Utilization of bacterial nanocellulose (BNC) for large-scale applications is restricted by low productivity in static cultures and by the high cost of the medium. Fiber sludge, a waste stream from pulp and paper mills, was enzymatically hydrolyzed to sugar, which was used for the production of BNC by the submerged cultivation of Komagataeibacter xylinus. Compared with a synthetic glucose-based ...

Biofuels have received much attention recently owing to energy consumption and environmental concerns. Despite many of the technologies being technically feasible, the processes are often too costly to be commercially viable. The major stumbling block to full-scale production of algal biofuels is the cost of upstream and downstream processes and environmental impacts such as water footprint and...

Valorisation of agricultural wastes is one of the main objectives for activity optimization in agriculture industry. One method for waste utilization implies their use as substrate for obtaining edible mushrooms, which are a raw material of interest in current food industry. The aim of the paper was the cultivation of Pleurotus ostreatus var. florida species, on diverse common plant wastes. The...

ABSTRACT Lentinus tigrinus is a significant edible and medicinal mushroom. It was collected from University of the Punjab, Lahore under Morus tree. For domestication this wild species, its three parameters i.e., culturability, spawn production cultivation potential were assessed using different synthetic culture media substrates. Completely randomized design used to determine all effects evalua...

In general, morphological, physiological, and biochemical properties of fungal cells are drastically different among solid-state (SSC), liquid-surface (LSC), and submerged cultivation (SmC) systems. In addition to these traditional cultivation systems, a unique liquid-surface cultivation [liquid-surface immobilization (LSI)] system and interface cultivation systems [extractive liquid-surface im...

Biofuel and biochemical production by photosynthetic microorganisms such as cyanobacteria and algae is attractive to improve energy security and to reduce CO2 emission, contributing to the environmental problems such as global warming. Although biofuel production by photosynthetic microorganisms is called as the third generation biofuels, and significant innovation is necessary for the feasibil...

Two novel feather-degrading fungi belonging to Chrysosporium and Microsporum genus were isolated from poultry waste in Goa, India. The fungi produced extra cellular keratinolytic enzyme in a feather meal broth using chicken feather as a sole of carbon and nitrogen source. Maximum enzyme activity was obtained within 96 h (150 U/ml and 90 U/ml for Chrysosporium and Microsporum respectively) of cu...

Microalgae have gained enormous consideration from scientific community worldwide emerging as a viable feedstock for a renewable energy source virtually being carbon neutral, high lipid content, and comparatively more advantageous to other sources of biofuels. Although microalgae are seen as a valuable source in majority part of the world for production of biofuels and bioproducts, still they a...

The objectives of this study were to evaluate applicability of food waste compost (FWC) as a substrate for cultivation of Ganoderma lucidum, Lentinula edodes, and Pholiota adipose, and to determine contents of Ca, Mg, Na, and K in fruiting bodies (FB). FB yield per substrate in FWC-free controls was 53 ± 4 g/kg for G. lucidum, 270 ± 90 g/kg for L. edodes, and 1,430 ± 355 g/kg for P. adipose. Su...

A large amount of parasite biomass production necessitates a higher volume of culture media, and this further increases the overall cost. For this reason, novel and alternative culture supplementary materials have been continuously investigated. The aim of this study was therefore to evaluate the effect of cell-conditioned media, collected as waste material during routine cell culture, on the g...
