Fourier transform mid-infrared (MID-FTIR) spectroscopy coupled with partial least square algorithm (PLS-1) was used to predict total fat, fatty acid composition, and nutritional parameters as content of omega-3/100 g fish, fish lipid quality index (FLQ index) Atlantic bluefin tuna, crevalle jack, Spanish mackerel chilled fillets. Chemometric model developed 84 samples from the 3 species at different season capture varying storage times. The performance regression evaluated according...
Two Gram-negative, aerobic, non-motile, rod-shaped bacterial strains, FH13T and FH23, representing a novel group of Rhizobium isolated from root nodules Phaseolus vulgaris in Mexico, were studied by polyphasic analysis. Phylogeny 16S rRNA gene sequences revealed them to be members the genus related most closely 'Rhizobium anhuiense' CCBAU 23252 (99.7 % similarity), leguminosarum USDA 2370T (98.6 %), sophorae 03386T others ( ≤ 98.3 %). In sequence analyses housekeeping genes recA, glnII atpD,...
Yeasts were quantified and isolated from the rhizospheres of 5 plant species grown at 2 sites a Mexican region contaminated with arsenic, lead, other heavy metals. Yeast abundance was about 10(2) CFU/g soil 31 isolates obtained. On basis phylogenetic analysis 26S rRNA internal transcribed spacer fragment, 6 identified within following genera: Cryptococcus (80.64%), Rhodotorula (6.45%), Exophiala Trichosporon (3.22%), Cystobasidium (3.22%). spp. predominant group. Pectinases (51.6%),...
The Burkholderia cepacia complex (Bcc) comprises a group of 24 species, many which are opportunistic pathogens immunocompromised patients and also widely distributed in agricultural soils. Several Bcc strains synthesize strain-specific antagonistic compounds. In this study, the broad killing activity B. cenocepacia TAtl-371, strain isolated from tomato rhizosphere, was characterized. This exhibits remarkable antagonism against bacteria, yeast fungi including other strains,...
A Gram-stain-positive, aerobic, non-motile, coccoid, arsenic-resistant actinobacterial strain, designated CM1E1T, was isolated from the lateral root tissue of Prosopis laegivata grown on a mine tailing in San Luis Potosi, Mexico. Phylogenetic analysis based 16S rRNA gene sequences revealed that strain CM1E1T clustered closely with species genus Kocuria, and showed highest sequence similarity 98.7 % to Kocuria rhizophila TA68T. The DNA G+C content 74.5 mol% (Tm). major fatty acids were...
