“…Likewise, the plants of jatropha (Jatropha curcas) and karanja (Pongamia pinnata), which have received a great deal of attention recently due to their great potential for use in the production of biodiesel, are expected to generate huge quantity of residual deoiled seed cake (Achten et al 2008). In India alone, jatropha production is forecasted to generate approximately 1000 kg seed cake per hectare crop, while karanja plantations is estimated to produce around 0.145 million metric tons of defatted oilseed cake per annum (Doshi et al 2014). The disposal of defatted cake leftover after expelling oil from these oilseeds will be one of the major problem in coming years, since jatropha and karanja being non-edible crops and their seeds being toxic, these cakes cannot be used as cattle feed (Joshi and Khare 2011).…”

Purpose The seemingly harmful effect of chemical insecticides to the environment, plants and human health, has led to prominent role of entomopathogenic fungi (ENPF) as biopesticide. However, the success of ENPF as biocontrol agent depends on their amenability to easy and cheap mass multiplication. Solid state fermentation (SSF) has emerged as an appropriate technology for management of agro-industrial residues and for their value addition. In this study, the potentiality of agricultural by-products for mass multiplication of Beauveria bassiana was determined.Methods Two sets of SSF experiments with agricultural by-products [tea leaf waste, wheat bran, husk of rice, pigeon pea and urad, and seed cake of jatropha and pongamia] as substrates; one with fortification of nutrients, while other with no nutrient addition were performed. The substrates (200 g) were inoculated with B. bassiana spore suspension (1 9 10 8 spores/ml) and incubated at 28°C for 14 days. After the incubation period, B. bassiana spore concentrations were enumerated. Results Maximum spore production was observed in rice husk, while jatropha seed cake showed least spore production. Addition of nutrient supplements in the substrates showed slight (pongamia seed cake) to significant (rice husk, tea leaf waste) increase in spore production. The results showed constant increase in spore production with increase in C/N ratio of the substrates.Conclusions Mass production processes directly influences the cost, shelf life, virulence, and field efficacy of fungal pathogens. The results from this investigation are expected to pave the way towards commercialization of B. bassiana by augmenting the research in fungal mass production.

“…Flaxseed can be used as a source of nutritious food or to produce biofuels. Biomass is considered as a potential source of environmentally friendly, renewable and sustainable energy . Biomass can be used for producing biofuels, power generation and products that would otherwise be made from fossil fuels, which gives rise to air pollution and thus related environmental degradation issues.…”

Edible vegetable oil seeds are used to produce oil for human consumption and inedible vegetable oil seeds are used to produce biofuels; the residue cakes from the extraction process contain significant energy that can be utilised. This study is a continuation of previous work on oil extraction from flaxseed to produce biodiesel; herein, the residue cake from flaxseed was studied. Three different types of samples (powdered seeds, de‐oiled cake, and in situ transesterified cake of flaxseed) were torrefied (through slow pyrolysis), and the sample properties were characterized. The higher heating value (HHV=36.01±0.36 MJ kg−1) and bulk density (0.33±0.01 g cm−3) of the powdered seeds are higher compared to the other two samples (i.e. de‐oiled cake and in situ transesterified cake). The torrefied biomass was light weight losing its mechanical strength on treatment, making it easier to grind. It was observed that the biomass torrefied at 300 °C had a higher fraction of particles between sieve sizes (between 2.0 and 0.063 mm) compared to the biomass torrefied at 200 °C. The sieve sizes between 0.5 and 0.063 mm showed that more particles of the torrefied biomass treated at 300 °C were collected compared to that torrefied at 200 °C. Due to the loss of hydrogen and oxygen content and the removal of water, the carbon content in the torrefied biomass increased by 25.52, 24.51, and 22.69 % for the powdered seeds, de‐oiled cake, and in situ cake samples, respectively. The powdered seeds had a higher carbon and hydrogen content compared to the de‐oiled and in situ transesterified flaxseed cakes because the powdered seeds contained fatty acids. The powdered seeds had a higher concentration of CO2 gas liberated during treatment compared to the de‐oiled and in situ transesterified cakes. This was attributed to the powdered seeds having a higher concentration of volatile hydrocarbons and a lower ash content. It was observed that the energy ratios were reduced with respect to increasing temperature whereas the highest energy ratios were found for the powdered seeds.
