nowadays, the use of natural antioxidants as alternative antioxidants is more acceptable than synthetic antioxidants mainly for negative effects such as carcinogenicity and toxicity. this has led to an increasing interest in the search for natural antioxidants. the objectives of this study were to measure total crude phenolic compounds and in sorghum grain as natural antioxidant sources, to det...

Twenty-four (24) adult albino Wistar rats (twelve males and twelve females) were used for the study. The animals were divided into six groups of four rats in each. Proximate analysis was carried out on the plant sample with the following results: crude protein 22.45 ± 0.01%; crude fat (3.45 ± 0.0%); crude fiber (16.0 ± 0.0%) and Ash (9.95 ± 0.2%). Quantitative phytochemical analysis revealed th...

The aim of this study was to evaluate peptidase production by Aspergillus terreus in solid-state bioprocess and evaluate its parameters. The best conditions were 5.0 g of wheat bran as substrate, incubation temperature 30°C, inoculum 2.0x10 spores/g and 75% saline volume, with production reaching 677 U/mL (5400 U/g culture medium) after 72 h of fermentation. Biochemical characterization of the ...

Laccases are copper-containing enzymes involved in the degradation of lignocellulosic materials and used in the treatment of phenol-containing wastewater. In this study we investigated the effect of culture conditions, i.e. submerged or semi-solid, and copper supplementation on laccase production by Trametespubescens grown on coffee husk, soybean pod husk, or cedar sawdust. The highest specific...

Objective: To investigate the antifungal activity of crude extract of leaves of Tamarix dioica tree. Material and Methods: Antifungal activity of crude extract of T. dioica leaves was studied. The extract was dissolved in Dimethyl Sulfoxide, then six strains of fungi were subjected to crude extract separately by agar tube dilution method. Inhibitory effect of extract in millimeters was determin...

objective:  anchomanes difformis is a member of the plant family araceae which is used as a diuretic but also has other medicinal applications. this study investigates the dietary effects of a. difformis on the kidneys of adult wistar rats. materials and methods: sixteen rats were used and were weighed, before and after the experiment. all rats were randomly divided into four groups. all groups...

Holocellulose structures from agro-industrial residues rely on main and side chain attacking enzymes with different specificities for complete hydrolysis. Combinations of crude enzymatic extracts from different fungal species, including Aspergillus terreus, Aspergillus oryzae, Aspergillus niger and Trichoderma longibrachiatum, were applied to sugar cane bagasse, banana stem and dirty cotton res...

The objective of this study was to examine the action of the crude extract of Duddingtonia flagrans (isolates AC001 and CG722) on infective larvae (L3) of cyathostomins in coprocultures and to confirm its proteolytic activity by means of a zymogram. The following groups were formed in coprocultures: Group 1: 10 mL of crude extract of D. flagrans (AC001); group 2: 10 mL of crude extract of AC001...

13 The nutritive value of 20 forage plants commonly used for feeding pigs in the Democratic 14 Republic of the Congo was studied to determine chemical composition, protein amino acid 15 profiles, mineral content, and in vitro digestibility using a two-steps method combining an 16 enzymatic pepsin and pancreatin hydrolysis followed by a 72h gas-test fermentation. The 17 highest protein contents ...

Banana is one of the most important crops, providing multiple benefits. Although it has been widely studied for its health benefits, little information can be found about proteins. This study determined antihypertensive and antioxidant activities crude, purified, hydrolyzed protein extracts from ‘Señorita’ banana pulp. Crude proteins were extracted using Tris-HCl buffer purified through ammoniu...
