Screening of endophytic sources of exopolysaccharides: Preliminary characteriza...

Made available in DSpace on 2022-04-29T07:32:45Z (GMT). No. of bitstreams: 0 Previous issue date: 2016-06-01; Endophytic fungi have been described as producers of important bioactive compounds; however, they remain under-exploited as exopolysaccharides (EPS) sources. Therefore, this work reports on EPS production by submerged cultures of eight endophytes isolated from Piper hispidum Sw.; belonging to genera Dia...

BIOPROSPECÇÃO DE PEPTÍDEOS ANTIMICROBIANOS EM LARVAS DE CALLIPHORIDAE (DIPTERA)...

Os insetos apresentam a maior biodiversidade entre a classe Animal e são fontes ricas de produtos biotecnológicos. Espécies da família Calliphoridae (Diptera) apresentam hábitos necrófagos durante a fase larval, assim são expostas a diferentes microrganismos, produzindo peptídeos antimicrobianos (AMPs) como sistema de defesa. O objetivo deste trabalho foi realizar um levantamento bibliográfico dos principais pe...

Plant growth-promoting activity of wild-type and bromate-resistant mutant of th...

Endophytes may play important roles in agriculture. Spontaneous or induced mutant strains may increase their biotechnological properties. Seventeen Colletotrichum endophytic fungi were investigated for their plant growth-promoting characteristics (in vitro phosphate solubilization, IAA, and siderophore production). The five best strains were inoculated into bean seeds, and the most prominent isolate was selecte...

Toxicity of β-(1→3,1→6)-ᴅ-glucans produced by Diaporthe sp. endophytes on Metar...

Previously, our study reported that β-(1→3,1→6)-ᴅ-glucans produced by endophytes Diaporthe sp. G27-60 and G65-65 (GenBank accession codes JF766998 and JF767007, respectively) are promising antiproliferative agents against human breast carcinoma (MCF-7) and hepatocellular carcinoma (HepG2-C3A) cells. However, effects of Diaporthe exopolysaccharides on eukaryotic healthy cells are not described in current literat...

Bioprospection and molecular phylogeny of culturable endophytic fungi associate...

Endophytic microorganisms live inside the plants without causing any damage to their hosts. In the agricultural field, these endophytes might be a strategy of biological control for phytopathogens. We aimed to isolate endophytic fungi from yellow passion fruit (Passiflora edulis) leaves, evaluating its biocontrol capacity by in vitro antagonism against phytopathogen Colletotrichum sp. CNPU378. We also carried o...

Endoglucanase production by endophytic fungi isolated from Vitis labrusca L. wi...

Endoglucanases are enzymes widely employed in different industrial fields, albeit with high production costs. Studies on new microbial sources and low-cost substrates are highly relevant, including those on agro-industrial. Current analysis evaluates peanut hull (PH) and sawdust (SD) as substrates for submerged cultures of 14 endophytic fungi isolated from grapevine (Vitis labrusca L.) cultivars Bordô and Conco...

Action of Bacillus thuringiensis (Bacillales: Bacillaceae) in the midgut of the...

Made available in DSpace on 2019-10-06T16:47:23Z (GMT). No. of bitstreams: 0 Previous issue date: 2019-11-30; Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES); The relevance of Bacillus thuringiensis in pest control strategies have been increasing in recent decades. This entomopathogenic microorganism is considered safe, and its action is highly selective to target organisms. Its toxic effect...
