The continuous growth of poultry industry results in an increased amount waste provided from both production facilities and processing plants. meat massive quantities solid as feathers, viscera, bones, dead on arrival. use enzymes for bioconversion such byproducts into materials with value is interesting strategy. Enzymes can be useful to convert feed fertilizers. hydrolysis animal also generate bioactive peptides, which are important molecules that may exert physiological effects vivo,...
C-phycocyanin (C-PC) is a protein with bioactive properties, which found mainly in cyanobacteria and that used as natural food dye. Even though it extensively studied, few authors have reported C-PC's colour stability antioxidant activity when applied to matrices. Therefore, the aim of this research was evaluate over time capacity grade C-PC extract milk-based ice creams. The C-PC-added creams showed insignificant loss during 182 d. Regarding activity, presented low ABTS●+ peroxyl radicals...
C‐phycocyanin (C‐PC) is a natural blue dye, and depending on its purity, which measured by the ratio between absorbance of chromophore (A 620 ) proteins 280 ), it can be used in food (purity > 0.7), cosmetics 1.5), therapeutic treatments 4.0). Several physical, chemical, enzymatic methods extraction are reported, however, few able to extract C‐PC with purity above 0.7. An innovative method grade from wet Spirulina platensis biomass proposed. The cells were pretreated...
This work presents a study of industrially applicable techniques to obtain biologically supported carbon dioxide capture system, based on the extraction carbonic anhydrase from bovine blood. Carbonic is metalloenzyme which catalyzes reversible hydration dioxide. The objective this was establish conditions erythrocytes and apply it in To achieve this, two different purification were evaluated: one by with organic solvents chloroform ethanol, where solvent proportions studied; other ammonium...
C-phycocyanin is a natural blue dye extracted from Spirulina platensis, which has many applications in the food and pharmaceutical industries. In this paper effect of pH temperature on adsorption onto two different ion exchange resins (Streamline DEAE Streamline Q XL) for expanded bed chromatography was investigated. Moreover, kinetics isotherm were evaluated. The equilibrium XL matrix reached after 60 min, while it only 140 min. showed highest partition coefficient at 7.5 both 25 ºC. very...
This study aimed to evaluate the influence of magnetic fields (MF) on inoculum cultivation and carotenoid production by Phaffia rhodozyma. The application MF in culture was evaluated (0 m T – control 30 T). Cellular concentration increased 12.8 % after 24 h-culture with compared assay, this best alternative for preparation inoculum. Different intervals were over 168 h. highest volumetric carotenoids achieved applying throughout cultivation, values 1146.39 ± 26.18 μg L−1 productivity 11.94...
C-phycocyanin (C-PC) is a phycobiliprotein that can be used as natural blue dye in the food and cosmetic industries, biomarker or an agent medical treatments, depending on its purity grade. Here we described for first time single-step purification process of C-PC extracted from wet biomass Spirulina (Arthrospira) platensis LEB-52 using ion exchange chromatography with pH gradient elution. Different conditions varying elution buffers volumes, loading addition salt buffer were studied. The...
Abstract C‐phycocyanin, a natural blue dye, stands out today because it has antioxidant, anti‐inflammatory, and anti‐tumor properties, can be extracted from cyanobacteria, such as the genus Spirulina . A process that received attention is adsorption of proteins in presence biomass by fluidized bed, particularly an expanded bed. Therefore, this study aimed at purifying C‐phycocyanin ion exchange chromatography bed with two different resins (Streamline Q XL Streamline DEAE) comparing...
Abstract The simultaneous production of carbonic anhydrase and the phycobiliproteins, C‐phycocyanin allophycocyanin, was evaluated during cultivation Spirulina platensis using Zarrouk's medium in its non‐diluted (100 % ZM) diluted to 20 (v/v) (20 forms. In both media, simultaneously produced phycobiliproteins. For phycobiliproteins’ production, higher concentrations (mg/g) allophycocyanin were obtained when 100 ZM used. (U/g) on 6 th day culture media. promoted greater productions these...
O potencial biotecnológico das microalgas vem despertando interesse devido a possibilidade de obtenção diversos bioprodutos, destacando-se C-ficocianina, aloficocianina e anidrase carbônica (AC). Para destes biocompostos faz-se necessário uma etapa ruptura celular. A influência do tempo celular (4, 6, 8, 10, 12 14 min) utilizando o homogeneizador ultrassônico na extração dos bioprodutos AC (em termos esterase hidratase) foi avaliada em duas concentrações Spirulina platensis LEB-52 (0,2 23...
Many investigators have employed honeybees or honeybee products (honey, wax, pollen) as tools for assessing environmental pollution in industrial areas. Several reports refer of their utility monitoring radionuclides heavy metal contamination. The objective this study was to investigate the potential impact on Biella area, located east Piedmont region. A survey 6 apiaries carried out, samples of: honey, beeswax, bees and pollen were collected analyzed for: pesticides PCB, neonicotinoides...
