Microbial Products and Biofertilizers in Improving Growth and Productivity of Apple – a Review

Walid Fediala Abd El-Gleel Mosa/ Lidia Sas-Paszt/ Mateusz Frąc/ Paweł Trzciński

The excessive use of mineral fertilizers causes many negative consequences for the environment as well as potentially dangerous effects of chemical residues in plant tissues on the health of human and animal consumers. Bio-fertilizers are formulations of beneficial micro­organisms, which upon application can increase the availability of nutrients by their biological activity and help to improve soil health. Microbes involved in the formulation of bio-fertilizers not only mobilize N and P but med(..)

The Role of Staphylococcus aureus in Secondary Infections in Patients with Atopic Dermatitis (AD)

Aneta Buda/ Jacek Międzobrodzki

Staphylococcus aureus colonizes the mucous membrane of the nasal vestibule of a significant number of healthy people. These microorgan­isms are opportunistic pathogens, that in favorable conditions, may cause infections of various course, location or manifestation. Second­ary infections emerge in cases when other risk factors contribute to such a change. One of the diseases during which S. aureus changes its saprophytic character to a pathogenic one is atopic dermatitis (AD), an allergic skin co(..)

Molecular Characterization of Shiga Toxin-Producing Escherichia coli Strains Isolated in Poland

Aleksandra Januszkiewicz/ Waldemar Rastawicki

Shiga toxin-producing Escherichia coli (STEC) strains also called verotoxin-producing E. coli (VTEC) represent one of the most important groups of food-borne pathogens that can cause several human diseases such as hemorrhagic colitis (HC) and hemolytic – uremic syndrome (HUS) worldwide. The ability of STEC strains to cause disease is associated with the presence of wide range of identified and putativevirulence factors including those encoding Shiga toxin. In this study, we examined the distribu(..)

Distribution and Identification of Endophytic Streptomyces Species from Schima wallichii as Potential Biocontrol Agents against Fungal Plant Pathogens

Ajit Kumar Passari/ Vineet Kumar Mishra/ Vijai Kumar Gupta/ Ratul Saikia/ Bhim Pratap Singh

The prospective of endophytic microorganisms allied with medicinal plants is disproportionally large compared to those in other biomes. The use of antagonistic microorganisms to control devastating fungal pathogens is an attractive and eco-friendly substitute for chemi­cal pesticides. Many species of actinomycetes, especially the genus Streptomyces, are well known as biocontrol agents. We investigated the culturable community composition and biological control ability of endophytic Streptomyces (..)

Pexophagy in Penicillin G Secretion by Penicillium chrysogenum PQ-96

Wiesław Kurzątkowski/ Anita Gębska-Kuczerowska

Penicillin G oversecretion by Penicillium chrysogenum PQ-96 is associated with a strictly adjusted cellular organization of the mature and senescent mycelial cells. Abundant vacuolar phagy and extended cellular vacuolization combined with vacuolar budding resulting in the formation of vacuolar vesicles that fuse with the cell membrane are the most important characteristic features of those cells. We suggest as follows: if the peroxisomes are integrated into vacuoles, the penicillin G formed in p(..)
