The excessive use of chemicals in plant production, including mineral fertilizers has a harmful effect on the morpho- and physiological state strawberry plants, their yielding, physicochemical properties fruit soil. Increasing effectiveness beneficial microorganisms, i.e. filamentous fungi, arbuscular mycorrhizal fungi (AMF) bacteria, is an essential method reducing amount used to fertilize aim...

While plants can phytoremediate soils that are contaminated with petroleum hydrocarbons, adding microbes to remediate contaminated sites with petroleum-degrading microorganisms and arbuscular mycorrhizal fungi (AMF) is not well understood. The phytoremediation of Arabian medium crude oil (ACO) was done with a Lolium multiflorum system inoculated with an AMF (Glomus intraradices) and a mixture o...

Necrotizing infundibular crystalline folliculitis is a rare condition characterized by folliculocentric waxy papules in the seborrheic areas of adult patients, with intrafollicular filamentous birefringent deposits as histopathologic clue. Although real pathogenesis necrotizing remains unclear, material seems to be derived from an interaction between such superficial microorganisms gram-positiv...

Many methods are now available for achieving selective inhibition of cellular division among a variety of microorganisms. A few reports are available presenting analyses of the composition of bacterial cells grown in the absence of cell division. It was shown by Nickerson and Sherman (1952) with Bacillus cereus that homogenous populations of greatly elongated cells (devoid of interior partition...

Filamentous fungi able to hydrolyse inulin have been isolated from the rhizosphere of plants whose roots contain this polysaccharide. This study reports results concerning the isolation and identification of filamentous fungi from the soil used for sunflower cultivation and from the sunflower rhizosphere cultivated in field and in greenhouse. Fungi were evaluated according to their capacity to ...

Polygalacturonase production under different shear stress environments by Aspergillus sp. was studied. It was found that the rate of enzyme production in the stirred tank fermentor decreased with increasing the stirrer speed in the range 300-750 rpm. On the other hand, in a split cylinder air-lift fermentor, the rate of polygalacturonase production slightly increased with increasing in air ...

Eleven taxa (including eight heretofore undescribed species) of cellularly preserved filamentous microbes, among the oldest fossils known, have been discovered in a bedded chert unit of the Early Archean Apex Basalt of northwestern Western Australia. This prokaryotic assemblage establishes that trichomic cyanobacterium-like microorganisms were extant and morphologically diverse at least as earl...

This study reports the presence of filamentous fungi (ff) in drinking water including biofilms. Ff are not studied sufficiently in drinking water. Ff were highest in winter and had an indirect relation with other microorganisms. Pathogenic fungi were not observed at the mesophilic temperatures used. Penicillium expansum and P. brevicompactum were observed which may affect biofilms by mycotoxin ...
