“…PGPR are known to produce a wide variety of plant growth-promoting traits that include siderophores [ 10 , 11 ], phytohormones [ 12 , 13 ], hydrolytic enzymes [ 14 ], exopolysaccharide [ 15 , 16 , 17 ], stress-tolerant metabolites [ 18 , 19 , 20 , 21 ], and phosphate solubilization [ 22 , 23 ], etc. PGPR through these metabolites promotes seed germination, root and shoot growth, the level of soil and plant nutrients [ 13 , 21 , 24 ]. The beneficial effects of PGPR are sometimes not obtained due to various reasons such as the production of a limited number of plant growth-promoting (PGP) traits, competition with the native soil microflora, less root colonization, and sensitivity to biotic and abiotic stresses [ 2 , 3 , 20 ].…”

Bacteria that surround plant roots and exert beneficial effects on plant growth are known as plant growth-promoting rhizobacteria (PGPR). In addition to the plant growth-promotion, PGPR also imparts resistance against salinity and oxidative stress and needs to be studied. Such PGPR can function as dynamic bioinoculants under salinity conditions. The present study reports the isolation of phytase positive multifarious Klebsiella variicola SURYA6 isolated from wheat rhizosphere in Kolhapur, India. The isolate produced various plant growth-promoting (PGP), salinity ameliorating, and antioxidant traits. It produced organic acid, yielded a higher phosphorous solubilization index (9.3), maximum phytase activity (376.67 ± 2.77 U/mL), and copious amounts of siderophore (79.0%). The isolate also produced salt ameliorating traits such as indole acetic acid (78.45 ± 1.9 µg/mL), 1 aminocyclopropane-1-carboxylate deaminase (0.991 M/mg/h), and exopolysaccharides (32.2 ± 1.2 g/L). In addition to these, the isolate also produced higher activities of antioxidant enzymes like superoxide dismutase (13.86 IU/mg protein), catalase (0.053 IU/mg protein), and glutathione oxidase (22.12 µg/mg protein) at various salt levels. The isolate exhibited optimum growth and maximum secretion of these metabolites during the log-phase growth. It exhibited sensitivity to a wide range of antibiotics and did not produce hemolysis on blood agar, indicative of its non-pathogenic nature. The potential of K. variicola to produce copious amounts of various PGP, salt ameliorating, and antioxidant metabolites make it a potential bioinoculant for salinity stress management.

“…Supplementation of phytase to poultry diets improved poultry immune systems and increased weight (Daniel et al 2018). Adding phytase to young turkey had beneficial effects on their growth performance and tibia mineralization but had no effects on the carcass traits (Ciurescu et al 2020).…”

“…Phosphorus (P) in phytic acid is of very importance because it has high amount of P accounts to (28.2%), and poultry usage to phytate P is poor (Ravindran et al 2006). Phytase is an enzyme that initiates phosphate removal of from phytate and it has been widely used in animal feeding specifically in the poultry industry to increase phosphorus intake and minimize pollution of environment (Daniel et al 2018). Phytase is an enzyme that can hydrolyze phytate into inorganic P (Selle et al 2007), and because there is insufficient quantity or lack of intestinal secretion to phytase, large amounts of P are excreted in manure and feces causing environmental problems, especially in areas of intensive poultry enterprises.…”

Plant origin feeds contain some important nutrients that are not available to poultry due to their inability to analyze them and benefit from them. An experiment was fulfilled to study the performance of broiler chicken using supplemented diets with four levels of phytase enzyme 0.0 FTU/kg feed (T1), 500 FTU/kg feed (T2), 1000 FTU/kg feed (T3) and 1500 FTU/kg feed (T4). A completely randomized design (CRD) using four treatments, with three replicates each with 12 Ross 308 male chicks, was performed. Results indicated significant (P≤0.05) differences in feed intake (FI), body weight (BW) and feed conversion ratio (FCR). The highest feed consumption was recorded with (T1), where (T4) recorded the highest body weight and best FCR followed by (T3, T2 and T1) respectively. There were significant (P≤0.05) differences in carcasses, gastrointestinal tract (GIT) and the associated parts weights, and some GIT organs lengths. However, other parts including heads, necks, shanks and abdominal fat weights were non-significantly (P>0.05) different. There were no significant (P>0.05) differences in individual sensory evaluation attributes (taste, flavor, color and tenderness), but there were significant differences in overall sensory evaluation. There were no significant differences in the mortality rates among treatments. However, there were significant (P≤0.05) differences in the economics appraisal were (T4) recorded the least cost and the highest revenue. It reveals that using the (1500FTU/kg) level of phytase enzyme had performance parameters and economic appraisal. It could be concluded that supplementing broiler chicken diets with (1500FTU/kg) is good for production performance and returns.

“…It has numerous bene ts, including overcoming antinutritional factors such as phytic acid and enhancing digestion and gut ecology (Attia et al, 2020). Phytase primarily improved phytate phosphorus utilization, particularly in high phytic acid diets, as well as the utilization of protein/amino acids, energy, phosphorous, calcium, and other trace minerals (El-Enshasy et al, 2018). Another important group of exogenous poultry enzymes is Cellulases, which are hydrolyzing enzymes that hydrolyze the − 1,4-D-glucan linkages in cellulose to produce glucose, cellobiose, and oligosaccharides.…”

This study assessed the effects of high-fibre olive pomace (OP) and exogenous multi-enzyme (phytase, cellulase, and xylanase) on broiler chickens' growth performance, internal organs, intestinal morphology, blood traits, lipid profile of serum, and health. 300 one-day-old Ross 308 chicks were randomly divided into six groups using a 2 × 3 factorial design with 0 and 0.5g/kg multi-enzyme and 0, 5, and 10% olive pomace. The diet was primarily based on corn and soybean meal. The experiment was carried out in three stages: starter, grower, and finisher. The results indicated that the inclusion of OP at both 5% and 10% levels did not negatively impact broilers' performance (P > 0.05). However, supplementing the diet with multi-enzyme significantly increased feed consumption, body weight, and weight gain (P < 0.05). Furthermore, chickens offered with 10% OP + multi-enzyme exhibited the best performance compared to other experimental groups. The mortality rate also showed a non-significant decline of almost 5% (P > 0.05). Additionally, administration of OP and multi-enzyme or a combination of them to the broilers' diet improved serum lipid profile and liver enzyme activity (P < 0.05) and did not affect the relative weight and length of internal organs, and intestinal histomorphology (P > 0.05). In conclusion, simultaneous use of multi-enzyme and diet containing olive pomace could improve the serum lipid profile, liver enzyme activity, and overall health without adverse effect on broilers performance.
