Characterization of Lactic Acid Bacteria Isolated From Rotting Oranges and Use of Agropastoral Processing By-products as Carbon and Nitrogen Sources Alternative for Lactic Acid Production.

This study investigated the ability of lactic acid bacteria (LAB) isolated from oranges to use fish by-products (FB) and chicken by-products (CB) as nitrogen sources alternative to yeast extract for lactic acid (LA) production in a papaya by-product medium as a carbon source. Once the fermentation agents had been isolated, they were subjected to biochemical and molecular characterization. Inexpensive nitrogen sources, precisely CB and FB, were prepared, freeze-dried, and yield evaluated.

Multidrug Resistant Enteric Bacteria from Cancer Patients Admitted in Douala Laquintinie Hospital, Littoral Region of Cameroon.

Patients with cancer have weakened immune systems, making them more vulnerable to infections. This study was carried out to determine the bacterial origins of enteric disorders in cancer patients and noncancer patients at the Oncology Department of Laquintinie Hospital in Douala. A cross-sectional study was conducted from October 2021 to March 2023.

Psoralen Isolated from the Roots of Welw. Modulate Th1/Th2 Cytokines and Inflammatory Enzymes in LPS-Stimulated RAW 264.7 Macrophages.

is a widely used plant spice in traditional African medicine to treat pain-related conditions. However, the anti-inflammatory mechanisms underlying this activity and the main active ingredients of have not yet been fully characterized. This study aimed to isolate and identify the main active anti-inflammatory constituents of the extract and to investigate the underlying anti-inflammatory mechanisms in murine macrophages.

Effect of boiling and oven roasting on some physicochemical properties of sunflower seeds produced in Far North, Cameroon.

The effects of different processing methods on proximate composition, total phenolic content, antioxidant activity, lipid oxidation, and mineral contents of sunflower seeds produced in Far North Region of Cameroon were evaluated. Mean moisture, ash, lipid, protein, fiber, and carbohydrate contents of raw sunflower seeds were 6.60%, 2.

Effect of Traditional Drying Methods on Proximate Composition, Fatty Acid Profile, and Oil Oxidation of Fish Species Consumed in the Far-North of Cameroon.

The purpose of this study is to evaluate the effects of two traditional drying methods on proximate composition, lipid oxidation, and fatty acid composition of two freshwater fish species from Maga Lake in Cameroon. As shown by the results, these two methods significantly ( < 0.05) decrease moisture content in the two fish species while ash and lipid content significantly increases ( < 0.

Characterization of corn, cassava, and commercial flours: Use of amylase-rich flours of germinated corn and sweet potato in the reduction of the consistency of the gruels made from these flours-Influence on the nutritional and energy value.

Malnutrition appears in weaning age and is usually due to weaning food which is of low nutritional value. This problem led us to investigate the study of the physicochemical and functional properties of cassava flours and corn flours, and the fluidification of the gruels made from these flours by germinated yellow corn and sweet white potato flours. To do this, the approximate chemical composition, physical and functional properties, and ability of amylase-rich flours to digest the starch in order to reduce consistency were evaluated.

Optimization of the extraction of natural antioxidants from leaves and evaluation of their ability to preserve palm olein from oxidation during accelerated storage.

Response surface methodology (RSM) was used to optimize the extraction of phenolic antioxidants of leaves and to evaluate the effect of optimized extract and storage time on the stability of palm olein. The optimization of the extraction process was conducted, and the total polyphenol value of 127.06 mg GAE/g and scavenging activity of 90.

Effect of smoking and refrigeration on lipid oxidation of : A fish commonly consumed in Cameroon.

Changes in lipids of herring () muscle during different smoking methods and 9 days of refrigeration at 4°C were investigated. The proximate analysis of raw herring revealed that the total lipid, the total protein content and the crude ash were 10.20%, 69.

Effect of Boiling and roasting on lipid quality, proximate composition, and mineral content of walnut seeds produced and commercialized in Kumba, South-West Region Cameroon.

The effect of boiling and roasting on the lipid quality, proximate composition, and mineral content of African walnut seeds () was assessed. Results indicated that the quality of walnut oil significantly ( < .05) reduces with the treatments.

Valorization of soursop flowers ( L.) as potent source of natural antioxidants for stabilization of palm olein during accelerated storage.

This study investigates the effect of soursop flowers methanolic extract on the physicochemical characteristics of palm olein during accelerated storage. After analysis of the extract by determining its total phenolic content by colorimetry and identification of some of its phenolic antioxidants by HPLC-DAD(Diode Array Detector), preliminary antioxidants tests have been done. After that, the extract was added in palm olein at concentrations 200-1800 ppm.
