of drinking water supply and sanitation systems contribute to this rising demand. The development of water reuse solutions is an urgent issue. This study presents a solution for the reuse of wastewaters generated from floor cleaning operations of industrial or public areas. A portable device containing a grid, for coarse filtration, and a 300-L reaction chamber to carry out the sequential processes of coagulation, flocculation and settling, was employed for a field test. In the field test the wastewater coming from the tank of a cleaning machine, used for floor cleaning in an industrial site, was treated and reused for the same purpose for a total of 110 times. The quality of the treated wastewater was monitored cycle after cycle and the results of the test demonstrated that the treated water was suitable to be reused for the same purpose, even after a large number of cycles, provided that a finishing treatment was eventually supplemented in order to reduce the residual concentration of organic substances. It was demonstrated that, under standard operating conditions, that is a wastewater with a total suspended solid (TSS) content of 800 mg/L, and on the grounds of the results found in the test, that is a TSS removal efficiency of 98% and a sludge total solid (TS) content of 6%, the whole volume of the cleaning machine tank was completely renewed with fresh water after 60 cycles. Eventually, the combination of treatment and reuse operations allowed to save approximately 18,000 L of fresh water over a series of 60 cleaning cycles. The proposed treatment allowed not only to save fresh water but even to reduce the cost of water usage by approximately 50%. In fact, thanks to this treatment, the cost of a single cubic meter of water decreased from approximately 6 €/m3, which included supply of fresh water and discharge to the public sewer, to approximately 3 €/m3.

“…Fortunately, with respect to surfactants, the formation of mixtures of products and isomers is not an obstacle to their uses and applications, despite significant variations in their properties depending on their intimate structure. APGs exhibit very satisfactory safety for end users and excellent biodegradability, thus exhibiting no handicap with respect any environmental concern [47][48][49][50][51]. This is why APGs, alkyl polyglycoside could be developed with a real success, with first patents referring back to the 1930's, [52] and the unusual physicochemical behavior of long chain glucosides was even already mentioned back in 1911 by Fischer and Helferich [53].…”

Real industrial production started in the 1970s (Rohm & Hass) and have reached now a market close to 100 000 tons per year [47][48][49][50][51]. Main applications are uses in cosmetic and personal care formulations, in hard surface and laundry detergents, as adjuvants (notably for agrochemicals), with variations in properties depend essentially on the aglycone chain length.…”

GLOSSARY Carbohydrates are a family of biomolecules, ubiquitous in Nature, based on a common polyhydoxylated backbone though varying in size (from small molecules to macromolecules), in fine structure (configuration and functionalization), and possessing a wide range of biological properties and roles making them indispensable to life. Amphiphiles are molecular architectures with parts exhibiting different types of polarity, generally including hydrophilic and hydrophobic groups. Surfactants are molecules possessing the ability to modulate interfacial tension, notably water surface tension. Bio-based chemicals are chemical products which are obtained by transformation of a starting material arising from biomass, such as carbohydrates, fats, proteins, terpenes. DEFINITION OF THE SUBJECT Surfactants are commodity chemicals used in an incredibly wide range of situations of the everyday life, and must therefore be improved constantly in terms of environmental impact, sustainability and performance. One way towards more sustainable surfactants is the use of renewable resources as raw materials for their manufacture, in place of fossil ones. Since the structure of surfactant combines a polar part to a hydrophobic one, carbohydrates, which are very polar molecules, appear as ideal candidates for serving as renewable building blocks in the synthesis of bio-based surfactants. Developed first with the aim of providing added-value to some agricultural crops and by products, this strategy shows nowadays a rebirth in the context of green and sustainable chemistry. The chapter illustrates, from the chemical point of view, the diversity of molecular structures which belong to the family of carbohydrate-based surfactants.
