Abstract/ Executive Summary:

The study were carried out to investigate the effect of different levels of wheat bran (0, 10, 20, 30 and 40%) as supplement with rice straw on the proximate composition of Pleurotus ostreatus. The highest moisture content (91.08%) was observed under 20% wheat bran with rice straw treatment where as the highest dry matter percentage (9.85) was observed in 40% wheat bran with rice straw treatment. The highest amount of protein (27.78%) but the lowest amount of lipid (3.24%) and carbohydrate (39.44%) were observed in 30% wheat bran with rice straw treatment. The highest crude fiber (23.38 %) and ash (8.12%) were observed in 10% wheat bran with rice straw treatment. The highest amount of lipid (5.08%) and carbohydrate (48.45%) were observed in 0% wheat bran with rice straw treatment. The highest percentage of phosphorus (0.986), potassium (1.37) and calcium (26.58 mg/100g) were found in 30% wheat bran with rice straw treatment. The highest amount of iron (44.54 mg/100g) and zinc (15.17 mg/100g) were found in 20% wheat bran with rice straw treatment.

Objectives:

To find out the effect of different levels of wheat bran supplements with rice straw on the proximate composition of oyster mushroom (Pleurotus ostreatus).

Methodology:

The experiment was carried out at the, Biochemistry laboratory and Mushroom Culture House (MCH) of the Department of Biochemistry, Sher-e-Bangla Agricultural University, Dhaka. Five different levels of wheat bran (T₁= 0% (Control), T₂= 10%, T₃= 20%, T₄=30%, T₅= 40%) were evaluated as the supplement to rice straw substrate of oyster mushroom. The experiment was laid out in Completely Randomized Design with three replications. The spawn packets preparation, sterilization, inoculation and incubation were done using the method described by Sarker et al. (2007). The weight of each spawn packet was 500 g. Two ends, opposite to each other of the upper position of polypropylene (PP) bag were cut in "D" shape with a blade and opened by removing the PP sheet. The opened surface of substrate was scraped slightly with a tea spoon for removing the thin whitish mycelial layer. Then the spawn packets were soaked in water for 15 minutes and invested to remove excess water for another 15 minutes. The packets of each type were placed separately on the floor of culture room and covered with newspaper. The moisture of the culture room was maintained 80-85% relative humidity by spraying water 3 times a day. The light around 300-500 lux and ventilation of culture house was maintained uniformly. The temperature of culture house was maintained 22°C to 25°C. The first primordia appeared 2-4 days after scribing depending upon the levels of supplement. The content of the available carbohydrate was determined by the following equation: Carbohydrate (g/l00g sample) = 100 - [(Moisture + Fat + Protein + Ash + Crude Fiber) g/100g]. Ash (%) content = Wt of ash × 100 / Wt. of sample taken. Total nitrogen was determined by using the standard Micro kjeldhal procedure of Association of Official Analytical Chemist and total crude protein was estimated by multiplying the nitrogen content by a factor of 6.25. Determination of Ca, Mg, K, Fe, Zn and P: The content of Ca, Mg, K, Fe, and P was estimated by Perchloric acid digestion method .

Achievement/Findings:

Among the treatments the highest amount of protein, nitrogen, phosphorus, potassium and calcium were observed in rice straw supplemented with 30% wheat bran. The highest amount of lipid and carbohydrate were observed in control treatment but the lowest amount of lipid and carbohydrate were observed in rice straw supplemented with 30% wheat bran. Therefore observing the nutritional composition it can be concluded that rice straw supplemented with 30% wheat bran is the best among the applied treatments for locally grown popular oyster mushroom variety in Bangladesh.
