2015 Aim: Bioreactors are an essential component in every biotechnological process. Due to the multitude of different microbial and mammalian organisms used for production of complex products, novel concepts for customized cultivations are necessary. Results: A ceramic capillary-based bioreactor enabling a novel approach for steadystate biofilm cultivation is presented. A model for the determin...

Microbial transformations have been unnoticeably exploited by mankind for centuries especially in the context of early food industries. The modern biotechnology uses microbial cells in a more directed approach to produce enzymes, antibiotics, amino acids and other metabolites of economical interest. Food and mining industries are also sustained by natural microbial activities tailored in a way ...

Actinomyces israelii is an uncommon cause of upper genital tract infection. This gram-positive anaerobe is occasionally noted on the Papanicolau smear of asymptomatic patients utilizing the intrauterine device. In this case, a 57-year-old woman presented with postmenopausal vaginal bleeding. A Pap smear showed filamentous microorganisms consistent with Actinomyces israelii (A). Despite a negati...

The antimicrobial activity and the MIC values of the diethyl ether, acetone, chloroform, petroleum ether, and ethanol extracts of the lichen Hypogymnia tubulosa and its 3-hydroxyphysodic acid constituent have been investigated against some microorganisms. At least one of the extracts or 3-hydroxyphysodic acid showed antimicrobial activity against Aeromonas hydrophila, Bacillus cereus, Bacillus ...

The acetone extract of the lichen Ramalina farinacea and its (+)-usnic acid constituent showed antimicrobial activity against Bacillus subtilis, Listeria monocytogenes, Proteus vulgaris, Staphylococcus aureus, Streptococcus faecalis, Yersinia enterocolitica, Candida albicans, and Candida glabrata. Norstictic acid was active against Aeromonas hydrophila as well as the above microorganisms except...

INTRODUCTION Diseases of the maxillary sinus have been associated with dental roots near the maxillary sinus that have undergone endodontic treatment. OBJECTIVE To investigate the presence of filamentous fungi in patients with dental roots near the maxillary sinus who had apical periodontitis treated endodontically, and to alert practitioners that this could be a possible avenue of contaminat...

Filamentous fungi and oomycetes are eukaryotic microorganisms that grow by producing networks of thread-like hyphae, which secrete enzymes to break down complex nutrients, such as wood and plant material, and recover the resulting simple sugars and amino acids by osmotrophy. These organisms are extremely similar in both appearance and lifestyle and include some of the most economically importan...

Fungi is an extensive group of eukaryotic microorganisms, generally they are microscopic and usually filamentous. It is estimated that there are between 70,000 and 1.5 millions species of fungi, most of them are being discovering and describing (Agrios, 2005). Most of the known hundred thousand fungal species are strictly saprophytic, living on decomposing dead organic matter. About fifty speci...

A new more sustainable agricultural system needs to be developed increase production without compromising human and animal health preserving essential resources, such as soil, water diversity. Bio-inoculants can a tool favor this transition, they replace or complement agrochemicals that do not meet the above premises. generated from endophytic filamentous fungi mycorrhizal fungi, whether used i...

Endophytic fungi produce a plethora of secondary metabolites, which may open new avenues to study their applicability in pharmaceuticals. Therefore, the present focuses on fungal endophytic community Artemisia asiatica. During our work, endophytes were isolated from medicinal plant, A. The culturable identified using molecular techniques and biodiversity, richness tissue specificity examined. A...
