Marine macroalgae, Kappaphycus alvarezii has economic importance which is considered as the main source of Kappa carrageenan, a hydrocolloid used in various industries as an emulsifying agent and stabilizer. In the production process of this raw material, the fresh seaweed is subjected to grinding and filtering process, yielding a wet solid fraction rich in carrageenan and other liquid fractions. The latter has been studied for its use in pulverization of bean leaves, wheat, soybean, rice, among others. Several reports have shown positive effects on the growth, yield and quality of vegetables and grains treated with the extract of this alga. However, there are few reports on the use of the liquid extract of K. alvarezii for seed treatment, and also of its use in conjunction with the solid fraction of seaweed. In this context, this study aims to evaluate the physiological quality of soybean seeds treated with liquid extract of this alga and, with the mixture of liquid extract and solid biomass, submitted to a hydrolysis process. Two soybean seed treatment tests were performed in laboratory: one treatment contained pure liquid extract (100%) while the other was mixed with two samples of solid biomass hydrolyzed with concentrations of 25 and 75%. For comparison of their results, there was a positive control treatment and one negative control treatment. The results showed that, within the present working conditions, treatments with seaweed extract can increase the length of the aerial part of the seedling up to 28% and the length of the primary root up to 19% as compared to the negative control; thus, it improves the physiological performance of seeds.
Food security is essential because it is directly related to human health and well-being. When food is contaminated by bacteria, fungi, parasites, chemicals or foreign bodies, it can cause a range of illnesses, from mild food poisoning to serious illnesses that can lead to death. Foodborne illnesses (EDDs) arising from the consumption of such contaminated food are substantially relevant to public health. Its occurrence systematically triggers damages to various spheres of society, including the economic sector, due to absenteeism, compromise of trade and depletion of industrial activities. Thus, food hygiene, in recent years, has been the subject of increasing interest. Objective: To review the literature regarding the microbiological profile of foods marketed in the state of Pernambuco. Literature Review: Regarding the bacterial profile, the studies included in this review identified contamination in the samples in the following proportions: fecal coliforms (20%), Salmonella (55%), Escherichia coli (72%), Staphylococcus genus (71%), Listeria monocytogenes (25%). Regarding the mycological profile, contamination by Aspergillus flavus (70%), Penicillium (60%), Fusarium (80%), Aspergillus parasitic us (80%) was identified. In addition, bacterial and fungal toxins were identified in 65% of the samples. Final considerations: The presence of different bacteria and fungi with pathogenic potential, in addition to their toxins, in foods marketed in Pernambuco reflect the importance of promoting good food handling practices as a preventive strategy for DTA.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
