The use of the marine algae has showed a good performance as consolidant in textile structures. In this work show the results of the Pyropia Perforata algae as an alternative consolidant in deteriorated linen textile fibers. First, it was obtained a dry extract of the algae and was characterized by Fourier Transformed Infrarred Spectroscopy (FTIR). Were prepared consolidant solutions based on algae extract at 0.5%, 1.5% and 2.5% w/w, these consolidant solutions were applied on natural fiber linen specimens previously deteriorated. The specimens were assay by mechanical techniques for known the effect of the consolidant. The result show that the solution with 1.5% of algae extract content present the best mechanical behaviour. The Pyropia Perforata algae is a viable proposal to be used as consolidant of vegetal fibers.

“…Collagen was extracted from bovine split according to the method of our previous work . Based on our previous method , the γ‐PGA‐NHS esters were synthesized and the degree of esterification (DE), which was calculated by the ratio of the amount of carboxylic group reacted with HNS to the total carboxylic groups , were 2.8% and 5.8%, correspondingly defined as low and high degree of esterification (LDE or HDE), respectively.…”

The rheological behaviors of a polyanionic collagen, fabricated using poly(γ -glutamic acid)-N-hydroxysuccinimide (γ -PGA-NHS) as a novel modifier, were investigated in this study. It was found that both of the native and modified collagen solutions were pseudoplastic fluids, as shown from the steady-shear tests. While the storage modulus and loss modulus of collagen increased with increasing the amount of γ -PGA-NHS, or with increasing the degree of esterification of γ -PGA-NHS; meanwhile, the dynamic denaturation temperature determined by dynamic temperature sweep was also increased, indicating an improved thermal stability of collagen solution modified by γ -PGA-NHS. The creeprecovery measurements showed that the resistance to deformation was enhanced for modified collagen, probably due to the cross-linking occurred between the ε-amino groups of collagen molecules and α-COOH groups of γ -PGA-NHS, as well as the electrostatic interaction and hydrogen-bond interactions between the two molecules. Furthermore, the aggregation of collagen fibers was promoted due to these interactions between collagen and γ -PGA-NHS as observed by atomic force morphology. In addition, the modified collagen exhibited good cytocompatibility as demonstrated by cell growth culturing. The obtained information was expected to give valuable clues to the design and fabrication of controlled stable collagen-based products for applications in various biomedical fields.

“…Within these large waste volumes, the highest quantities of ready to use biomass. Particularly the seeds and peels are of major interest since they contain lower moisture content than the original fruit 3 . Citrus fruits such as orange and tangerine have great importance due to their high production in the world 4 and, specially, in Mexico 5 .…”

“…The main advantage of reprocessing second-generation biomasses is that they don’t generate a cost when used as raw materials. It has been reported that citrus peels are great source of pectin 4 , 10 – 12 , including tamarind seeds 13 and mango peels 3 , 14 – 17 . Many studies have reported different variables in the extraction process of pectin.…”

A 23 factorial design was used to evaluate the influence of temperature, catalyst and time and esterification degree (DE) of pectin obtained from mango, orange and tangerine peels as well as tamarind seeds by using the acid hydrolysis method. The study showed that a high temperature positively influenced the percentage of pectin yield for the four second generation biomasses. Nevertheless, the temperature showed a greater influence in the solubility and diffusion of the acid solvent in the tamarind seed matrix, resulting a pectin recovery 32.9%. Concerning the %DE, the most statistically significant value observed was dependent on the type of biomass studied. The %DE and the nature of the pectin are determining factors in the pectin’s final use, in the present work the pectin extracted was used to produce furfural, a precursor of high value chemicals. The furfural production was achieved through alkaline hydrolysis and enhanced using the Maillard reaction, reaching a maximum concentration of 71.8 g/L which represents a 42.1% increase from the alkaline hydrolysis.
