Article Synopsis
  • This study explores the use of cyclopentyl methyl ether (CPME) as a more efficient and environmentally friendly alternative to hexane for extracting fenugreek seed oil.
  • In simulations and experiments, CPME outperformed hexane, yielding 7.23% oil compared to hexane's 4.25% and preserving more beneficial fatty acids and bioactive compounds.
  • CPME also demonstrates better oxidative stability and lower volatile organic compound emissions, making it a sustainable option for oil extraction while offering improved antioxidant and antibacterial properties.

Background: Managing postoperative setting, regarding pain and anxiety after cesarean delivery is crucial for the mother's recovery, her emotional well-being, mother-infant bonding and initiating breastfeeding. Although some research have suggested that aromatherapy with lavender essential oil can be effective in reducing pain and anxiety in various medical settings, the efficacy of lavender aromatherapy in the postoperative setting after cesarean delivery is less well-studied. We aimed to assess the effectiveness of lavender essential oil therapy in the management of pain and anxiety after cesarean delivery.

Phenolic constitutents, antioxidant and repellent activities of coriander ( L.) fruits using different solvent extracts.

Int J Environ Health Res

January 2024

Laboratory of Applied Biotechnology in Agriculture, National Institute of Agronomic Research of Tunisia (INRAT), University of Carthage, Ariana, Tunisia.

The organic solvent extracts (hexane, chloroform, acetone, methanol and water) of coriander fruits were reported for their antioxidant and repellent activities. The methanol and acetone extracts revealed the highest antiradical activity as compared to the other solvent extracts. HPLC analysis revealed that phenolic acids were the major compounds in chloroform and acetone extracts, whereas flavonoids in methanol and water extracts.

Research Unit of Analysis and Process Applied on the Environmental-APAE UR17ES32-Higher Institute of Applied Sciences and Technology Mahdia, University of Monastir, Tunisia.

Effluents discharged by poultry meat industries are heavily polluted with raw materials, such as fat, blood residues, and proteins. Thus, untreated effluents directly discharged into the environment may constitute a public health threat. This study aims to evaluate the bacterial diversity of three water qualities: industrial poultry wastewater (PWW), tap water (TW), and PWW diluted with TW (50 : 50) (V/V) (TWPWW) by the combination of culture-independent and culture-dependent approaches.

Algae and Their Metabolites as Potential Bio-Pesticides.

Microorganisms

January 2022

Laboratory of Systems Microbiology and Applied Genomics, Department of Environmental Engineering, University of Patras, 2 Seferi St., 30131 Agrinio, Greece.

An increasing human population necessitates more food production, yet current techniques in agriculture, such as chemical pesticide use, have negative impacts on the ecosystems and strong public opposition. Alternatives to synthetic pesticides should be safe for humans, the environment, and be sustainable. Extremely diverse ecological niches and millions of years of competition have shaped the genomes of algae to produce a myriad of substances that may serve humans in various biotechnological areas.

Concerning human and environmental health, safe alternatives to synthetic pesticides are urgently needed. Many of the currently used synthetic pesticides are not authorized for application in organic agriculture. In addition, the developed resistances of various pests against classical pesticides necessitate the urgent demand for efficient and safe products with novel modes of action.

Article Synopsis
  • Lead (Pb) is a toxic metal that causes various health issues, and halophytic plants like Sarcocornia perennis may help mitigate these effects.
  • In a study with rats, lead exposure resulted in increased kidney weight, oxidative stress, and inflammation, while decreasing liver weight and certain antioxidant levels.
  • When S. perennis extract was administered, it improved antioxidant activity and reduced markers of inflammation and oxidative damage caused by lead, demonstrating its potential protective effects against lead toxicity.

Presence of mycotoxins in sorghum and intake estimation in Tunisia.

Food Addit Contam Part A Chem Anal Control Expo Risk Assess

October 2014

a Laboratory of Molecular Physiology of Plants , Borj-Cedria Biotechnology Center, B.P. 901 , Hammam-Lif 2050 , Tunisia.

Sorghum samples (n = 60) from Tunisian markets were analysed for the occurrence of 22 of both traditional and emerging mycotoxins. Samples were extracted with a QuEChERS-like method and mycotoxins were detected by LC-MS/MS. This method was validated and adequate analytical parameters were obtained.

  • * Out of the samples tested, 50% were contaminated, with AFG2 being the most frequently detected toxin, identified in 11 samples at varying concentrations.
  • * Notably, while some toxins, like HT2 and FB1, were found in several samples, others such as DON, AFG1, AFB2, and T2 were not detected in any of the analyzed grain products.

Aims:   The objective of this work was to study the effect of some factors, linked to grape composition during ripeness process, on the growth and ochratoxin A (OTA) production of Aspergillus carbonarius isolated from grapes.

Methods And Results:   Aspergillus carbonarius isolates were tested (i) in vitro, in Czapek yeast autolysate agar (CYA) at different pHs (2·5-4·5) and incubation times (2-6 days), and (ii) in situ, in fresh grapes collected at different maturation stages. Aspergillus carbonarius was able to grow with the same intensity at the different maturation stages and pH levels tested.

Article Synopsis
  • This study examined how temperature and water levels affect the growth and production of ochratoxin A (OTA) by a fungus called Aspergillus carbonarius using samples from Tunisian vineyards.
  • The researchers found that the best water level for both growth and OTA production was 0.99, while the ideal temperature for growth was 30 degrees Celsius, with a notable decline at 37 degrees Celsius.
  • Maximum toxin production occurred at cooler temperatures (15 to 25 degrees Celsius), and significant OTA levels were produced within just 5 days of incubation, revealing similarities and some differences between Tunisian and other grape isolates.

The effect of three alternating temperatures cycles (20/30, 20/37 and 25/42 degrees C) and photoperiod on growth and Ochratoxin A (OTA) production of six isolates of Aspergillus carbonarius on synthetic nutrient medium were investigated. The different temperature regimes affected significantly both the mycelial growth and the OTA production. The best growth and OTA production were recorded at 20/30 degrees C.
