About this journal

ISSN: 1178-6361


Aims and scope:

Microbiology Insights is a peer-reviewed, open access journal which encompasses all aspects of the study of microbiology. Studies on all aspects of both prokaryotic and eukaryotic microorganisms and viruses are welcome. Areas such as functionality, infectious disease, food-borne pathogens, drug resistance and antimicrobials, industrial applications and more are also incorporated in this journal. Microorganisms are of increasing importance today, in terms of subjects of study as a way of understanding more complex organisms and processes, as an industrial and medical tool, and also a threat. Open access online journals are more accessible and publish rapidly, allowing greater dissemination of knowledge in this crucial field.

Editorial standards and procedures:

Submissions, excluding editorials, letters to the editor and dedications, will be peer reviewed by two reviewers.  Reviewers are required to provide fair, balanced and constructive reports.  

Under our Fairness in Peer Review Policy authors may appeal against reviewers' recommendations which are ill-founded, unobjective or unfair.  Appeals are considered by the Editor in Chief or Associate Editor.

Papers are not sent to peer reviewers following submission of a revised manuscript. Editorial decisions on re-submitted papers are based on the author's response to the initial peer review report.

Indexing:

This journal is indexed by:

  • CAS 
  • DOAJ
  • Intute
  • OAIster

National Institutes of Health Public Access Policy compliant:

As of April 7 2008, the US NIH Public Access Policy requires that all peer reviewed articles resulting from research carried out with NIH funding be deposited in the Pubmed Central archive.

If you are an NIH employee or grantee Libertas Academica will ensure that you comply with the policy by depositing your paper at Pubmed Central on your behalf.

Abstract

Various herbal teas including German chamomile, Chrysanthemum Vascuflow herb tea, hop, jasmine and orange flowers, sweet marjoram, spearmint and thyme leaves, and papaya-mint tea as well as coffee substitutes (Bambu instant Swiss, Teeccino chocolate-mint, and Teeccino Mediterranean Espresso) were analyzed for fungal contamination and the presence of aerobic mesophilic bacteria (APC). The results of this investigation showed that fungal counts reached levels as high as 5.8 × 105 colony forming units (cfu) per gram. German chamomile harbored the highest fungal contamination. The most common fungi found in herbal teas were Aspergillus niger, Penicillium spp., Eurotium rubrum, E. chevalieri, A. flavus, Fusarium spp., Alternaria alternata, and yeasts. Among the coffee substitutes, only the chocolate-mint coffee was contaminated with low numbers (<1.0 × 103 cfu g−1) of E. rubrum, Ulocladium spp. and Phoma spp., and with yeasts (<100–6.8 × 103 cfu g−1). Aerobic mesophilic bacteria were recovered from 100% of the herbal tea, chocolate-mint and Mediterranean Espresso, and from 50% of the Bambu instant Swiss coffee samples. The highest APC counts of 1.2 × 107 cfu g−1 were observed in spearmint leaves.
