“…Thus, the variations in mycelial growth of L. edodes isolates evaluated by diameter, growth rate and mycelial density may be due to the type of used agricultural residue as the culture substrate (Kuijk et al, 2017); size of the agricultural waste particles used as substrate for the production of the biocomposite (Islam et al, 2018); and type of supplementation (Kirsch;Macedo;Teixeira, 2016;Andrade et al, 2013).…”

The demand for biodegradable composite has grown worldwide in recent years, mainly in order to reduce environmental contamination by structural materials produced from the oil industry. The objective of this study was to evaluate the growth of isolates from the edible mushroom “Shiitake” (Lentinula edodes) in substrate coconut powder-based supplemented with wheat bran, as well as to analyze the influence of fungi growing period and drying time of the colonized substrate on the mechanical properties of the composite, in order to produce a biodegradable composite. The mycelial density is not influenced by the type of hyphae of L. edodes. Drying of the composite does not influence the residual odor, depending on the isolate. The compressive strength and foam type of the fungal composite may be influenced by the culture period and type of hyphae, depending on the fungal isolate. The composites colonized by the L. edodes isolates presented higher mechanical resistance at 30 days of complete colonization. The coconut powder supplemented with wheat bran colonized by isolated fungi LED 96/18 is an ecological alternative in the packaging production considering its mechanical properties.

“…Other environmental parameters or physical conditions on the fungal mycelia formation during fermentation with culture medium composition could be associated with yield of EPS. The morphological nature, physicochemical parameters and various physiological activities on fungal mycelia in submerged cultures were strongly depended on the quantity of metabolites (Znidarsic and Pavko, 2001;Kirsch et al, 2016). The findings of Kim et al (2006) revealed that, characteristics of mycelia in submerged fermentation were influenced by culture conditions such as composition and initial pH of fermentation medium, age and size of inoculum, aeration rate, agitation speed and thus, affect yield of EPS.…”

Pleurotus spp. are white-rot fungi that utilize different agro-wastes to produce useful biologically active compounds. In this study, exopolysaccharides (EPS) were produced by Pleurotus pulmonarius in submerged culture supplemented with different agro-wastes. Functional groups in EPS were revealed using Fourier Transform-Infrared (FT-IR) spectroscopy. Antimicrobial activity of EPS was tested against microorganisms using agar well diffusion. Scavenging potentials of EPS was tested against 1, 1- diphenyl-2-picryhydrazyl (DPPH), hydroxyl (OH), iron (Fe 2+ ) and nitric oxide (NO) radicals. In vitro prebiotic activity of EPS was carried out. The highest yield (5.60 g/L) of EPS was produced by P. pulmonarius in submerged culture supplemented with groundnut shell (20.0 g/L). The functional groups in EPS were hydroxyl (-OH), methyl (-CH 3 ), ketone (-RCOH) and carbonyl group (-C=O). EPS displayed zones of inhibition (5.00–14.00 mm) against tested microorganisms. Scavenging activity of EPS ranged from 65.70-81.80% against DPPH. EPS supported the growth of Lactobacillus delbrueckii and Streptococcus thermophiles with values ranged from 3.04 × 10 4 –3.40 × 10 4 cfu/ml and 2.50 × 10 4 –2.81 × 10 4 cfu/ml, respectively. Submerged culture of P. pulmonarius with addition of agro-wastes enhanced yield of EPS. The EPS exhibited bio-functional properties like antimicrobial, antioxidant and prebiotic activities. Hence, agrowastes can be recycled in submerged fermentation with fungi to produce promising biomaterials for biopharmaceutical applications.

“…Among the factors that influence mycelial density can be mentioned: the availability of nutrients, such as carbon sources and / or supplementation (Kirsch;Macedo;Teixeira, 2016;Tudryn et al, 2018); type of substrate (Andrade et al, 2013) and culture temperature (Andrade et al, 2010). Considering that the whole bioassay was performed with the same type of substrate, supplementation and cultivated under the same environment and temperature conditions, the difference in mycelial density observed between the treatments was due to the fungal species, as reported by Haneef et al (2017).…”

Production and mechanical evaluation of biodegradable composites by white rot fungi

et al. 2018

The production of plastic packing grows worldwide, resulting in the accumulation of these materials in the environment due to improper disposal and problems related to degradation. Alternatively, composites produced with agricultural residues and filamentous fungi may exhibit physical and mechanical properties similar to or greater than expanded polystyrene, depending on the fungal species and substrate of the cultivation. In the literature, no reports were found on the use of coconut powder and edible fungi of white rot in the mechanical properties of composites. Thus, the objective of this work was to select fungal isolates and to evaluate the period of cultivation in the mechanical resistance of composites produced in coconut powder supplemented with wheat bran. The experimental design was completely randomized in a 5 x 3 factorial scheme corresponding to the cultivation of five edible fungal isolates (Pleurotus ostreatus: POS-W, POS-SP1, POS-98/38; Pleurotus eryngii: POS ER and Pycnoporus sanguineus: PS) and three culture periods after complete colonization of the substrate (15, 30 and 45 days), with four replications. The period of cultivation of the fungal isolates may influence in the composite mass loss and volume loss. The compressive strength and tenacity of the composite are influenced by the fungal isolate and the time of cultivation. The isolates of Pycnoporus sanguineus, Pleurotus ostreatus and P. eryngii present potential characteristics for the production of biodegradable composites.
