Biosurfactants are structurally diverse surface-active agents mostly produced by various genera of bacteria, yeast and filamentous fungi that have a wide range applications properties. They surface interfacial activity, temperature pH tolerance, biodegradability, low toxicity anti-adhesive property. Their production was reported to be affected temperature, PH, aeration agitation, salt concentra...

Abstract Cyanobacteria are considered to be among the first microorganisms settle in hot springs where they form a favourable environment for further biological establishment. Nevertheless, exact pioneer species and how early start participating biomineralisation processes remain unknown. The aim of present study was twofold, that is, identify (i.e. Aedipsos area, Greece) record their processes...

Endophytic fungi comprise a group of microorganisms great diversity, which can be modulated by biotic and abiotic factors. The present study aims to understand how environmental factors, blooming cultivars change the diversity endophytic fungal communities in sorghum leaves two forest areas Brazil. Our results showed that Sorghum bicolor has rich diverse community distributed Ascomycota, Basidi...

Mustard bran is enriched with bioactive phenolic compounds and glucosinolates, yet it underutilized as a low-value processing by-product. Here, we investigate the effects of solid-state fermentation (SSF) using various food-grade microorganisms (Aspergillus spp., Rhizopus Bacillus subtilis, Saccharomyces cerevisiae) on phytochemical composition antioxidant activities oriental mustard yellow bra...

Natural pigments derived from microorganisms have many advantages and are widely studied in the food industry. A filamentous fungus, DBFL05, was identified as Aspergillus ustus, which produces a bright abundant brown pigment. This extracellular, water-soluble pigment is highly polar slightly soluble alcohol but insoluble other organic solvents. The stable under sunlight, at pH 2–10, below 100°C...

Nanotechnology is the most promising technology field in 21st century, providing benefits and scientific advances to global development. New nanotechnological devices, platforms, production systems have shown a wide range of applicability, especially for nanoparticle applied microorganism detection/diagnosis, treatment, drug delivery. This review aims point main area through several publication...

OBJECTIVES Assessment of microbial air quality and surface contamination in ambulances and administration offices as a control place without occupational exposure to biological agents; based on quantitative and qualitative analysis of bacteria, yeasts and filamentous fungi found in collected samples. MATERIAL AND METHODS The sampling was done by wet cyclone technology using the Coriolis recon...

The atmosphere plays an important role in the dispersal of microorganisms, as well connectivity most planet's ecosystems. In recent decades, interest microbial diversity and dispersion has increased due to its importance various fields. However, there are few studies on abundance airborne microorganisms factors, such meteorology, that affect their distribution. Likewise, physical-mathematical m...

Temperature is a critical parameter continually monitored by microorganisms. The dynamic environments inhabited by microorganisms evoke constant and effective environmental response strategies that have been elaborated over evolutionary time. For example, a significant rise or fall in ambient temperature initiates a stress response in the organism, commonly known as heat-shock or cold-shock res...

Studies on the action of analogues of folic acid on microbial growth have been limited mainly to species which require an exogenous supply of folic acid or its derivatives for multiplication. They have been designed principally to determine the nature of the relationship between inhibitor and normal metabolite. The pertinent literature may be found in recent reviews (Martin, 1951; Petering, 195...
