This study was conducted in quails to evaluate the probiotic potential of Pichia pastoris X-33, cultivated in parboiled rice effluent supplemented with biodiesel glycerol or in standard medium Yeast Extract–Peptone–Dextrose (YPD). Forty-days-old female quails were divided into three treatments: T1 (Control) received a basal diet without P. pastoris; T2 (Pichia Effluent) received a basal diet supplemented with P. pastoris grown in parboiled rice effluent and biodiesel glycerol, and T3 (Pichia YPD) received a basal diet supplemented with P. pastoris produced in YPD. The birds were vaccinated against Newcastle Disease (NDV), Avian Infectious Bronchitis (IBV), and Gumboro Disease on days 1 and 28. The following parameters were analyzed: performance, egg quality, humoral immune response to the vaccines, organ weight, and intestinal morphometry. P. pastoris grown in YPD increased egg weight (p < 0.05). The lowest liver weight on day 14 was obtained in Pichia Effluent, whereas both P. pastoris supplemented groups had the lowest duodenum weights on day 14. Besides that, livers and duodenums presented no morphological changes in any of the three treatments. Supplementation of P. pastoris modulated the immune system of the birds, increasing anti-IBV, anti-NDV, and anti-Gumboro antibodies levels compared to the Control (p < 0.05). In conclusion, quail’s immune response was improved by Pichia pastoris X-33, either it was grown in YPD or industrial residues, and the egg weight increased with Pichia pastoris X-33 grown in YPD, thereby demonstrating to be a promising probiotic for poultry.

“…In addition to their sugars resource and moderately long conservation period, dates offer many other technological possibilities. They are seen as raw materials for the production of different metabolites, biopolymers, organic acids, antibiotic, amino acids, enzyme, bakery yeast, and also the butanol and hydrogen (Shahravy et al, 2012;Qureshi et al, 2012;Abd-Alla et al, 2012;Aditiya et al, 2016). The present work consists of the realization of an experimental solar batch fermenter prototype operating with the solar water heater, in order to reduce the energy consumed and to ensure anaerobic fermentation medium for the CDPW dates juice at 30%, and for producing a high quality and quantity of bioethanol at low cost after distillation.…”

Every year, more than 236,807 tons, equivalent to 30% of date-palm fruits produced in Algeria, is lost during picking, storage, and commercialization processes. Gasification of this huge biomass can generate biogas such as bioethanol, biodiesel, gasoline and other useful substances. Bioethanol is becoming the main biofuel produced by chemical synthesis or anaerobic fermentation from biomass and is significant for industrial development, investment, and use. It is eco-friendly, moderately costly and cleaner than other gasses. Actually, due to modern biotechnologies, it is possible to valorise the common date-palm waste (CDPW) by bioconversion and to commercialize them in local and international markets in the form of new products with an acceptable added value such as bioethanol. CDPW is a renewable and sustainable resource of energy that is not greatly used in industries. The date is rich in biodegradable sugars, providing bioethanol after fermentation during 72 h at 30°C in the presence of Saccharomyces cerevisiae yeast and the distillation of date's juice obtained. In the first experience, a solar batch fermenter (SBF) of 50L capacity, and a butane gas distiller using a cocotte (cooker) of 30L capacity was designed and constructed. The bioconversion systems led to the production of 250 mL/kg of ethanol at 90° after distillation of the CDPW juice at 78°. This is in comparison to the theoretical ethanol directly produced from sugar by chemical synthesis process. The 33% efficiency that was obtained appeared satisfactory and it encouraged the great scaling development of bioethanol based on CDPW biomass and other raw materials abundant in Algeria Sahara.

“…The total sugar content give the ranking; H'loua, Timjouhart H'mira and Tafezouine. The reducing sugars content for all varieties date powders obtained is not agreement with results (50g.L ) obtained by Shahravy et al [33] and results (60 ± 0,4%) for date powders observed by Benahmed et al [13]. The report Sugars/Water gives an idea of the osmotic pressure, the absorption capacity of power, energetic and nutritional value and the water activity (Aw) which influences the bacteria charge.…”

This study was carried out to determine the possibility of replacement of sucrose by date powders obtained from common Algerian varieties known as low values during the manufacture of the soft drinks. In order to obtain the date powders, four varieties of dates H'amira, H'loua, Tefezouine and Timjouhart were dried at 90°C during 2h. Date powders variety H'lowa was selected according to these good qualities for substitution sucrose (yield, optical density, moisture, ash, total and reducing sugars, report Sugars/Water, proteins, the rehydration power and sensitivity in temperature). The date powder variety H'lowa had significantly higher color, taste and texture score followed by Tefezouine, then Timjouhart and H'mira. The total or partial replacement of sucrose by date powders variety H'lowa improves the nutritional quality of the products (acidity, reducing sugars and ash). The microbiological quality of most of the soft drinks prepared with date powders were not satisfactory as total plat count and, yeasts and moulds. Complete replacement of sucrose improves the sensory quality of soft drinks included color, taste, acidity and odor.
