Effect of Dried Mealworms (), Larvae and Olive Leaves ( L.) on Growth Performance, Carcass Yield and Some Blood Parameters of Japanese Quail ().

The aim of this study was to investigate the effect of meal (TM) and/or olive leaf powder (OL) supplementation to quail diet on animal performance, carcass yield and some blood parameters. One hundred and forty-four 1-day-old Japanese quails (body weight: 29.9 ± 0.

Characterization of New Fengycin Cyclic Lipopeptide Variants Produced by Bacillus amyloliquefaciens (ET) Originating from a Salt Lake of Eastern Algeria.

Fengycin antibiotic displays a strong antifungal activity and inhibits the growth of a wide range of plant pathogens especially filamentous fungi. The main objective of the present study is to characterize fengycin variants produced by B. amyloliquefaciens strain (ET).

Effects of or olive leaf () powder supplementation on growth performance, carcass yield, and blood biochemical parameters in broilers.

Aim: This study was aimed to evaluate the effects of (white wormwood) or olive leaf () powder supplementation on growth performance, carcass yield, and serum biochemical parameters in broilers.

Materials And Methods: The study was conducted from April to May 2017 in Chemini region, Northern Algeria. A total of 60 1-day-old Ross 308 male chicks were divided into three groups consisted of 10 chicks, in each of two replications.

Optimization of Baker's Yeast Production on Date Extract Using Response Surface Methodology (RSM).

This work aims to study the production of the biomass of on an optimized medium using date extract as the only carbon source in order to obtain a good yield of the biomass. The biomass production was carried out according to the central composite experimental design (CCD) as a response surface methodology using Minitab 16 software. Indeed, under optimal biomass production conditions, temperature (32.

Biocontrol and Plant Growth Promotion Characterization of Bacillus Species Isolated from Calendula officinalis Rhizosphere.

The phenotypic and genotypic diversity of the plant growth promoting Bacillus genus have been widely investigated in the rhizosphere of various agricultural crops. However, to our knowledge this is the first report on the Bacillus species isolated from the rhizosphere of Calendula officinalis. 15 % of the isolated bacteria were screened for their important antifungal activity against Fusarium oxysporum, Botrytis cinerea, Aspergillus niger, Cladosporium cucumerinium and Alternaria alternata.

In vitro and in vivo characterization of plant growth promoting Bacillus strains isolated from extreme environments of Eastern Algeria.

This report is to our knowledge the first to study plant growth promotion and biocontrol characteristics of Bacillus isolates from extreme environments of Eastern Algeria. Seven isolates of 14 (50 %) were screened for their ability to inhibit growth of some phytopathogenic fungi on PDA and some roots exudates. The bacteria identification based on 16S r-RNA and gyrase-A gene sequence analysis showed that 71 % of the screened isolates belonged to Bacillus amyloliquefaciens and the rest were closely related to B.
