“…Numerous studies have shown the antimicrobial properties of plant extracts that can improve the flora and intestinal health of the bird's digestive tract by reducing the number of pathogenic bacteria (Ebrahimi et al 2016;Yadav et al 2016;Jin et al 2020). Disadvantages include the presence of harmful microbes in the gastrointestinal tract, increased protein and amino acid degradation due to the secretion of substances such as urease enzymes by microbes (Sharma et al 2019;Thapa et al 2019). On the base of Hajipour et al (2015) study, using thyme powder and essential oils in broilers diets significantly increased the lactobacilli population and reduced the numbers of E coli, also there have beneficial effect on intestinal cells morphology, So the highest villi and the lowest depth of crypt cells blogged to thyme treatments.…”

This study was conducted to investigate the effects of normal and nanocapsulated forms of thyme and peppermint essential oils on intestinal morphology and microbial population of broilers fed on normal and low crude protein diets. The study was carried out with a total of 320 Ross-308 broiler chickens as a 2×2×2 (2 medicinal plant essential oils, 2 forms of oils and 2 levels of diet crude protein) factorial arrangements with 32 groups (10 chicks per replicate) according to a completely random design. This experiment was done in three periods included: Starter (1-10 days), grower (11-24 days) and finisher (25-42 days). The experimental diets had significant effects on intestinal morphology (P<0.05), so that the use of the usual form of essential oils while reducing the depth of the crypt, increased the ratio of the length of the villa to the depth of the crypt. In use of peppermint essential oil with standard protein, crypt depth increased, and the ratio of villi height to crypt depth was minimal (P<0.05). A decrease in dietary crude protein level reduced the population of lactobacilli in the intestine (P<0.05). However, the level of crude protein in the diet and the form of use of the essential oil, as well as the type of essential oil and its form, did not have significant effects on the intestinal microbial population (P>0.05). Based on the results of this experiment, it can be stated that in broilers, the use of the encapsulated form of thyme essential oil in diets with standard crude protein levels, improved the intestinal morphology and intestinal non-pathogenic microbial population of broilers. Ten percent reduction in dietary crude protein level had adverse effects on measured traits and is not recommended, and in case of reduction of dietary protein, it is necessary to use peppermint essential oils supplements.

“…As a control experiment, UW was only aerated aeration rate to understand the effect of the C. vulgaris on the UW. In addition of the different parameters shown in Table 1 about the quality of the final tre are after algal biomass separation by centrifugation during only 5 min, w enough to harvest the total algal biomass since this microalga is a round nonm ductive cell with size from 2 to 10 µm [44]. In fact, the clear treated water obtain microalgal cells under the optic microscope.…”

Currently, most wastewater treatment plants do not meet the legal requirements, especially regarding phosphorus and nitrogen contents. In this work, real primary urban wastewater (P-UW) was used as culture medium for the growth of Chlorella vulgaris. Experiments were carried out in batch photobioreactors at laboratory scale. To determine the maximum nutrient removal levels and the optimal pH value for C. vulgaris growth, the following pH values were studied: 5, 6, 7, 8, 9, 10, and 11. Additionally, two control experiments were conducted using UW and tap water at the same conditions but without microalgae inoculation. The operational conditions were agitation rate = 200 rpm, T = 25 °C, aeration rate = 0.5 L/min, and continuous light with illumination intensity = 359 µE m−2 s−1. Significant higher growth was obtained at pH = 7. The direct use of C. vulgaris for P-UW treatment demonstrated high removal percentages of organic (COD and BOD5 removal = 63.4% and 92.3%, respectively) and inorganic compounds (inorganic carbon removal = 99.6%). The final biomass was characterized by an accumulation of high energetic compounds, mainly carbohydrates, which ranged between 63.3% (pH = 5) and 82.8% (pH = 11) and represent a source of biofuels. These new achievements open up the possibility of new horizons in urban wastewater treatment.
