“…With reference to humidity, oat straw showed the highest value with 11.9%, followed by triticale straw with 9.1% and finally barley straw with 8.1% of moisture. Table 2 shows the results from other authors, where the values range from 5.35% to 9.10% [25][26][27]. Therefore, the moisture content showed by samples were favorable, because the ranges obtained in this investigation for the raw material are within the specifications for the manufacture of paper.…”

“…The sample that obtained the highest percentage of holocellulose was the triticale straw with 73%, which is very close to that reported by Vargas et al [28] for barley straw, which is of 73.8%. Table 2 shows the results of other authors, where the values range from 56.3% to 80.1% by holocellulose [25,26,[28][29][30][31]. This data is of great importance as the results are close to those found in some woods, these being the main raw material in the production of paper, which gives us an idea of the possible cellulose yield that will be obtained.…”

“…Barley straw is the sample that showed the highest percentage of protein with 10.3%, followed by triticale straw having 8.9% protein, and finally oat straw with 8.9% protein. According to the references, the values found range from 1.30% to 7.72% for straw [25][26][27]. The protein content in the samples is a good factor, because this type of compound will not affect the production of paper, since these are eliminated during the process of obtaining cellulose and paper.…”

The main objective of this work is supporting the use of sustainable solutions for the management and reuse of agricultural waste from the cereal harvest, such as oats, barley, and triticale, making sheets of artisan paper, innovating the process with the use of different proportions of cellulose obtained from straw residues. The physical and mechanical properties of the obtained sheets showed that basis weight (66–96 g/m2), thickness (19–300 μm), burst strength (68.9–103.4 kPa), burst index (0.81–1.35 kPam2/g) and bulk (2.52–3.12 cm3/g), were adequate. Based on what can be observed in the SEM images, it is possible to infer that straw has the function of supporting the sheets using combinations of barley straw and recycled paper. The result of the IR analysis indicated that the sheet with an increase in hydroxyl groups was that obtained with barley straw. Therefore, the treatment was efficient. These results were corroborated by X-ray diffraction analysis, in which the percentage of crystallinity of the barley straw paper was 37.1%. Finally, the results obtained indicated that the crystallinity is better in the sheets containing large amounts of barley straw. The sheet with the highest percentage of crystallinity was that which was made using 100% of barley straw, showing a 37.1 percentage of crystallinity, followed by the sheet made of 100% recycled paper, having a value of 34.4%.

“…Then, Figure 1 showed that P. ostreatus could grow in the presence of added nutshells with a radial growth rate of 0.684 cm d -1 , which was similar to the results obtained with barley straw extract agar. Albeit it is not easy to compare the structural and morphological conformation between nutshells and barley straw, they have similar chemical compositions, containing 55.7% [10] and 56.3% [34] of holocellulose, respectively, and referring in lignin content is 29.4% [10] and 19.2% [34], respectively.…”

Agricultural wastes are an environmental and economic problem that countries must strive to solve as soon as possible. White-rot fungi can take advantage of these wastes through an efficient process involving the bioconversion of lignocellulosic materials. Therefore, this work has used pine needles (Pinus pseudostrobus) and nutshells (Carya illinoinensis), relevant wastes in Mexico, as substrates for growing three fungal strains (Ganoderma lucidum, Lentinula edodes, and Pleurotus ostreatus) on PDA plates supplemented with these materials. Besides, the capacity to produce lignocellulolytic enzymes by these three fungi through solid-state fermentation has been evaluated using pine needles and nutshells along with barley straw. The relevant results suggest that nutshells are a potential substrate for growing G. lucidum (mycelial growth rate of 0.758 cm d -1 ). Albeit pine needles waste has allowed G. lucidum growth (0.402 cm d -1 ), L. edodes and P. ostreatus growth on PDA supplemented plates were not observed. Further to this, nutshells or pine needles combined with barley straw were used as substrates through solid-state fermentation to produce lignocellulolytic enzymes (cellulase, xylanase, and laccase). G. lucidum presented the highest cellulase productivity (3.03 ± 0.34 IU/gdm·d) using nutshells and barley straw (BS_NS) as substrates, while HIGHLIGHTS• Nutshells and pine needles are potential substrates for solid-state fermentation.• G. lucidum was able to use nutshells and pine need as substrates for growing.• G. lucidum produced the highest yield of lignocellulolytic enzymes.• L. edodes and P. ostreatus produce cellulases and xylanases less efficiently that G. lucidum.

Lentinula edodes, and Pleurotus ostreatus • Insert a highlight no longer than 85 characters.• G. lucidum can grow efficiently on nutshells or pine needles-PDA plates.•

“…Lane [38] determined that the nutrients provided in the medium could affect the biocontrol or biostimulant capacity of the agent. Different substrates have been used for Trichoderma spore production, including barley straw [39], wheat, rice, corn kernels [40] or a mixture of substrates, such as wheat straw, bran, cassava, potato starch and sugar beets [41,42], among others. In general, in our study, high yields, expressed as colony forming unit (CFU) g −1 , were assessed in all substrate mixtures tested; the yields increased both in 80% buckwheat husk + 20% rice and 70% buckwheat husks + 30% oats.…”

Role of Trichoderma aggressivum f. europaeum as Plant-Growth Promoter in Horticulture

et al. 2020

The main objective of this study was to determine the capacity of Trichoderma aggressivum f. europaeum to promote pepper and tomato seedling growth compared to that of T. saturnisporum, a species recently characterised as a biostimulant. Consequently, in vitro seed germination and seedling growth tests were performed under commercial plant nursery conditions. Additionally, the effects of different doses and a mixture of both species on seedling growth under plant nursery and subsequently under greenhouse conditions were determined. Furthermore, mass production of spores was determined in different substrates, and their siderophore and indole acetic acid production and phosphate (P) solubilisation capacity were also determined. Direct application of Trichoderma aggressivum f. europaeum to seeds in vitro neither increases the percentage of pepper and tomato seed germination nor improves their vigour index. However, substrate irrigation using different doses under commercial plant nursery conditions increases the quality of tomato and pepper seedlings. Tomato roots increased by 66.66% at doses of 106 spores per plant. Applying T. aggressivum f. europaeum or T. saturnisporum under plant nursery conditions added value to seedlings because their growth-promoting effect is maintained under greenhouse conditions up to three months after transplantation. The combined application of the two species had no beneficial effect in relation to that of the control. The present study demonstrates the biostimulant capacity of T. aggressivum f. europaeum in pepper and tomato plants under commercial plant nursery and greenhouse conditions.
