Unlocking the growth potential: harnessing the power of synbiotics to enhance cultivation of Pleurotus spp.

Abstract

The oyster mushroom (Pleurotus spp.) is one of the most widely cultivated mushroom species globally. The present study investigated the effect of synbiotics on the growth and quality of Pleurotus ostreatus and Pleurotus pulmonarius. Different synbiotics formulations were applied by spraying mushroom samples daily and measuring their growth parameters, yield, biological efficiency, proximate composition, mineral content, total phenolic content (TPC), and diphenyl-1-picryl-hydrazyl (DPPH) radical scavenging activity. Results demonstrated that the most significant yield of oyster mushrooms was harvested from synbiotics sprayed with inulin and Lactobacillus casei (56.92 g). Likewise, the highest biological efficiency obtained with a similar synbiotic was 12.65%. Combining inulin and L. casei was the most effective method of improving the mushrooms’ growth performance and nutrient content in both samples. Furthermore, synbiotics that combined inulin and L. casei resulted in the highest TPC (20.550 mg gallic acid equivalent (GAE)/g dry extract (DE)) in white oyster mushrooms (P. ostreatus). In comparison, in grey mushroom (P. pulmonarius) the highest TPC was yielded by L. casei (1.098 mg GAE/g DE) followed by inulin and L. casei (1.079 mg GAE/g DE). The DPPH results indicated that the oyster mushroom could be an efficient antioxidant. The results revealed that applying synbiotics improved the mushrooms’ quality by increasing their antioxidant capacity with higher amounts of phenolic compounds and offering better health benefits with the increased levels of mineral elements. Together, these studies demonstrated the potential of using synbiotics as a biofertilizer, which is helpful for mushroom cultivation; therefore, it might solve the challenge of inconsistent quality mushroom growers face.

摘要

平菇(Pleurotus spp.)是全球最广泛栽培的蘑菇品种之一。本研究旨在探讨合生元对Pleurotus ostreatus和Pleurotus pulmonarius生长和品质的影响。通过每日对蘑菇样品喷洒不同浓度的合生元,测量其生长参数、产量、生物效率、近似成分、矿物质含量、总酚含量和二苯基-1-三硝基苯肼(DPPH)自由基清除活性。结果表明,使用喷洒菊粉和干酪乳杆菌的合生元,平菇的产量最高(56.92克),生物效率也最高(12.65%)。菊粉和干酪乳杆菌的组合最为高效,可以同时提高两种样品蘑菇的生长性能和营养成分。此外在白平菇(P. ostreatus)中,菊粉和干酪乳杆菌组合的合生元可产生最高的总酚含量(20.550 mg GAE/g DE),而在灰蘑菇(P. pulmonarius)中产生最高总酚含量的是干酪乳杆菌(1.098 mg GAE/g DE),其次是菊粉和干酪乳杆菌(1.079 mg GAE/g DE)。DPPH结果表明,平菇可以作为一种有效的抗氧化剂。综上,合生元可通过增加酚类化合物的含量来提高蘑菇的抗氧化能力,并通过增加矿物质元素的含量来提供更好的健康益处,从而提高了蘑菇的品质。上述研究证明了合生元作为一种生物肥料用于蘑菇栽培的应用潜力,是帮助蘑菇种植者解决质量不稳定的一个有效方案。
