The present work aims to study a new chitinase from Bacillus thuringiensis subsp. kurstaki.BUPM255 is chitinase-producing strain of B. thuringiensis, characterized by its high chitinolytic and antifungal activities. cloning sequencing the corresponding gene named chi255 showed an open reading frame 2031 bp, encoding 676 amino acid residue protein. Both nucleotide sequences similarity analyses revealed that gene, presenting several differences published chi genes thuringiensis. identification...
Abstract BACKGROUND Fusarium maize ear and root rot disease caused by verticillioides has become one of the most serious fungal diseases associated with production. Due to their abilities promote plant development manage diseases, bacterial endophytes provide a more promising approach for treating this vascular disease. RESULTS This work was undertaken selection identification isolates as growth promoters biocontrol agents against F. in agroecosystems. A screening procedure consisting vitro...
Two novel Algerian field-collected isolates were selected for their antifungal activity against Zymoseptoria tritici (teleomorph Mycosphaerella graminicola). The strains, termed Alg.24B1 and Alg.24B2, identified as Bacillus subtilis simplex since respective nucleotide sequences of the 16S rRNA gene 100% 99.93% identical to those B. simplex, respectively. activities Alg.24B2 evaluated by well diffusion method compared other species. maximum was obtained after two days confrontation bacterial...
Abstract This study investigates the optimization of culture conditions for enhancing Photorhabdus temperata biopesticide production using wastewater (WS4) as a raw material. Box-Behnken design (BBD) was used to evaluate effects carbon nitrogen ratio (C/N), sodium chloride concentration and inoculum size on P. biomass insecticidal activity. For an enhanced production, optimum operating were follows: = 4%; C/N 12.5 [NaCl] 4 g/L two responses. 1.95 2.75 fold improvements in oral toxicity...
Bacillus thuringiensis is the leading microbial-based biopesticide, thanks to its parasporal crystal proteins or δ-endotoxins, which are toxic insect larvae upon ingestion. Once in midgut, solubilized by alkaline pH and δ-endotoxins activated proteolytic cleavage. Thanks high efficiency as a several efforts have been made enhance growth production, various types of culture media. In this study, medium based on wheat bran (WB), by-product cereal grain milling, was used grow produce...
The study investigates whether mandatory extraction payment disclosures (EPD), a policy intervention involving Country-by-Country Reporting (CbCR) in extractive industries, affects corporate tax avoidance. Based on sample of firms listed the London Stock Exchange over period from 2010 to 2021, and using Difference-in-Differences (DiD) model including firm year fixed effects, results showed decline level avoidance British post-EPD requirement implementation, relative U.S. extractive/British...
Research Question: Does public country by reporting (CbCr) deter multinationals' tax avoidance practices operating in extractive industries? Motivation: Public CbCr has already been implemented for two specific sectors, namely the financial and sectors. Prior studies have focused on of EU banks around implementation requirement (Joshi et al., 2020; Eberhartinger Overesch & Wolff, 2021). However, how resource-extracting multinationals respond to regulation are scarce. This study seeks...
