“…The processing done by the fishermen should drastically reduce the percentage of proteins in the residue. With regard to SWM, it contained calcium levels (37.00%) slightly higher than those determined by Silva et al (2010) for shells of Crassostrea gigas and Perna perna, which varied between 33.00 and 34.80%, and similar to those presented by Rostagno et al (2005) for limestone (38.40%), the main source of traditional calcium in non-ruminant animal diets. The use of waste from the processing of aquatic organisms from fisheries or aquaculture has increased due to environmental and economic issues.…”

A diagnosis was made on the fishing, processing, commercialization and generation of residues of the sururu fishery in Mundaú lagoon, Maceió-AL. Thirty nine fishermen were interviewed and also incursions were made for observations. Furthermore, sururus were collected to perform biometry. Residue of the sururu processing was collected to the fabrication of sururu waste meal (SWM), posteriorilly its bromatological composition was analysed. Fishermens of sururus fish 4.56 times week-1 and each fishing excursion lasts 5h26min, yielding 18.61 cans (18.61 to 37.22 kg soft tissue). Besides the sururus, 77.92% also catch fish, shrimp, and other organisms to complement the income. Average selling price was R$ 6.92 per kg of edible and CPUE from 3.42 to 6.85kg edible day-1. The average size and weight are 33.21 mm and 1.62 g, with 782.53 g of waste being generated to produce 1.0 kg of meat. SWM contained 37.00% calcium. It was verified that there is a need to create a management plan capable of reducing environmental impact in the lagoon, implement fishing programs and waste management, as well as improve the structure for the processing of that mollusc. Studies of the use of SWM as a source of calcium in diets are also recommended.

“…The infrared spectra obtained for the fermentation product, chitin and chitosan (Figure 3) reveal bands characteristic of the biopolymers and the differences between them: an axial stretch band of OH between 3440 the 3480 cm Evaluation of the fermentation product by DRX (Figure 4) indicates amorphous halos of α-chitin in 2Ɵ = 9 and 19º which are typically observed in this biopolymer, and the presence of minerals characterized by crystalline peaks at 2Ɵ = 23.2, 29.5 and 39.6°, typical of the crystalline phase of calcium carbonate (CaCO 3 ) (Silva & Debacher, 2010;Rezaei, Mohadesi, & Moradi, 2013 The diffractogram in Figure 4 is consistent with the type of chitin obtained by fermentation, since demineralization was incomplete and peaks attributed to minerals present initially in the carapace of shrimps still remain. …”

ABSTRACT. Freshwater shrimp shells from the shrimp farming activity in tanks, were processed for biological extraction of chitin, by fermentation with Lactobacillus plantarum isolated from meat products, offering an advantageous demineralization and deproteination of the residue, replacing the chemically. Deproteination was obtained approximately 99% and demineralization of up to 87% using batch fermentations with a maximum of 72 hours and the use of simple strategies such as pH adjustment and reinoculation. The performance of chitin was about 40% greater than in the chemical extraction and the results indicate an interesting method in the process of production of chitosan, where the biopolymer chitin is precursor.Keywords: shrimp shells, chitosan, Lactobacillus plantarum, bioprocess.Otimização de fermentação lática para extração de quitina de resíduos de camarão de água doce RESUMO. Carapaças de camarão de água doce provenientes da atividade de carcinicultura em tanques foram processadas para extração biológica de quitina, por meio da fermentação com Lactobacillus plantarum isolado de produtos cárneos, oferecendo uma via vantajosa de desmineralização e de desproteinização do resíduo, em substituição à via química. Obteve-se desproteinização de cerca de 99% e desmineralização de até 87% por intermédio de fermentações em batelada com duração máxima de 72 horas e o uso de estratégias simples, como ajuste de pH e reinoculação. O rendimento de quitina foi cerca de 40% maior do que na extração química, e o conjunto dos resultados indica um método interessante no processo de produção de quitosana, em que o biopolímero quitina é precursor.Palavras-chave: carapaças de camarão, quitosana, Lactobacillus plantarum, bioprocesso.

“…On the other hand, the strong and wide band of 1420 cm −1 is characteristic of asymmetric vibration of CO that is also associated to the strong and wide band of 874 cm −1 due to out‐of‐plane angular deformation of group CO 3 vibration. Both wide bands belong to calcium carbonate in calcite phase, as communicated by several groups that have been studying the calcium carbonate polymorphs . It is evident that the paper sludge as received from the paper mill contains calcium carbonate that is removed with the above‐mentioned reaction with hydrochloric acid solution delivering a clean surface of that short fiber cellulose that is no more useful for making new paper or paper‐derivative products.…”

Hybrid Cellulose–Silica Materials from Renewable Secondary Raw Resources: An Eco‐friendly Method

et al. 2018

View full text Add to dashboard Cite

Hybrid organic–inorganic materials based on cellulose matrix and silica particles are obtained from wastes of the local paper recycling mill and sugarcane mill as renewable secondary raw materials. The performance comparison of these hybrid materials made from secondary raw materials against the materials made from pure, raw sources is discussed. The Fourier transform infrared spectra show that cellulose features prevail even at 43 wt% silica nanoparticles in the hybrid materials. Such a high content of silica originated from sugarcane bagasse ash and hollow glass microspheres contributes to the high thermal stability of the final composites, as seen by thermogravimetric analysis with very low water absorption. This one‐step approach of biobased hybrid materials represents an excellent way to produce high‐performance materials with high content of inorganic nanoparticles for a wide variety of applications like energy efficient building material completely cement‐free.
