Abstract:
Leafy vegetables could accumulate nitrate (NO3?) above limits safe for humans, hence it would be advisable to customarily determine their NO3? concentration. We wanted to develop a quick test to determine NO3? concentration in fresh tissue extracts and estimate the error of using this test to identify samples with NO3? concentrations above the World Health Organization (WHO) threshold. There was a positive linear relationship (P < 0.001) between NO3? concentrations determined by the quick test and by potentiometry in dry tissue extracts. Samples were classified as ?acceptable? or ?excessive? according to their potentiometric NO3? concentration, using a critical level of 75% (p) of the observed NO3? distribution. According to the Cate-Nelson model, the quick test identified as ?acceptable? from 5.6% to 15.4% of samples that were in the ?excessive? category. In spite of this error rate, the quick test use would improve consumers? protection, because no controls on vegetables NO3? concentration are available in Uruguay. |

ABSTRACT.
Streptomyces is a genus of gram-positive bacteria with a mycelial growth habit and the ability to produce spores. Due to their unparalleled ability to produce antibiotics, most of the early research carried out on Streptomyces was antibiotic discovery-driven, with over two thirds of antibiotics used for medical purposes originally isolated from Streptomyces . However, their ubiquity, high capacity of adaptation to different niches and rich secondary metabolite production, make them an invaluable source of solutions in diverse human activities, including medicine, agriculture, industry and toxic waste remotion. In addition to the ability to culture and produce Streptomyces and Streptomyces -derived metabolites, knowledge on how to manipulate natural populations of Streptomyces will likely improve our ability to make environmentally sustainable decisions. |
