Desenvolvimento micelial de Lentinula edodes em meios de cultivo à base de diferentes substratos orgânicos

The radial mycelial growth of Lentinula edodes (Berk.) Pegler, strain LE-96/13, was studied in culture media prepared with organic residues extract, by using substrates prepared with pineapple (Ananas comosus (L.) Merril) crown, Astrocaryum aculeatum Meyer peel, Theobroma grandiflorum Schum shell, Musa sp. (genomic group AAB, subgroup Pacovan) peel, and Musa sp. (genomic group AAB, subgroup Prata) peel, with three supplementation levels with wheat bran (0, 10 and 20%), and incubated at 25ºC. The experimental design was totally randomized, in a 5×3 factorial scheme, adding up 15 treatments with 4 repetitions, and each repetition corresponding to a Petri dish. The diameter of the colony was evaluated daily during nine days of incubation. After that period, it was verified that the highest mycelial growth averages of strain LE-96/13 of L. edodes were found in culture media prepared with T. grandiflorum Schum shell (whose supplementation with wheat bran was favorable for Mushroom development) and A. aculeatum Meyer peel (whose supplementation did not favor the mycelial growth of L. edodes in relation to the medium not supplemented).

Composição mineral de substratos à base de resíduos de bananeira durante o cultivo de Pleurotus ostreatus

The objective of this study was to evaluate the mineral composition (macro e micronutrients) of the substrates [initial and residual (postharvest)] based on different combinations of waste (leaf, pseudo-stem and pseudostem + leaf) and banana cultivars - Musa spp. (Thap Maeo, Prata Anã, Pelipita and Caipira) during 49 days for the cultivation of POS 09/100 strain of P. ostreatus. It was verified that all of the substrates based on different combinations of waste and banana cultivars presented satisfactory amounts of nutrients for the cultivation of P. ostreatus, both in the initial phase of cultivation and in the end.

Resíduos de bananeira como substrato base para o cultivo in vitro de Coprinus comatus

Coprinus comatus is an edible and lignolitic fungus which has presented great potential for commercial use due to its easy development in the different residues, such as banana tree leave. Thus, the mycelial growth of Coprinus comatus in culture media based on leaves of Thap-Maeo, Prata-Anã, Pelipita and Caipira banana tree cultivars, supplemented with 20% of wheat, soy and rice brans, was evaluated. 7 mm-wide discs of CCO 01/01 strain of C. comatus were inoculated in the middle of Petri dishes containing culture medium, inside a laminar flow chamber. Next, the dishes were arranged totally at random inside an incubator at 25 ºC. The daily measurements of the mycelial growth began after 24 hours, until one of the treatments reached the borders of the Petri dish. According to the results obtained, we verified that there was not effect of the kind of supplementation for culture media based on Thap-Maeo, Prata-Anã and Pelipita; the best growth averages for culture media based on Caipira were provided by wheat and rice brans. Therefore, banana residues may be a viable and ecologically correct choice for the cultivation of C. comatus, especially for Thap-Maeo and Prata Anã sorts, which provided the best growth averages, regardless of the supplementation used.

Cultivo in vitro de Pleurotus ostreatus em resíduos de bananeira

The objective of this paper was to evaluate the mycelial growth of Pleurotus ostreatus (strain POS 09/100) in culture media based on different banana tree residues. The experimental design was totally randomized in 3 x 4 factorial scheme and consisted in three combinations of residues (pseudostem, leave and pseudostem + leave) and four banana tree cultivars (Thap Maeo, Prata Anã, Pelipita and Caipira), totalizing twelve treatments each with five repetitions, adding up sixty experimental units. Growth was measured every 24 hours until the mycelium of one of the treatments reached the border of the Petri dish, what occurred five days after the beginning of the experiment. The results obtained showed that all the combinations of banana tree residues were favorable to P. ostreatus mycelial growth, especially pseudostem + leaf of Pelipita, Thap maeo and Prata anã cultivars. Thus, the use of banana tree residues is viable for cultivation of P. ostreatus, and considered as an excellent alternative, besides reducing their disposal in the environment.
