Extracts from 44 species of seaweed from Gran Canaria (Canary Islands, Spain) were screened for the production of antibacterial and antifungal compounds against a panel of Gram-negative and Gram-positive bacteria, mycobacteria, yeasts and fungi. A total of 28 species displayed antibacterial activity, of which six also showed antifungal activity. Asparagopsis taxiformis and Cymopolia barbata were ...... hiện toàn bộ
Microbial mats and the search for minimal ecosystemsInternational Microbiology - Tập 5 - Trang 177-188 - 2002
R. Guerrero, M. Piqueras, M. Berlanga
This article reviews some ecological concepts common to all kinds of ecosystems, describes the characteristics of microbial mats, and focuses on the description of the Ebro Delta microbial mats, to assess whether they fit the concept of a minimal ecosystem. First, microorganisms as components of ecosystems are considered, and some features of microbial life, including ubiquity, size and metabolis...... hiện toàn bộ
The calculative nature of microbial biofilms and bioaggregatesInternational Microbiology - Tập 5 - Trang 107-116 - 2002
Douglas E. Caldwell
Biological proliferation is optimized at various levels of organization, including the molecule (e.g. nucleic acids, prions), the cell (e.g. prokaryotic cells, eukaryotic cells), and the community (e.g. microbial biofilms, bioaggregates). Although it was initially assumed that this occurred through the genesis of information within DNA alone, it now appears that innovative design originates at ot...... hiện toàn bộ
Potential of Burkholderia cepacia RQ1 in the biodegradation of heavy crude oilInternational Microbiology - Tập 4 - Trang 83-87 - 2001
A. Okoh, S. Ajisebutu, G. Babalola, M. Trejo-Hernandez
The potential of Burkholderia cepacia strain RQ1 in the biodegradation of heavy crude oil (Maya) was assessed to develop an active indigenous bacterial consortium for the bioremediation of crude oil-polluted systems in Nigeria. The heavy crude oil (Maya) was utilized as sole source of carbon, attaining maximum cell densities of 108 cfu ml–1 from an initial 105 cfu ml–1 in 15 days. Biomass also in...... hiện toàn bộ
