“…Moreover, the instability during storage caused by the high lipid content also hinders its use (Cheng et al, 2016). To address these problems, previous studies focused on different techniques such as fermentation (Omarini et al, 2019), the use of enzymes (Dadalt et al, 2015), the use of microorganisms (Supriyati et al, 2015), and processing (Zare‐Sheibani et al, 2015) to maximize the utilization of RB.…”

The study aimed to determine the effect of Limosilactobacillus equigenerosi and Ligilactobacillus equi as inoculants for solid‐state fermentation (SSF) in the proximate composition of nutrients and organic acid profile of rice bran (RB). The RB was treated with distilled water (DW) without inoculant (control), L. equigenerosi (T1), L. equi (T2), and L. equigenerosi and L. equi 1:1 (v:v) (T3). For the treatments, 90 mL of culture was pelleted and suspended with DW. Each treatment was replicated three times and incubated for 4, 7, and 10 days at 37°C. The crude protein, ether extract, crude ash, crude fiber, neutral detergent fiber, and acid detergent fiber were increased (P < 0.05) in fermented RB. The lactate and total organic acid produced were increased by the addition of lactic acid bacteria (LAB) (P < 0.01), and the highest concentrations were recorded in treatments containing L. equi (T2 and T3). Acetate production in T1 was highest than in control, T2, and T3 (P < 0.01). The results showed that LAB isolated from horse feces in combination with SSF can improve the quality of RB as an ingredient for animal feed based on the higher concentrations of protein, carbohydrates, minerals, and organic acids.

“…Changes such as the formation of complexes insoluble in the stomach and small intestine involving phosphorus, calcium, amino acids and fats, increased endogenous losses of minerals and amino acids, reduced activity of Na-K-ATPase in the TGI, and inhibition of enzymes such as trypsin and 𝛼-amylase were attributed to phytic acid, resulting in reduced nutrient utilization, increased maintenance protein and energy costs and reduced energy availability for production (Dersjant-Li et al,2015). As an alternative exogenous phytase enzyme, it is commonly used in monogastric feed, improving performance (Dersjant- Li et al, 2018) and digestibility of energy and nitrogen (Dadalt et al, 2015) in growing pigs. Nonetheless, this study presents the hypothesis that there is an effect of phytase on the fraction of phytic acid of corn and soybean meal diets containing DDGS considering that it has been little investigated (Swiatkiewicz et al, 2016, Woyengo et al 2016, Coelho et al, 2019 and not conclusive, which can be a strategy to improve the energy and balance the performance of growing pigs.…”

This study aimed to evaluate the effects of phytase enzyme and distillers dried grains with solubles (DDGS) on the digestibility, performance and economic viability of growing pigs. Two experiments were conducted with a reference diet (RD) based on corn and soybean meal: RD with 200 g kg -1 DDGS (DDGS); RD + 1,000 units of phytase (PHY); and RD + 200 g kg-1 DDGS + 1,000 units of phytase (D+P). In experiment 1, eight castrated male pigs weighing 29.35 ± 5.74 kg were used through the total collection method and replicates in time for digestibility evaluation. In experiment 2, 40 castrated male pigs 47.65 ± 3.99 kg, with five replicates of two animals per experimental unit, were used for performance and economic evaluation. DDGS increased the excretion of nitrogen and energy in feces and urine, impairing the digestibility coefficients and metabolizability of dietary energy. The animals that consumed diets with DDGS presented the worst performance, while phytase did not influence the results. Diets with the inclusion of 200 g kg -1 DDGS and 1,000 units of phytase did not differ in cost per kilogram compared to the control diet.

Production, characterization and applications of two distinct phytases from Thermomyces lanuginosus SSBP

Phosphorous (P) is an essential element which is primarily stored as phytic acid in plants and exits as dominating form of organic P in soil. The phytate anion has strong chelation properties and can bind with essential metal ions, proteins, starch and several biomolecules under physiological conditions, and accumulates in soil due to strong binding with soil solid phase. Phytases are enzymes that hydrolyse phytate in stepwise manner to release inositol phosphates and orthophosphate, thereby releasing the chelated molecule. In this study, we report two phytases (Tlphy1 and Tlphy2) from a thermophilic compost-dwelling filamentous fungus, Thermomyces lanuginosus SSBP. The total phytase production was enhanced by 8.56-fold in submerged fermentation after statistical optimization, which was further improved in fed-batch cultivations. Tlphy1 and Tlphy2 were purified to homogeneity with an overall purification of 24.7- and 18.7-fold with 5.16% and 6.4% yield, respectively. Tlphy1 was estimated to be 49 kDa and was optimally active at 55°C and pH 5.0, while Tlphy2 was purified as a 60 kDa protein showing optimal activity at 50°C and pH 2.5. Tlphy1 and Tlphy2 were stable over wide ranges of pH and temperature with a half-life of 138.6 and 58.72 min, respectively at 70°C. The applicability of these phytases was investigated for the improvement of bioethanol production using Colocasia esculenta, dephytinisation of a local non-alcoholic beverage, mageu and in improving growth promotion of common bean plants. Tlphy1 reduced phytate content in Colocasia esculenta starch from 1.43 mg/g to 0.05 mg/g that resulted in an improvement in the availability of fermentable sugars with a concomitant reduction in viscosity and 1.59-fold improvement in ethanol production. Supplementation of 50 U Tlphy2 in 100 g of mageu efficiently reduced the total fermentation time from 24 h to 16 h with significant dephytinisation and marked enhancement of essential metal ions. Additionally, Tlphy2 also promoted germination of bean seeds, while an enzyme dose of 25 U markedly improved root and shoot length of bean plants. Overall, the two distinct phytases from T. lanuginosus SSBP have multifarious applicability, and therefore can be of major interest to several biotechnological industries.
