“…The use of whey fermentation for the production of individual compounds such as ethanol, polyhydroxyalkanoates, methane, hydrogen, and films has been reviewed, although individually (Akaraonye et al 2010;Du et al 2012;Guimarães et al 2010;Hassan and Nelson 2012;Karadag et al 2014). Here, a compilation on the production of diverse individual products (including fuels and food additives) by fermentation using different microorganisms and methods is presented.…”

Whey, the main by-product of the cheese industry, is considered as an important pollutant due to its high chemical and biological oxygen demand. Whey, often considered as waste, has high nutritional value and can be used to obtain value-added products, although some of them need expensive enzymatic synthesis. An economical alternative to transform whey into valuable products is through bacterial or yeast fermentations and by accumulation during algae growth. Fermentative processes can be applied either to produce individual compounds or to formulate new foods and beverages. In the first case, a considerable amount of research has been directed to obtain biofuels able to replace those derived from petrol. In addition, the possibility of replacing petrol-derived plastics by biodegradable polymers synthesized during bacterial fermentation of whey has been sought. Further, the ability of different organisms to produce metabolites commonly used in the food and pharmaceutical industries (i.e., lactic acid, lactobionic acid, polysaccharides, etc.) using whey as growth substrate has been studied. On the other hand, new low-cost functional whey-based foods and beverages leveraging the high nutritional quality of whey have been formulated, highlighting the health-promoting effects of fermented whey-derived products. This review aims to gather the multiple uses of whey as sustainable raw material for the production of individual compounds, foods, and beverages by microbial fermentation. This is the first work to give an overview on the microbial transformation of whey as raw material into a large repertoire of industrially relevant foods and products.

A demanda energética é crescente no mundo moderno e o hidrogênio surge como uma fonte alternativa de energia limpa. Os resíduos agroindustriais apresentam grande concentração de material orgânico e seu lançamento pode comprometer a qualidade ambiental. Nesse sentido, a produção biológica de hidrogênio tem sido apontada como uma alternativa para o tratamento destes resíduos. O objetivo deste trabalho foi aplicar o resíduo agroindustrial de laticínios e os resíduos sintéticos de lactose e soro do queijo em reatores anaeróbios em batelada sob temperatura termófilas para a produção biológica de hidrogênio. O efluente sintético de lactose mostrou melhor desempenho com taxa de produção máxima e rendimento específico de hidrogênio de, respectivamente, 21.65 mmolH2/dia e 1,84molH2/mol de carboidratos . Etanol e ácido acético foram os metabolitos solúveis de maior concentração, o que indica que a rota da produção de hidrogênio foi a do etanol. A produção a partir do efluente bruto de laticínios mostrou-se satisfatória.Palavras-chave: hidrogênio, reatores anaeróbios, laticínios.

“…Infact, hydrogen only produces water and traces of N oxides, when used in combustion systems, while producing only water, when used with electrochemical systems (fuel cells). Bio-hydrogen production is depending on various elements such as feedstocks composition, microbial inocula, pretreatments, pH, temperature (Hawkes et al, 2002;Kim et al, 2006;Karadag and Puhakka, 2010;Karadag et al, 2014).…”

“…CW is rich in lactose and minerals, along with a chemical oxygen demand (COD) concentration up to 80 g L −1 , therefore, it was considered an valid ingredient for bioenergy production (Sansonetti et al, 2009;Hublin and Zelic, 2013;Perna et al, 2013;Karadag et al, 2014). In Italy, a large amount of CW is produced yearly, also deriving from buffalo mozzarella cheese (4th DOP cheese as production), together with "scotta", a deproteinized by-product, obtained after the production of both cheese and "ricotta" (similar to cottage cheese product, widespread in Anglo-saxon country) (Vasmara and Marchetti, 2017).…”

Biogas production from agricultural and industrial wastes delivers two benefits: on one side, the treatment of organic residues prevents the environmental and economic impact of their disposal; on the other side, methane and/or hydrogen are generated. The aims of this study were both to produce bio-hydrogen from buffalo wastes and to investigate the relationship between biogas production and bacterial and archaeal community composition. Anaerobic codigestion of livestock by-products (buffalo sludge and low protein cheese whey-scotta), with buffalo rumen and buffalo sludge as inoculum, was performed. The microbial community was analyzed using next-generation sequencing of 16S rRNA gene amplicons. Codigestion showed to be positive because of both sludge buffering capability and highly degradable carbohydrates content in scotta. Rumen inoculum proved more efficient compared to sludge during fermentation. In fact, cumulated production was higher (120.8 vs. 65.4 ml H 2 g VS −1 respectively) and the average percentage of hydrogen in biogas was 48.1 (v/v) with maximum peak at 64.6. Moreover, rumen bacterial profile showed higher genera richness. Taxonomic classification showed that among the bacteria, Firmicutes, 23.3% of whom Clostridia; Bacteroidetes, and in particular Bacteroidia; Proteobacteria and Tenericutes, accounted for 88.2% of total sequences. Concerning the Clostridia Family XIII, the C. Incertae Sedis was the most represented (6.6%), and its quantity was twice as much in rumen inoculated hydrogen-producing samples than those non-producing. In the archaeal, community predominated the phylum Euryarcheota, with Methanobrevibacter the most represented, which was higher when hydrogen was produced with rumen inoculum. Studies on buffalo rumen as inoculum for hydrogen production are limited and this paper gives a first overview of microbial community composition by NGS in producing and non-producing samples.
