The bioremediation of petroleum contaminated soil was investigated using a laboratory scale aerated reactor. The Indigenous bacteria, Stenotrophomonas multophilia, were isolated from the contaminated sites near to Jordan Petroleum Refinery and used further in the bioremediation experiments. First order kinetic equation has been proven to satisfactorily describe the biodegradation of petroleum contained in soil in the presence of the isolated bacteria. The results also showed that the first order kinetic constants for the different bioreactors vary between 0.041 and 0.0071/ day. The overall kinetic constant k′ was determined based on food-to-microorganisms ratio and found to be 0.02/day.

“…T. otitidis is part of the normal flora of the ear (15,29,51) that may cause opportunistic infections such as acute otitis media (8,16,17,44,45,48). However, in contrast to reports that it is an exclusively otic organism, it has also been isolated in a case of bacteremia (33) and from environmental sources (49). T. otitidis apparently shares other cell envelope features with the mycolata.…”

Characterization of a Truncated Lipoarabinomannan from the Actinomycete Turicella otitidis

et al. 2005

Lipoarabinomannan (LAM) lipoglycans have been characterized from a range of mycolic acid-containing actinomycetes and from the amycolate actinomycete Amycolatopsis sulphurea. To further understand the structural diversity of this family, we have characterized the lipoglycan of the otic commensal Turicella otitidis. T. otitidis LAM (TotLAM) has been determined to consist of a mannosyl phosphatidylinositol anchor unit carrying an (␣ 136)-linked mannan core and substituted with terminal-arabinosyl branches. Thus, TotLAM has a novel truncated LAM structure. Using the human monocytic THP-1 cell line, it was found that TotLAM exhibited only minimal ability to induce tumor necrosis factor alpha. These findings contribute further to our understanding of actinomycete LAM diversity and allow further speculation as to the correlation between LAM structure and the immunomodulatory activities of these lipoglycans.The cell envelopes of gram-positive bacteria contain structurally diverse macroamphiphilic membrane-anchored polymers that can be classified as either lipoteichoic acids or lipoglycans (11,54,56). Although considered to play important roles, the functions of these macromolecules remain unknown and it is not known if a common function underlies their structural diversity. Lipoteichoic acids predominate in the Bacillus-Streptococcus-Clostridium (Firmicutes) lineage of grampositive bacteria, whereas Mollicutes and actinomycete bacteria typically synthesize lipoglycans (54). Actinomycete lipoglycans can be classified into a number of structural archetypes (54), of which the most extensively studied are the mycobacterial lipoarabinomannans (LAM) (6,7,39). LAM-like lipoglycans have also been identified in phylogenetically close relatives of the mycobacteria, which share common cell envelope features dominated by the presence of mycolic acids (13,52,55), and three lipoglycans from this taxon (the mycolata) have been recently characterized as structurally related members of a LAM family: ReqLAM from the equine pathogen Rhodococcus equi (18), RruLAM from Rhodococcus ruber (22), and TpaLAM from Tsukamurella paurometabola (20). Moreover, an additional representative of the LAM family (AsuLAM) has been characterized from the more distantly related actinomycete Amycolatopsis sulphurea (21), which lacks mycolic acids. In each of the LAM-like lipoglycans, the carbohydrate domain consists of a linear (␣ 136) mannan backbone and an arabinan portion either consisting of few units glycosylating the mannan core or organized as an independent domain, as observed in mycobacteria.The mycolata lineage also encompasses a few species that appear to have lost the ability to synthesize mycolates, including Turicella otitidis, the type species of the monospecific genus Turicella (16, 17). T. otitidis is part of the normal flora of the ear (15, 29, 51) that may cause opportunistic infections such as acute otitis media (8,16,17,44,45,48). However, in contrast to reports that it is an exclusively otic organism, it has also been isolated in a case ...

“…In the case of the latter species, it has to be considered that strains reported in the literature as Corynebacterium xerosis are probably misidentified and correspond to the species Corynebacterium amycolatum . Turicella otitidis was isolated from patients with otitis media, a cervical abscess, and a composted pine bark biofilter (Funke et al 1994;Fernández-Pérez et al 1999;Strauss et al 2000).…”
