“…The ability of microorganisms to carry out the ␤-decarboxymethylation reaction sequence (Fig. 2) was originally established by Seubert (46); the net effect of this process is to replace a methyl substituent (which prevents ␤-oxidation) with a carbonyl oxygen (Fig. 2).…”

Biodegradation of (E)-phytol [3,7,11,15-tetramethylhexadec-2(E)-en-1-ol] by two bacterial communities isolated from recent marine sediments under aerobic and denitrifying conditions was studied at 20°C. This isoprenoid alcohol is metabolized efficiently by these two bacterial communities via 6,10,14-trimethylpentadecan-2-one and (E)-phytenic acid. The first step in both aerobic and anaerobic bacterial degradation of (E)-phytol involves the transient production of (E)-phytenal, which in turn can be abiotically converted to 6,10,14-trimethylpentadecan-2-one. Most of the isoprenoid metabolites identified in vitro could be detected in a fresh sediment core collected at the same site as the sediments used for the incubations. Since (E)-phytenal is less sensitive to abiotic degradation at the temperature of the sediments (15°C), the major part of (E)-phytol appeared to be biodegraded in situ via (E)-phytenic acid. (Z)- and (E)-phytenic acids are present in particularly large quantities in the upper section of the core, and their concentrations quickly decrease with depth in the core. This degradation (which takes place without significant production of phytanic acid) is attributed to the involvement of alternating β-decarboxymethylation and β-oxidation reaction sequences induced by denitrifiers. Despite the low nitrate concentration of marine sediments, denitrifying bacteria seem to play a significant role in the mineralization of (E)-phytol.

“…by its cultural, morphological and biochemical characteristics. The organism was grown on Seubert's mineral medium [14], supplemented with the aromatic substrate (0.1%, w/v) as the sole source of carbon and energy, on a rotary shaker at room temperature (around 25°C). Stock cultures were maintained on mineral salts isophthalate-agar slants.…”

“…It is a non-motile, Gram-positive coccus and is oxidase, catalase-and nitrate reduction-positive, whereas it failed to hydrolyse both starch and gelatin and did not produce indole. The organism was grown on Seubert's mineral medium [12] supplemented with 0.25% isophthalic acid as the sole source of carbon in 500 ml erlenmeyer flasks on a rotary shaker at room temperature (around 25°C). Stock cultures were maintained on agar (2%) slants of the same medium.…”
