Current Understanding on Adhesion and Biofilm Development in < em > Actinobacteria < /em >
Int J Microbiol. 2021 May 22;2021:6637438. doi: 10.1155/2021/6637438. eCollection 2021.ABSTRACTBiofilm formation and microbial adhesion are two related and complex phenomena. These phenomena are known to play an important role in microbial life and various functions with positive and negative aspects. Actinobacteria have wide distribution in aquatic and terrestrial ecosystems. This phylum is very large and diverse and contains two important genera Streptomyces and Mycobacteria. The genus Streptomyces is the most biotechnologically important, while the genus Mycobacteria contains the pathogenic species of Mycobacteriaceae. ...

Coexistence of Virulence Factors and Efflux Pump Genes in Clinical Isolates of < em > Pseudomonas aeruginosa < /em > : Analysis of Biofilm-Forming Strains from Iran
Conclusions. In this study, we suggested that the presence of a multidrug resistance efflux pump, MexEF-OprN, significantly reduced P. aeruginosa pathogenicity. In contrast, the presence of the MexAB-OprM and MexCD-OprJ pumps did not affect virulence.PMID:34093708 | PMC:PMC8163533 | DOI:10.1155/2021/5557361 (Source: International Journal of Microbiology)

Screening and Characterization of Thermostable Amylase-Producing Bacteria Isolated from Soil Samples of Afdera, Afar Region, and Molecular Detection of Amylase-Coding Gene
This study aimed at screening and characterizing amylase-producing bacteria isolated from soil samples of Afdera, Afar Region, and detection of their amylase-coding genes. Thus, a total of 49 bacterial isolates were obtained from the collected soil samples. Out of these, three isolates (M2, M8, and M13) were selected on the basis of diameter of the average clear zone formation and time taken to decolorize iodine solution. Based on their morphological and biochemical characteristics, the isolates were identified as genus Bacillus. PCR amplification and detection of the amylase-coding gene confirmed the presence of the amyla...

Trend of Bacterial Uropathogens and Their Susceptibility Pattern: Study of Single Academic High-Volume Center in Italy (2015-2019)
Int J Microbiol. 2021 Apr 21;2021:5541706. doi: 10.1155/2021/5541706. eCollection 2021.ABSTRACTUrinary tract infections (UTIs) are a very widespread infection that can occur in disparate age range, in both sexes and in pregnancy/menopause state. Treatment of UTIs is difficult due to the emergence of antibiotic-resistant bacterial strains. The present study shows five years of data collected on patients admitted at the University Hospital "San Giovann di Dio e Ruggi d'Aragona" in Salerno, Italy. The investigation exhibits the incidence of the infection, of the gender, and of the age group affected, identifying the...

Production, Optimization, and Characterization of an Acid Protease from a Filamentous Fungus by Solid-State Fermentation
Int J Microbiol. 2021 Apr 29;2021:6685963. doi: 10.1155/2021/6685963. eCollection 2021.ABSTRACTAcid proteases represent an important group of enzymes, extensively used in food and beverage industries. There is an increased demand for acid proteases adapting to the industrial extreme environment, especially lower pH. Thus, this necessitates the search for a better acid protease from fungi that best performs in industrial conditions. The fungal isolates were isolated from grape and dairy farm soil using potato dextrose agar and further screened for protease production based on the hydrolysis of clear zone on skim milk agar. ...

Production of Biosurfactants by Ascomycetes

Currently, most synthetic surfactants are derived from petroleum. However, these surfactants are usually highly toxic and are poorly degraded by microorganisms. To overcome these problems associated with synthetic surfactants, the production of microbial surfactants (called biosurfactants) has been studied in recent years. Most studies investigating the production of biosurfactants have been associated mainly with bacteria and yeasts; however, t...
