an effective antagonist of plant pathogens such as Pythium aphanidermatum and Fusarium oxysporum f. sp. radicis-lycopersici. Oligonucleotide usage signatures of the P. alloputida KT2440 genome Di- to pentanucleotide usage and the list of the most abundant octa- to tetradecanucleotides are useful measures of the bacterial genomic signature. The P. putida KT2440 chromosome is characterized by strand symmetry and intrastrand parity of complementary oligonucleotides. Each tetranucleotide occurs with similar frequency on the two strands. Tetranucleotide usage is biased by G+C content and physicochemical constraints such as base stacking energy, dinucleotide propeller twist angle, or trinucleotide bendability. The 105 regions with atypical oligonucleotide composition can be differentiated by their patterns of oligonucleotide usage into categories of horizontally acquired gene islands, multidomain genes or ancient regions such as genes for ribosomal proteins and RNAs. A species-specific extragenic palindromic sequence is the most common repeat in the genome that can be exploited for the typing of P. putida strains. In the coding sequence of P. putida, LLL is the most abundant tripeptide. Phylogenomic analysis reclassified the strain KT2440 in a new species Pseudomonas alloputida. Organic synthesis Pseudomonas putida's amenability to genetic manipulation has allowed it to be used in the synthesis of numerous organic pharmaceutical and agricultural compounds from various substrates. CBB5 and caffeine consumption Pseudomonas putida CBB5, a nonengineered, wild-type variety found in soil, can live on caffeine and has been observed to break caffeine down into carbon dioxide and ammonia.
