“…All the species that NanoCrusta contains have been previously used for their probiotic effect in aquaculture (Balcázar et al, ; Carnevali et al, ; Wang, ). However, only three species were used as probiotics for zooplankton cultures: L. plantarum (Gatesoupe, ); L. casei (Planas et al, ); and B. subtilis (Giarma, Amanetidou, Toufexi, & Touraki, ; Motlagh, Farhangi, Rafiee, & Noori, ; Murillo & Villamil, ; Zink et al, ). The bacteria used in this work were previously reported to have beneficial outcomes when they are individually added to rotifer cultures such as promoting growth and reducing pathogens (Gatesoupe, ; Murillo & Villamil, ; Planas et al, ).…”

The effect of a commercial probiotic (NanoCrusta, Altacrusta, Mexico City, Mexico) on the growth performance of Brachionus calyciflorus Pallas, 1766, was evaluated. In a first approach, probiotics were supplied in four densities (2.0 × 103, 1.1 × 105, 2.1 × 105 and 2.1 × 106 cells/ml), alone and in combination with Chlorella vulgaris (1 × 106 cells/ml). The test rotifer did not grow on the probiotic alone. However, when probiotics + C. vulgaris were added, the maximum densities (Dmax; ind/ml) and population growth rates (r) observed were higher. In the second experiment, probiotics were supplied at five higher densities (2.1 × 106, 4.2 × 106, 8.5 × 106, 1.7 × 107 and 3.4 × 107 cells/ml) with C. vulgaris and a control treatment with only C. vulgaris (probiotic‐free). Treatments supplied with probiotics between 2.1 × 106 and 1.7 × 107 cells/ml showed significantly higher Dmax and r than the control treatment. The results showed a positive effect of probiotic bacteria when supplied with C. vulgaris. The best outcome showed a Dmax 2.16 times and an r 1.63 times higher than the density of the control treatment. Growth rates were higher in the treatments with probiotics compared to the control. We conclude that application of NanoCrusta is feasible to improve B. calyciflorus production, but the effects need to be tested in larger scales.

“…Improving the production of these enzymes with bacteria could improve the efficiency and reduce costs for the use of feather waste residues in the production of animal feed or cosmetics (Manczinger et al 2003;Mazotto et al 2011). Additionally, B. subtilis has been reported as a probiotic alone or in association with other bacteria, improving the immunologic response of rabbits and Artemia franciscana (Guo et al 2017;Giarma et al 2017).…”

Keratinolytic activity of Bacillus subtilis LFB-FIOCRUZ 1266 enhanced by whole-cell mutagenesis

et al. 2018

Discarded feathers represent an important residue from the poultry industry and are a rich source of keratin. Bacillus subtilis LFB-FIOCRUZ 1266, previously isolated from industrial poultry wastes, was used in this work and, through random mutation using ethyl methanesulfonate, ten strains were selected based on the size of their degradation halos. The feather degradation was increased to 115% and all selected mutants showed 1.4-to 2.4-fold increase in keratinolytic activity compared to their wild-type counterparts. The protein concentrations in the culture supernatants increased approximately 2.5 times, as a result of feather degradation. The mutants produced more sulfide than the wild-type bacteria that produced 0.45 µg/ml, while mutant D8 produced 1.45 µg/ml. The best pH for enzyme production and feather degradation was pH 8. Zymography showed differences in the intensity and molecular mass of some bands. The peptidase activity of the enzyme blend was predominantly inhibited by PMSF and EDTA, suggesting the presence of serine peptidases. HPTLC analysis evidenced few differences in band intensities of the amino acid profiles produced by the mutant peptidase activities. The mutants showed an increase in keratinolytic and peptidase activities, demonstrating their biotechnological potential to recycle feather and help to reduce the environmental impact.

“…LAB is recognized as a part of the microflora of rotifers (Gatesoupe, 1994), but its specific role is not yet fully understood. Applied to zooplankton cultures, B. subtilis acts as a growth promoter (Hirata et al, 1998;Murillo & Villamil, 2011;Zink et al, 2013); as a digestive enzyme promoter (Motlagh, Farhangi, Rafiee, & Noori, 2012); and as a pathogen inhibitor (Giarma et al, 2017;Murillo & Villamil, 2011).…”

Effect of commercial probiotic on the population dynamics of selected rotifers ( Brachionus angularis , Plationus patulus ) and cladocerans ( Moina cf. macrocopa and Simocephalus mixtus )

et al. 2020

In recent decades, an increasing interest in aquaculture for producing good quality and quantity of live food has led to the use of probiotics. Rotifers and cladocerans are important as live prey for fish and invertebrate larval rearing. We carried out an experimental study to evaluate the effect of a commercial probiotic (NanoCrusta®) on improving population growth of Brachionus angularis, Plationus patulus, Moina cf. macrocopa and Simocephalus mixtus. The probiotic was tested by direct supplementation (2.1 × 10 6 , 4.2 × 10 6 , 8.5 × 10 6 and 1.7 × 10 7 cells/ml) in addition to C. vulgaris as a source of food (1 × 10 6 cells/ml). The results indicated that probiotics enhanced maximum population density (D max) and the population growth rate (r) in both zooplankton groups. At 4.2 × 10 6 cells/ml, B. angularis improved their D max (62.74%) and r (28%) compared with probiotic-free control, while P. patulus enhanced their D max and r by 51.26% and 20.83% (probiotic at 8.5 × 10 6 cells/ml). The two lowest probiotic densities resulted in an improvement in the parameters compared with the probioticfree control treatments: M. cf. macrocopa enhanced D max by 14.82% and r by 18%, and S. mixtus incremented D max 10.92% and r by 10%. The addition of probiotic bacteria also resulted in an improvement in the rotifer egg ratio (ER).

Cultured zooplankton has benefits in contrast to naturally harvested zooplankton like more stable size, shape, availability, supply, nutritional quality and digestibility (Lubzens & Zmora, 2003). Microbial community management has a positive influence on developing better zooplankton culture conditions (Tang, Turk, &
