“…Furthermore our results are better than those reported by Zakaria, et al [36] who obtained values of pH equal to 5 and 1 % of lactic acid when evaluating a silage made from scampi (Nephrops norvegicus) waste supplemented with 10 % of glucose as carbon source [36]. Likewise, it was reported that fermented shrimp wastes with glucose [37] and sucrose [38] both in concentration of 10 % were able to reach pH values of 4.6 using 10 % of Lactobacillus spp. B2 as inoculum.…”

Article HistoryThe aim of this study was to demonstrate the utilization of mango and fish wastes in biological silage production. Six treatments containing different levels of fish and mango wastes, sugar cane molasses and corn stover were inoculated with 4 % of Lactobacillus sp. B2 strain and incubated 15 days at 30 °C. The pH values of silages varied from 4.39 to 4.70 and the lactic acid content between 2.96 to 4.42 %. Silages showed the best acidifying at 7 day of fermentation; also they further increased the lactic acid bacteria counts and decreased the coliforms bacteria. Crude protein, ethereal extract and minerals values were higher in treatments with the upper level of fish wastes. The silage with the higher corn stover showed the upper crude fiber value and the lower in vitro dry matter digestibility. Contrary, the high inclusion level of fish wastes resulted in the highest dry matter digestibility. In conclusion, the combination of fish and mango wastes is a good alternative to produce biological fish silage as an ingredient for ruminants feed. The process of production is simple and environmental friendly. Contribution/Originality:The present study contributes to knowledge in the use of mango and fish wastes to produce silage. The findings show that silage can be evaluated in ruminants feeds for increase the added value and avoid the environmental impact of waste landfill sites.

“…Inoculation of suitable lactic acid bacteria ensures rapid acidification and eventual predominance of desired micro-flora able to conduct fermentation processes (Rao, Munoz, & Stevens, 2000). As noted by Rao et al (2000) fermentation of shrimp waste with L. plantarum inoculum resulted in a high-quality protein liquor output when compared with solely acid fermentation (Shirai et al, 2000) The extraction of chitin from freshwater shrimp waste by fermentation may present as a limitation the occurrence of smaller % DM and % DP values when compared to the chemical treatment that has about 100% efficiency (Arantes et al, 2015). This fact is also noted in the literature for shrimp waste from marine species where 98% DM and 78% DP after 10 days of fermentation with L. helveticus (Arbia et al, 2013); 91% DM and 97% DP, after 7 days of fermentation with L. acidophilus (Duan et al, 2012); DM ranging from 63 to 81% and DP of 60 the 83%, with L. plantarum (Rao & Stevens, 2005;2006).…”

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.

“…One interesting new technology for extraction of chitin that offers an alternative to the more harsh chemical methods is fermentation by using microorganisms. Fermentation has been envisaged as one of the most ecofriendly, safe, technologically flexible, and economically viable alternative methods [22][23][24][25][26][27][28]. Fermentation of shrimp waste with lactic acid bacteria results in production of a solid portion of chitin and a liquor containing shrimp proteins, minerals, pigments, and nutrients [26,29].…”

Chitin is a big molecule composed of -beta-1,4-N-acetylglucosamine (GlcNAc) monomers. There are three forms of chitin: , , and chitin. The -form, is mainly obtained from crab and shrimp. Both and chitin/chitosan are commercially available [5]. Sources of chitinIn the book "Chitin" published by Muzarelli in 1977, we can find a complete list of organisms that contain chitin: Fungi, Algae, Cnidaria (jellyfish), Aschelminthes (round worm), Entoprocta, Bryozoa (Moss or lace animals, Phoronida (Horseshoe worms), Brachiopoda(Lamp shells), Echiruda, Annelida (Segmented worms), Mollusca, Arthropoda and Ponogophora [6]). Herring, P.J in 1979 wrote that chitin is the main component of arthropod exoskeletons, tendons, and the linings of their respiratory, excretory, and digestive systems, as well as insects external structure and some fungi. It is also found in the reflective material (iridophores) of both epidermis and eyes of arthropods and cephalopods (phylum: Mollusca) and the epidermal cuticle of the vertebrate Paralipophrys trigloides (fish) is also chitinous [7,8]. The main commercial sources of chitin are the shell wastes of shrimp, lobsters, crabs and krill. There are three forms of chitin: , , and chitin. The -form, is composed of alternating antiparallel polysaccharide strands and is mainly obtained from crab and shrimp. -Chitin is by far the most abundant; it occurs in fungal and yeast cell walls, krill, lobster and crab tendons and shells, shrimp shells, and insect cuticle. The rarer -chitin is composed of parallel strands of polysaccharides, is found in association with proteins in squid pens [9,10] and in the tubes synthesized by pogonophoran and vestimetiferan worms [11,12]. It also occurs in aphrodite chaetae [13] as well as in the lorica, built by some seaweeds or protozoa [14,15,16]. And 2 parallel chains alternating with an antiparallel strand constitute gamma chitin and are found in fungi [15].
