Schizophyllum commune is a widely distributed macrofungal species assorted with bioactivities. The specific objectives were evaluation of antibacterial and antioxidant properties, synthesis of exopolysaccharides and carbohydrates contents estimation of mycelial extract of S. commune under submerged condition. Methanolic extracts of identified S. commune showed highest FRS (92.59%), chelating effect on ferrous ion (79.36%), reducing power (1.844) activities at 16, 1.5, 16 mg/ml concentrations respectively (p<0.05). S. commune showed potent antibacterial activities (p<0.05) against four bacterial strains except against P. aeruginosa where no activity was observed. The maximum inhibition zone was exhibited against S. aureus (20.2 mm) and minimum inhibition was found against B. subtilis (5.0 mm). This study recorded the highest dry weight (9.33 g/L) and rate of average growth (1.33 g/L/day) of S. commune in glucose (p<0.05) medium but highest EPS (4.10 g/L) production was observed in xylose medium. Out of seven nitrogen sources, maximum mycelial yield (2.7 g/L), rate of average growth (0.38 g/L) and EPS (4.26 g/L) were recorded in yeast extract medium (p<0.05). In glucose (0.597 g/100g) and yeast extract (0.006 g/100g) medias, the maximum amount of total carbohydrate was obtained from the EPSs of S. commune. That’s why it may be an excellent source of human medicines.

Tomato is an edible fruit and vegetable of the tomato plant Solanum lycopersicum L. (Lycopersicon esculentum). It is the third most cultivated crop in the world. The vines grow to about 3 feet in height but have delicate stems that cause them to crawl hence they need to be supported. It is botanically classified as a berry, making it a fruit but culinary classifications make it a vegetable. 1,2 Varieties of tomatoes include beefsteak, plum, cherry, grape, campari, tomberries, and pear tomatoes. This berry is vulnerable to pests and diseases, but cultivars have been introduced to increase their resistance. 3,4,5,6 The also require crosspollination to propagate. They provide a great source of umami and savory flavour and are rich in vitamins and sugars, but they are low in fat and protein. They also contain carotenoids like beta-carotene, choline, lutein and lycopene that protect the eye. Tomatoes are rich in folate, calcium, phosphorus, potassium and vitamins A and C. 7 Commonly eaten raw in sandwiches and salads, tomatoes are also used to make soups and sauces. 6 In vitro studies of Devadas and colleagues demonstrated that consumption of tomatoes can decrease the risk of cancer, maintain healthy blood pressure, and, protect the eyes and skin, while easing constipation due to high fiber and water content. 8

“…Phytopathogens cause economic losses in terms of yield decrease, and raise human health concerns due to harmful phytopathogen metabolites that remain in fresh fruit and vegetables, as well as in different products obtained by fruits and vegetables processing. One of common fruit and vegetable phytopathogens is the genus Penicillium, known for infesting citrus fruits (Nunes et al, 2009), apples (Quagliaa et al, 2011), tomato (Kalyoncu et al, 2005) and other agricultural crops. Crop losses due to diseases caused by Penicillium spp.…”

Biological control is one of the best alternatives to pesticides as it avoids their weak points in plant disease control. In this study, the composition of cultivation medium for production of bioactive compounds by Bacillus subtilis ATCC 6633 was optimized. The produced bioactive compounds were tested against a phytopathogenic Penicillium sp. known for infesting different agricultural products and causing substantial crop losses. Antimicrobial activity assaying was carried out using the diffusion-disc method, and inhibition zone diameters were measured as direct indicators of antifungal activity. The response surface methodology (RSM) was used to evaluate the effects of different contents of initial nutrients (glycerol, NaNO 2 and K 2 HPO 4) in cultivation medium on inhibition zone diameter. Optimization was carried out using the desirability function method in order to maximize bioactive compounds yield and to minimize residual nutrients contents. The optimized concentrations of the selected nutrients in cultivation medium for production of bioactive compounds were: glycerol 20 g/l, NaNO 2 1 g/l and K 2 HPO 4 15 g/l.
