1. Identification, antibacterial and antifungal effects, antibiotic resistance of some lactic acid bacteria
Abstract A total of 74 lactic acid bacteria (LAB) isolates were obtained from yoghurt, cheese, raw milk, boza and whey. 36 strains were identified at species levels as Lactococcus lactis (15), Lc. garvieae (8) Lactobacillus plantarum (7), Enterococcus faecium (3), Leuconostoc citreum (2) and Lb.casei (1) by MALDI-TOF MS analysis. The strains were tested for

2. Proteomic analysis of the inhibitory effect of chitosan on Penicillium expansum
Abstract The antimicrobial effect of chitosan on Penicillium expansum, a major postharvest pathogen of pome fruit, and the possible mechanisms involved in its effect were examined in this study. Chitosan strongly inhibited spore germination and hyphal growth of P. expansum. Light microscopy and transmission electron microscopy observations revealed that chit

4. Fungal endophytes of Panicum maximum and Pennisetum purpureum: isolation, identification, and determination of antifungal potential
ABSTRACT This study aimed to isolate and identify endophytic fungi from the forage grass P. maximum and evaluate their ability to inhibit the growth of plant pathogenic fungi. One sample from P. purpureum grass was also included. Surface disinfected stem fragments were used for endophytic fungal isolation. One hundred and twenty-six endophytic fungi were iso

5. Effects of the protective, curative, and eradicative applications of chitosan against Penicillium expansum in apples
Abstract Apple is one of the most important temperate fruit to Brazil economy, and the use of synthetic chemicals has been the main method for reducing postharvest diseases, such as the blue mold, caused by Penicillium expansum. This work intends to evaluate the practical utilization of chitosan for blue mold control. For this purpose, fruits were treated in

6. Survey of molds, yeast and Alicyclobacillus spp. from a concentrated apple juice productive process
Bacteria and molds may spoil and/or contaminate apple juice either by direct microbial action or indirectly by the uptake of metabolites as off-flavours and toxins. Some of these microorganisms and/or metabolites may remain in the food even after extensive procedures. This study aim to identify the presence of molds (including heat resistant species) and Ali

7. Polymerase chain reaction (PCR) identification of terverticillate Penicillium species isolated from agricultural soils in eskişehir province
In the present study, nine terverticillate Penicillium isolates (P. griseofulfum, P. puberulum, P. crustosum, P. aurantiogriseum, P. chrysogenum, P. primulinum, P. expansum, P. viridicatum, Eupenicillium egyptiacum) from 56 soil samples were characterized genetically by a PCR method. The DNAs of the strains were isolated using the glass beads and vortexing e

8. Role of killer factors in the inhibitory activity of bio-control yeasts against Penicillium expansum and Aspergillus ochraceus
This work evaluated the antagonism of killer positive yeast strains (isolated from 11 samples of different frozen fruit pulps) against the strains of Penicillium expansum and Aspergillus ochraceus. Of the total 41 killer yeasts tested in YM agar, 19 showed antibiosis against P. expansum and A. ochraceus, with inhibition zone ranging from 10 to 18 mm and 10 t

9. Inibidores naturais no controle in vitro e in vivo de Penicillium expansum
Penicillium expansum é o agente causador da doença em maçã conhecida como mofo azul. O efeito inibitório da capsaicina derivada dos frutos Capsicum spp. e da levedura Hansenula wingei foi avaliado através de ensaios in vitro e in vivo em maçã. A concentração inibitória mínima da capsaicina de 122,16 µg mL-1 foi determinada usando microdiluição

10. Efeito de agentes fumigantes sobre o bolor azul e o mofo cinzento em frutos de maçã
O bolor azul (Penicillium expansum) e o mofo cinzento (Botrytis cinerea) causam perdas significativas em pós-colheita de frutos de maçã. Como alternativa de controle, avaliou-se o efeito da fumigação de ácido acético, acetaldeído, benzaldeído, d-limoneno, timol, metil jasmonato e álcool etílico nas concentrações de 8 e 15 µL/L de ar sobre a ger

11. Changes in hyphal morphology due to chitosan treatment in some fungal species
In this work, changes in the hyphal morphology due to chitosan treatment in some fungal species were studied. Scanning electron microscope (SEM) observations revealed that chitosans with molar fraction of acetyl groups (F A 0.16 and 0.18) and degree of polymerization (DP 1,089 and 1,242) had a direct effect on the morphology of the chitosan-treated fungi, re

12. Growth rate inhibition of phytopathogenic fungi by characterized chitosans
The inhibitory effects of fifteen chitosans with different degrees of polymerization (DP) and different degrees of acetylation (F A) on the growth rates (GR) of four phytopathogenic fungi (Alternaria alternata, Botrytis cinerea, Penicillium expansum, and Rhizopus stolonifer) were examined using a 96-well microtiter plate and a microplate reader. The minimum
