“…High yield was obtained using 5 g/l of sucrose as carbon source. A much lower cost medium with high biomass productivity of this biocontrol agent was developed using byproducts from the carob industry (Manso et al 2010b), and from the citrus industry (Manso et al, unpublished data). Costa et al (2001) using another strain of P. agglomerans (CPA-2) optimized its production by using dry beer yeast as nitrogen source.…”

Postharvest decay in harvested fruit causes considerable economical losses. Fungicides are the primary means to control these losses. Public concern in food safety and environmental issues and the increase of pathogen resistant populations have enhanced the interest in developing alternative methods to fungicides to control postharvest fruit decay. During the last two decades a huge information and advances concerning the selection of antagonists, mode of action, different approaches to enhance biocontrol activity, formulation and production have been achieved, and some biofungicides are already in the market. It is likely that several more products will enter the market in the near future, as the result of the biological control research programs worldwide. Nonetheless, it is necessary to continue finding new potential microorganisms, better understanding the mode of action, and pathogen, antagonist and host interactions, to increase the potential of biocontrol helping to become a real alternative to synthetic postharvest fungicides. This article presents an overview of postharvest biological control approaches and explores new research possibilities to improve biocontrol activity.

“…Broccoli byproducts may be used as a source of bioactive ingredients to design novel beverages-using organic green tea as a food matrix-presenting improved physical quality, phytochemical composition and antioxidant capacity (Dominguez-Perles et al, 2011). Carob pulp aqueous extracts were used as carbon source in the production of the biocontrol agent Pantoea agglomerans PBC-1, usable as bio-pesticide (Manso et al, 2010). Tests proved that the aqueous extracts exhibit a high potential of this by-product as a carbon source to produce high amounts of biomass of the biocontrol agent at low cost.…”

The production of food waste covers all the food life cycle: from agriculture, up to industrial manufacturing and processing, retail and household consumption. In developed countries, 42% of food waste is produced by households, while 39% losses occur in the food manufacturing industry, 14% in food service sector and remaining 5% in retail and distribution. Increasingly, industrial ecology concepts such as cradle to cradle and circular economy are considered leading principle for eco-innovation, aiming at "zero waste economy" in which waste are used as raw material for new products and applications. The large amount of waste produced by the food industry, in addition to being a great loss of valuable materials, also raises serious management problems, both from the economic and environmental point of view. Many of these residues, however, have the potential to be reused into other production systems, trough e.g. biorefineries. The present work focuses on the use of food waste coming from food manufacturing (FWm). Through extensive literature review, the authors present feasibility and constraints of applying industrial symbiosis in recovering waste from food processing, focusing on recycling (excluding energy recovery) of the solid and liquid waste from food processing industry. The main uses of functional ingredients derived from this transformation are presented and discussed, highlighting mainstream sectors of application, e.g. in the nutraceutical and pharmaceutical industry.

“…Up to four leaching tests were conducted, with half initial ratio, to take full advantage of all soluble sugars in the carob pulp. These mixtures were homogenized at 150 rpm, 25°C for 1 h as suggested by Manso et al [10,11]. After this period, to clarify the carob pulp extract, the mixtures were centrifuged at 7,500g, at 4°C for 15 min (Beckman J2-MC Centrifuge with a JA14 rotor), filtered through a 0.22-lm membrane filter, and stored at -20°C.…”

“…Its price has fluctuated and is about 200 €/ton. The carob seeds represent 10% of the weight of the fruit and the pulp represents the other 90% [10]. Several authors have reported that carob pulp composition has a high content of sugars, mainly sucrose (more than 30%), fructose, and glucose with values of 20-50% [15], 45% [2], 48-56% [22], and 28-82% [4].…”

“…This gave economical relevance to carob pulp as an inexpensive and available feedstock for various biological products, e.g., dextran and fructose [18], citric acid [17], and ethanol [16]. The by-products from the carob processing industry are small carob kibbles, which contain a high content of sugar (mainly sucrose, glucose, and fructose) which are easily extractable by water, producing sugar-rich syrups [10].…”

The waste materials from the carob processing industry are a potential resource for second-generation bioethanol production. These by-products are small carob kibbles with a high content of soluble sugars (45-50%). Batch and fed-batch Saccharomyces cerevisiae fermentations of high density sugar from carob pods were analyzed in terms of the kinetics of sugars consumption and ethanol inhibition. In all the batch runs, 90-95% of the total sugar was consumed and transformed into ethanol with a yield close to the theoretical maximum (0.47-0.50 g/g), and a final ethanol concentration of 100-110 g/l. In fed-batch runs, fresh carob extract was added when glucose had been consumed. This addition and the subsequent decrease of ethanol concentrations by dilution increased the final ethanol production up to 130 g/l. It seems that invertase activity and yeast tolerance to ethanol are the main factors to be controlled in carob fermentations. The efficiency of highly concentrated carob fermentation makes it a very promising process for use in a second-generation ethanol biorefinery.
