Aerobic and anaerobic bacteria can be identified by growing them in liquid culture:
1. Obligate aerobe
2. Obligate anaerobe
3. Facultative anaerobic organism (continuum with "Facultative aerobic organism")
4. Microaerophile
5. Aerotolerant
An obligate aerobe is an aerobic organism that requires oxygen to grow. Through cellular respiration, these organisms use oxygen to oxidize substances, like sugars or fats, in order to obtain energy. During respiration, they use oxygen as the terminal electron acceptor. They have the advantage of yielding more energy than obligate anaerobes, but face high levels of oxidative stress.[1]
Examples of obligate aerobic bacteria: Nocardia (Gram-positive), and Mycobacterium tuberculosis (acid-fast). Pseudomonas aeruginosa (Gram-negative) is an obligate respirer (incapable of fermentation) but in the absence of oxygen, the bacteria respire using nitrate as a terminal electron acceptor. Some Bacillus species (Gram-positive) are capable of fermentation, although they grow slowly.

- Bacteriological evaluation of tonsillar microbial flora according to age and tonsillar size in recurrent tonsillitis.

The purpose of this study was to isolate the facultative and obligate anaerobes both from the surface and the core of tonsils in recurrent tonsillitis as well as to analyze the variation of isolated bacterial strains according to age and tonsillar size. A prospective study was performed on 111 patients who underwent tonsillectomy. We analyzed the differences between the bacterial pathogens in recurrent tonsillitis and semi-growth estimates with regard to age and tonsillar grade. Among 111 cases, 604 bacterial strains of 21 different from the tonsil superficial and core were isolated. The most common facultative anaerobic species isolated from the surface and core were Coagulase-negative staphylococci, Alpha-hemolytic streptococci and Diphtheroid bacilli in all subgroups except patients below 8 years old. The most commonly obligate anaerobic species isolated from the core were Propionibacterium acnes, Prevotella melaninogenica and Peptostreptococcus anaerobius. We found no significant difference in the cultured bacteria with respect to age and tonsillar size. The study subgroups did not differ in the occurrence of semiquantitative growth estimates of 3-4+. Our study demonstrates that there is polymicrobial aerobic and anaerobic flora in tonsils with regardless of patient's age and tonsillar size. This polymicrobial spectrum of bacteria may contribute to recurrence and to the failure of conservative treatment of these cases and therefore leads to surgical therapy.

- The intracellular bacteria Chlamydia hijack peroxisomes and utilize their enzymatic capacity to produce bacteria-specific phospholipids.
- Boncompain G1, Müller C2, Meas-Yedid V3, Schmitt-Kopplin P2, Lazarow PB1, Subtil A1.Author information 1Institut Pasteur, Unité de Biologie des Interactions Cellulaires, Paris, France ; CNRS URA 2582, Paris, France.2Department of BioGeoChemistry and Analytics, Institut für Ökologische Chemie, Helmholtz Zentrum München, Neuherberg, Germany.3CNRS URA 2582, Paris, France ; Institut Pasteur, Unité Analyse d'images quantitative, Paris, France.AbstractChlamydia trachomatis is an obligate intracellular pathogen responsible for loss of eyesight through trachoma and for millions of cases annually of sexually transmitted diseases. The bacteria develop within a membrane-bounded inclusion. They lack enzymes for several biosynthetic pathways, including those to make some phospholipids, and exploit their host to compensate. Three-dimensional fluorescence microscopy demonstrates that small organelles of the host, peroxisomes, are translocated into the Chlamydia inclusion and are found adjacent to the bacteria. In cells deficient for peroxisome biogenesis the bacteria are able to multiply and give rise to infectious progeny, demonstrating that peroxisomes are not essential for bacterial development in vitro. Mass spectrometry-based lipidomics reveal the presence in C. trachomatis of plasmalogens, ether phospholipids whose synthesis begins in peroxisomes and have never been described in aerobic bacteria before. Some of the bacterial plasmalogens are novel structures containing bacteria-specific odd-chain fatty acids; they are not made in uninfected cells nor in peroxisome-deficient cells. Their biosynthesis is thus accomplished by the metabolic collaboration of peroxisomes and bacteria.

Exemplarily the production of isobutyric acid was demonstrated in Escherichia coli with remarkable titers and yields. However, these examples suffer from byproduct formation due to the fermentative growth mode of the respective organism. We aim at establishing a new aerobic, chassis for the synthesis of isobutyric acid and other interesting metabolites using Pseudomonas sp. strain VLB120, an obligate aerobe organism, as host strain.
