RESUMO
The efficiency of the termite Macrotermes bellicosus at digesting lignocellulose is due to its gut bacterial symbionts. We report the metagenome-assembled genome sequence of Burkholderia cepacia UJ_SKK_1.2, reconstructed from metagenomes produced from Macrotermes bellicosus gut microbiota. The 7,460,271-bp genome obtained consists of 6,763 protein-coding sequences, with 6,719 functionally assigned genes and 59 RNA genes.
RESUMO
The metagenome-assembled genome (MAG) sequence of Stenotrophomonas maltophilia strain UJ_SKK_5.5 was obtained from the gut microbiome of Macrotermes bellicosus (termite) from hot, arid Nigeria. The assembled genome (4,313,335 bp) contains 157 contigs, the N50 is 41,072 bp, the GC content is 66.57%, and there are 3,925 protein coding sequences, 3,886 proteins with functional assignments, 39 pseudogenes, and 67 RNA genes.
RESUMO
The metagenome-assembled genome sequence of Olivibacter sp. strain UJ_SKK_5.1 was generated from the metagenome of a Macrotermes bellicosus (termites) gut collected from Nigeria's hot, arid environment. The assembled genome (6,135,249 bp) contains 432 contigs, with an N50 value of 22,779 bp, GC content of 41.1%, 5,043 protein-coding sequences, 5,034 proteins with functional assignments, and 9 pseudogenes and 48 RNA genes.
RESUMO
While antimony has been reported to migrate from PET bottles into contents, reports on bottled water and soft drinks usage and PET bottle reuse patterns are currently unavailable in the literature. Bottle use conditions and patterns are important determinants of antimony migration. In this work a survey assessing the pattern of bottle use and reuse in Britain and Nigeria was undertaken. The survey findings influenced the design of laboratory experiments that assessed the migration of antimony from PET bottles into water and soft drinks. Typical storage durations for bottled contents between purchase and opening for use were 7 days or less. However storage of up to one year was reported. Bottle reuse was high and similar for the two countries with reuse durations being higher in Nigeria. The antimony concentration in 32 PET bottle materials from Britain and Nigeria were similar and ranged between 177 and 310 mg kg(-1). For 47 freshly purchased British bottled contents antimony concentration ranged between 0.03 and 6.61 µg L(-1) with only one sample exceeding the EU acceptable limit. Concentrations of Cd, Ge, Zn, Al, Be, Ti, Co and Pb were also measured. At realistic temperatures of 40 and 60 °C antimony concentration in deionised water in bottles remained below the EU acceptable limit even after 48 h exposure. The limit was exceeded for most exposures at 80 °C. Concentration of antimony in some bottled contents exceeded the EU limit after 11 months of storage at room temperature. Bottle aging and increase in bottle volume were associated with decreased migration of antimony from bottles.
