“…The results obtained showed that most of the major and mineral elements with the exception of phosphorus, magnesium and zinc were higher in the untreated sample. It is likely the microorganism might have use some of the minerals for their metabolic activities (Akinyele et al, 2011). This observation is consistent with the work of Frazier and Westhoff (1978) and Bannet et al, (2002) who reported that all living organisms require some mineral elements to maintain some metabolic functions.…”

Solid fermentation using celllolytic fungi: Pleurotus sajor-caju and Pleurotus florida for upgrading of sugarcane bagasse to value-added ruminant feed were investigated. The fermentation of the substrate lasted for 21 days after which the changes in the chemical and mineral composition, and the in vitro gas production were evaluated. The results obtained showed an increase in the crude protein (%) from 6.43 (control) to 9.82 for Pleurotus sajor treated substrate (PSB) and 10.05 for Pleurotus florida treated substrate (PFB). The treatment effect on crude fiber, neutral detergent fiber (NDF), acid detergent fiber (ADF) and acid detergent lignin (ADL) was significant. Fungal treatment decreased crude fiber (%) from 37.49 (control) to 31.67 (PFB), NDF (%) from 65.92 (control) to 53.34 (PSB), ADF (%) from 49.94 to 34.79 (PSB), and ADL (%) from 15.13 to 9.74 (PSB). Most of the major and trace minerals were higher in the untreated bagasse with the exception of phosphorus (0.15g/kg), magnesium (1.80g/kg), potassium (2.70g/kg) and zinc (21.60g/kg). The degradation of the insoluble but degradable fraction (b, ml) was higher in the control (19.00) followed by PSB (16.00). The estimated organic matter digestibility (%), short chain fatty acid (µ, mol) and metabolisable energy (MJ/Kg DM) increased from 38.77-50.06, 0.56-0.75 and 5.33-6.80 respectively. The gas volumes at 24h, 48h and 72h as affected by treatment was significant (P<0.05) with more volumes of gas produced in the treated bagasse. The result obtained in this study showed that fungal treatment of bagasse improved the nutrient contents and digestibility.

“…Many scientists have studied the role of different enzymes in the degradation process; degradation products formed by it and conditions affecting the degradation process (Novotný et al [2004]; Akinyele et al [2011]; Zhu et al [2013]). However, safety aspects of the process and products have not been reported so far.…”

Mushroom as a product and their role in mycoremediation

2014

View full text Add to dashboard Cite

Mushroom has been used for consumption as product for a long time due to their flavor and richness in protein. Mushrooms are also known as mycoremediation tool because of their use in remediation of different types of pollutants. Mycoremediation relies on the efficient enzymes, produced by mushroom, for the degradation of various types of substrate and pollutants. Besides waste degradation, mushroom produced a vendible product for consumption. However, sometimes they absorb the pollutant in their mycelium (biosorption process) and cannot be consumed due to absorbed toxicants. This article reviews the achievement and current status of mycoremediation technology based on mushroom cultivation for the remediation of waste and also emphasizes on the importance of mushroom as product. This critical review is also focused on the safety aspects of mushroom cultivation on waste.

“…The major limitation in the use of cassava starch extract pulp for monogastric animal feeding is its low protein content (Iyayi and Lossei, 2001). With the advent of biotechnological innovations many new avenues are opening up for their utilization (Akinyele et al, 2011). Cassava processing waste can be easily obtained in regions near processing plants due to the large amount of waste produced and the need for its disposal (Reginatto et al, 2011).…”

Cassava starch extract pulp is an important unconventional livestock feed rich in energy but rarely used as livestock feed due to anti-nutritional factor and lack of nutrient composition. Cassava starch extract pulp was detoxified by sun drying for two week due to high sun intensity and environmental temperature. Proximate and phytochemical composition, gross energy and cyanide contentof the pulp were determined using appropriate standard methods. The results of the analysis shows that the percentage moisture, crude protein, crude fibre, ether extract, ash, dry matter and gross energy of the pulp are 5.10%, 1.30%, 3.15%, 0.71%, 4.40%, 94.90% and 4328.72kcal/kg while its cyanide content were 37.58mg/kg. The results revealed that the pulp is very rich in energy. The nutritional content of the pulp were very low, however the ranges of values obtained are below the values that can adversely affected the nutritive value or cause any toxic effects in animal. Based on the results of the study, the pulp should be supplemented with other feed ingredients such as (methionine) which are the limited amino acid and those nutrients whose nutrients are very high.
