“…The identification of aeration and agitation speed as controlling variables agrees well with the literature referred to the production of extracellular biopolymers through microbial fermentation [58][59][60]. Moreover, the strong effect of aeration on production of C. maltosa SM4 biomass is in agreement with previous reports on other Candida species [61,62]. It can be explained by the fact that both aeration and agitation increase the amount of dissolved oxygen and help to disperse nutrients and other substances in the medium, which results in higher microbial growth, and thus, more cell biomass formation.…”

Candida maltosa was cultivated in the liquid phase of residual brewing yeast, a major brewery residue, to produce biomass and biofilm. Using response surface methodology, the effect of two variables at two different levels was investigated. The independent variables were agitation speed (at 100 and 200 rpm), and aeration (at 1 and 3 L min−1). Aeration was identified to be important for the production of both biomass and biofilm, while agitation was the only factor significantly affecting biofilm production. The maximal production of biofilm (2.33 g L−1) was achieved for agitation of 200 rpm and aeration of 1 L min−1, while the maximum for biomass (16.97 g L−1) was reached for 100 rpm agitation and 3 L min−1 air flow. A logistic model applied to predict the growth of C. maltosa in the exponential phase and the biofilm production, showed a high degree of agreement between the prediction and the actual biomass measured experimentally. The produced biofilms were further characterized using Fourier-transform infrared spectroscopy (FTIR), Scanning Electron Microscopy (SEM) and Thermogravimetric Analysis (TGA). FTIR allowed the identification of methyl, carbonyl ester and sulfate groups, and revealed the presence of uronic acid moieties and glycosidic bonds. Water-retention ability up to relatively high temperatures was revealed by TGA, and that makes the produced biofilm suitable for production of hydrogels. SEM also gave indications on the hydrogel-forming potential of the biofilm.

“…The present study shows that CRHH and DDG rice husk contain three amino acids, methionine (0.45-0.54%), cysteine (0.37-0.65%), and tryptophan (0.21-0.16%), at the lowest concentrations compared to the other amino acids. Dimova et al (2014) also reported that a biomass of C. tropicalis cultivated in hydrolysed wheat bran, oat bran and rice husk media was poor in methionine and cysteine. Onofre et al (2017) also reported that cysteine and tryptophan were at the lowest concentrations of the amino acids in a biomass of S. cerevisiae cultivated in a beer manufacturing process.…”

“…The content of certain amino acids increased, especially lysine, isoleucine, asparagine and glutamine, due to the amino acid contribution of the yeast cell mass. Dimova et al (2014) reported that a biomass C. tropicalis cultivated in hydrolysed wheat bran, oat bran and rice husk media was rich in lysine, isoleucine, glutamic acid and aspartic acid. Onofre et al (2017) reported that glutamine and asparagine were the highest among amino acids in a biomass of S. cerevisiae cultivated in a beer manufacturing process.…”

Aims: Distillers dried grains are the nutrient rich co-product of dry-milled ethanol production. The present study aimed to prove that the nutritional composition of distillers dried grain from a crude hydrolysate of rice husk fermented by cocultures of Saccharomyces cerevisiae with Candida tropicalis difference from unfermented crude rice husk hydrolysate and mono-cultured S. cerevisiae or C. tropicalis. Methodology and results: The effects of mono-and co-cultures S. cerevisiae with C. tropicalis on the nutrient compositions of distillers dried grain were investigated. The crude rice husk hydrolysate in distilled water contained molasses, urea, sodium nitrate, ammonium nitrate, potassium phosphate and magnesium sulfate heptahydrate were fermented by mono-and co-cultures of S. cerevisiae with C. tropicalis for 7 days at 28-30 °C and stored with a relative humidity of 60-70% in the dark. A mono-and a co-culture fermentation of S. cerevisiae and C. tropicalis increased the crude protein, crude fat, crude fibres, ash, and calcium contents of the rice husk feedstock and decreased the metabolic energy reducing sugars. Conclusion, significance and impact of study: Some nutrient components of the DDG crude rice husk hydrolysate performed higher than the non-fermentation of rice husks. The finding of this study will serve as a basic reference for future studies to utilize by-product of ethanol production from rice husks for animal feed formulation.

“…Yeasts have been cultivated also as rich sources of protein, minerals, vitamins (particularly B vitamins), and other nutrients for humans and animals (Wijeyaratne and Jayathilakf, 2000;Ouedraogo et al, 2017). Several yeast species have been used for biomass production, including Candida utilis, other non-methylotrophic Candida spp., Saccharomycopsis fibuligera, Kluyveromyces spp., and Saccharomyces cerevisiae (Dimova et al, 2010;Ouedraogo et al, 2017;Somda et al, 2017). Methylotrophic, ethanol-utilizing, and fat and hydrocarbon-utilizing yeasts including species of Candida, Ogataea, Pichia, and Trichosporon have also been used for biomass production (Türker, 2014).…”

Yeasts are the major producer of biotechnology products worldwide, exceeding production in capacity and economic incomes than other groups of industrial microorganisms. Yeasts have wide ranging fundamental and industrial importance in scientific, food, medical and agricultural sciences (Johnson, 2013). Traditionally, yeasts have been used for several fermentations such as alcoholic beverages, biomass production and other fermented food. Fermented foods and beverages play an important role in the diet of African people, and the most often, these foods and beverages are produced at household level or at small industrial scale and are consequently often of varying quality and stability (Mogmenga et al., 2017; Tankoano et al., 2017). In Africa, cereals, legumes and tuber roots are the major raw materials which are mostly fermented but milk, fish and meat are also used (Fguiri et al., 2012; Greppi et al., 2013; Akabanda et al., 2014). Depending to the country or even the locality, various names may be given to the same products that are basically similar with slight variations on production and raw materials. Various yeast species are often isolated from Africa foods and beverages fermentations, and some examples of previously reported species are Candida lusitania, Cryptococcus laurentii, Saccharomyces cerevisiae, Candida kefyr, Issatchenkia orientalis, Kazachstania unisporus, Rhodotorula mucilaginosa, Candida pararugosa, Torulaspora delbrueckii, Geotrichum sp., Kazachstania unisporus, Geotrichum fragrans, Yarrowia lipolytica, Trichosporon gracile, Pichia membranifaciens… For most reasons, yeasts are suitable for modern biotechnologies application. For example, yeasts offer the ease of microbial growth and gene manipulation allowed to understand many eukaryote-specific post-translational modifications, such as proteolytic processing, folding, disulfide bridge formation, and glycosylation (Cereghino and Cregg, 1999; Jans et al., 2017). Also, modern biotechnologies application of yeasts involve foreign proteins expressing for the pharmaceutical industry, the production of biofuel, organic acids, bioethanol, industrial enzymes, small molecular weight metabolites… (Türker, 2014). More recently, yeasts species including Pichia pastoris, Saccharomyces cerevisiae and others have been developed for heterologous proteins and enzymes production including pharmaceutical proteins, and as a model and fundamental organisms for the delineation of genes and their function in mammalian and human metabolism and disease processes (Cyert and Philpott, 2013; Johnson, 2013). New developments of yeast in engineering have introduced novel capabilities to extend substrate range and produce new products so far yeast can no produce. Saccharomyces cerevisiae is largest domesticated and still widely exploited yeast species in industrial today. This microorganism has become a valuable tool to study eukaryotic cell because he harbors many enzymes and pathways with counterparts in mammalian cells (Hatoum et al., 2012; Tomo et al., 2013; Mcfarland, ...
