Lipase produced by Aspergillus niger is widely used in various industries. In this study, extracellular lipase production from an industrial producing strain of A. niger was improved by medium optimization. The secondary carbon source, nitrogen source, and lipid were found to be the three most influential factors for lipase production by single-factor experiments. According to the statistical approach, the optimum values of three most influential parameters were determined: 10.5 g/L corn starch, 35.4 g/L soybean meal, and 10.9 g/L soybean oil. Using this optimum medium, the best lipase activity was obtained at 2,171 U/mL, which was 16.4% higher than using the initial medium. All these results confirmed the validity of the model. Furthermore, results of the Box-Behnken Design and quadratic models analysis indicated that the carbon to nitrogen (C/N) ratio significantly influenced the enzyme production, which also suggested that more attention should be paid to the C/N ratio for the optimization of enzyme production.

“…To optimize growth, toxin production, carbon, nitrogen and other nutrientslevels requires precise balancing (Gbolagade, 2006;Churchill, 1982). Physiochemical requirements of fungi are known to vary significantly within not only in genera but also strains of isolates (Stanbury et al 1995; Lilly and Barnett, 1951). There are no generalized conditions which are applicable to all the fungi.…”

“…and environmental factors include pH, temperature, incubation period (Thakur et al 2009). The requirement of above conditions varies from fungus to fungus depending upon the genera to which they belong (Stanbury, 1995). Optimization of such factors is necessary for obtaining highest yield of secondary metabolites.…”

Parthenium hysterophorus weeds are one of the major problems in almost all types of agricultural lands, forest lands, pastures, farmlands and disturbed land including roadsides. It is also responsible for health problems in human and animals besides loss to agriculture and ecosystems. It causes allergic respiratory problems, contact dermatitis and mutagenicity. The main strategy of Parthenium control is the use of chemical herbicides. The increasing side effects of chemical herbicide and growing resistance against them in weeds have attracted the attention of researchers to search for some novel herbicidal compounds from natural sources. A significant barrier in the mycoherbicide metabolites production is the development of an economically viable fermentation process. The production of these compounds is largely affected by certain parameters like pH, temperature, incubation days and media constituents etc. Adjustment of these parameters up to optimum level leads to maximum production of mycoherbicidal compounds. Therefore, the purpose of this study was to standardize physiochemical conditions (Nutrient media, pH, Temperature, and Incubation periods) for maximum production of mycoherbicidal metabolites from phytopathogenic fungi Fusarium sp. FGCCW#16 isolated from Parthenium hysterophorus weed. Fusarium sp FGCCW#16 grew well and produced optimum mycoherbicidal metabolites in Richard's broth medium at 25 to 28°C on the 21 studay of the incubation. The optimal growth, however, was obtained at pH 6. The results of this investigation indicated that cultural conditions like culture media as well as physical factors such as temperature, pH and incubation period greatly affected the growth and production of mycoherbicidal metabolites by Fusarium sp FGCCW#16.

Soil microbial communities are the most diverse group on earth possessing a plethora of activities useful to mankind. Fungal species in particular, produce secondary metabolites that are potential bioactive compounds. In the present study, fungal species isolated from the soils of Kolli Hills, Tamil Nadu were subjected to a primary screening for their antibacterial activity. Ten fungal strains were selected and their extracts were tested against pathogenic bacteria by disc diffusion method. The most efficient species identified as Chaetomium aureum showed remarkable inhibitory effect against the pathogenic bacteria tested and hence growth conditions such as culture medium, pH, temperature, incubation period and the minimal inhibitory concentration were standardized for the maximum production of the secondary metabolites.
