Pullulans produced from the Aureobasidium pullulans fermentation of various agro-industrial wastes were characterised in terms of carbohydrate analysis. heterogeneity and molecular weights. Grape skin pulp extract (GSPE), starch waste (SW), olive oil waste effluents (OW) and molasses (M) were used as substrates for the production of pullulan. A glucose based defined medium (D) was used for comp...

Motivated by the negative impact of fossil fuel consumption on environment, need arises to produce materials and energy from renewable sources. Cellulose, main biopolymer Earth, plays a key role in this context, serving as platform for development biofuels, chemicals novel materials. Among latter, micro- nanocellulose have been receiving increasing attention last few years. Their many attractiv...

Olive pomace is a biowaste rich in polyphenols and insoluble dietary fibre with high potential to develop new value chains towards sustainable circular bioeconomy. Regarding gut health, olive phenolics (after possible fermentation) could act as antioxidants, antimicrobial prebiotic agents. These beneficial effects on the were analysed for two powders from pomace: liquid-enriched powder (LOPP) -...

The role of fruit bearing percentage in olive fruit fly infestation is investigated through a simulation model where the spatial law of dispersion distances were modeled via an appropriate exponential law. The dispersal of olive fruit flies was simulated for two distinct cases, an olive grove with no olive fruits and an olive grove with 100% olive fruit bearing. Results showed that when no oliv...

‘Arauco’ forms part of the over two thousand olives (Olea europaea L.) varieties identified worldwide with peculiarity being only recognized variety from Argentina. In this work, fruit and oil characteristics cultivated in three main olive growing zones Mendoza province (Argentina) were evaluated harvests (2016 2017). The assessed water concentrations, pulp/pit ratio, industrial yield, oxidativ...

The olive fruit fly, Bactrocera oleae (Rossi), is an economically important and endemic pest in olive (Oleae europae) orchards in Turkey. The aim of this study was to determine olive fruit fly infestation in different olive cultivars in the laboratory. Olive fly infested fruits were collected in Çanakkale province to establish wild fly population. After having reproductive olive fly colonies, 1...

A prospecting campaign in the Maltese Islands has ensured survival of several ancient olive trees (Olea europaea L.), genetically distant from known cultivars. Most these plants were abandoned or partially cultivated. two-year evaluation fruit characteristics and compositions was performed on samples collected main representatives indigenous genotypes. Analyses carried out using Gas Chromatogra...
