Sustainability, Journal Year: 2024, Volume and Issue: 16(3), P. 1116 - 1116

Published: Jan. 28, 2024

Two-phase olive pomace is a byproduct of the olive-oil extraction process that sometimes processed further to recover more oil. During oil production, especially in early stages processing, odours can be produced. These are serious nuisance, and around processing facilities, as well for nearby communities. strong unpleasant, they may result various issues, including environmental concerns. Thus, this paper, effect storage drying on composition two-phase was investigated. Several physicochemical instrumental analyses were performed, it concluded structural elements not ones affected during drying. Storage mainly impact content pomace, leading an acidity increase production odorous oxidation compounds. Volatile acids, methyl, ethyl esters released into atmosphere, thus causing nuisance.

The production of olive oil results in various by-products such as leaves and pulp, which can be utilized animal nutrition. aim the present study was to investigate effects dietary pulp on oxidative status fatty acid (FA) composition broiler breast meat. A total 120 one-day-old male Ross 308 broilers were randomly divided into 5 experimental groups: 1 control group (Cont) without supplementation 4 groups supplemented with either 5% or 10% (OLeav5; OLeav10) (OPulp5; OPulp10). Blood muscle samples taken at end experiment. showed that addition did not significantly alter concentration malondialdehyde (MDA) antioxidant capacity lipid-soluble compounds (ACL) blood enzyme activities liver. However, water-soluble (ACW) serum reduced receiving (p = 0.002). In addition, meat quality parameters affected by intake, although lightness (L*) 0.023) α-tocopherol 0.001) compared control.

High temperatures have detrimental effects on the performance and physiology of broiler chickens. Medicinal plants various biological activities may enhance heat resistance chickens during waves. Therefore, this study aimed to explore potential roles using specific local medicinal alleviate negative impacts stress (HS) in broilers. In study, 180 day-old chicks were used investigate HS dietary indigenous growth performance, antioxidant biomarkers, intestinal health. The assigned six groups (18 pens with 10 per pen) three replicates each. first group, kept under thermoneutral conditions (CON) fed a basal diet. other five exposed recurrent diet (T1, group) or supplemented Artemisia Sieberi (1.25 g/kg feed; T2), Achillea Fragrantissima (15 T3), Olea europaea (10 T4), all previous additives (all-in-one) combined at same dose levels mentioned above (T5). At 21 days age, from each group two phases stress: phase 1 34 (34 ± 1°C) followed by 2 35 39 (37 1°C). results indicate that significantly increased rectal temperature respiration rate Feed intake body weight gain improved groups, while feed conversion ratio was decreased response inclusion plants. Additionally, glutathione peroxidase immunoglobulin G T3, T4, T5 compared groups. induced significant upregulated mRNA shock protein 70 interleukin-8, occludin decreased. showed expression hepatic HSP70 ileum IL-8 genes relative CON T1 conclusion, supplementation these enhances maintains health sustaining productivity conditions.

PLANT-GROWTH-PROMOTING AND ANTIFUNGAL ASSET OF INDIGENOUS DROUGHT-TOLERANT RHIZOBACTERIA ISOLATED FROM OLIVE (Olea europaea L.) RHIZOSPHERE

Journal of Microbiology Biotechnology and Food Sciences, Journal Year: 2024, Volume and Issue: unknown, P. e10588 - e10588

Published: July 2, 2024

Faced with global environmental challenges, the quest for sustainable food production has gathered momentum. While abiotic stresses adversely affect plant health and productivity, Verticillium wilt causes considerable yield losses worldwide, particularly in crops such as olive. Recently, drought-tolerant bacteria have been used to alleviate both stress pathogen pressure crops. In this context, our work focuses on isolation of tolerant indigenous rhizobacteria mitigate these challenges by investigating their role biocontrol tolerance. Thus, a total 94 rhizobacterial strains were isolated from rhizospheres olive trees southeastern Morocco characterized identify growth-promoting that inhibit dahliae. 24 demonstrated vitro suppression dahliae Klebahn, exhibited tolerance different (drought, salinity, high temperature). addition, they proved xerotolerant (Aw ≤ 0.91), halotolerant (≥10% NaCl), thermotolerant (≥ 55°C) capabilities. Beyond, isolates showcased multifaceted traits, phosphate solubilization significant synthesis essential bioactive compounds like siderophores, indole-3-acetic acid hydrolytic enzymes. Evaluating outcomes, three standout emerged due exceptional tolerance, unique qualities, potent antagonistic potential. Molecular analysis identified them Bacillus paranthracis (OZ-60) licheniformis (OZ-48 OZ-77) through 16S rRNA sequencing. Besides enhancing resistance, hold promise bolstering sustainability cultivation fortifying defenses against pathogens.
