  • Effective growth of dinoflagellate Prorocentrum minimum by cultivating the cells using municipal wastewater as nutrient source

    Several studies have been conducted worldwide in order to develop a more economical method for mass algal cultivation so that more cost-effective biomass production can be accessed. One of the directions is to reduce production costs by using wastewater as a nutrient source in algal cell cultivation. The growth ability of a red-tide causative dinoflagellate species, Prorocentrum minimum, in ...

  • Extent and rate of biodegradation of different organic components in municipal solid waste

    Rates and extent of biodegradability of four different organic components of municipal solid waste (leaf litter, newspaper, magazine paper and A4 sheet) were evaluated under optimum conditions. Total solids (TS) removals in biotic samples ranged from 74.7% to 78.8% while volatile solids removals ranged from 75.7% to 84.8%. Significant biodegradation of tannin–lignin was observed for all four ...

  • Identification of a suitable sterilisation method for collagen derived from a marine Demosponge

    Collagen is widely used as a biomedical material, and its importance is likely to grow as research and understanding progresses in this field. As a biomedical material, ensuring the sterility of collagen before use as, or incorporation into, a medical device is paramount. However, common sterilisation techniques can induce changes in the physical structure and protein chemistry of collagen, ...

  • Disruption of Synechocystis PCC 6803 for lipid extraction

    In order to extract intracellular lipids from cyanobacterial Synechocystis PCC 6803 for biofuel production, seven cell-disruption methods – autoclaving, bead beating, freeze drying, French press, microwave, pulsed electric fields (PEF), and ultrasound – were tested prior to lipid extraction to make intracellular lipids more accessible by organic solvents. The different methods brought about ...

  • Transformation of azo dyes during moist heat sterilisation: a potential source of error in microbial decolourisation

    This paper presents the role of moist heat sterilisation in decolourisation of azo dyes during autoclaving itself, thereby leading to over estimation of actual decolourisation through subsequent microbial process. This surprise phenomenon was probed in detail by studying the effects of temperature, pressure and role of electron donor/carbon sources on decolourisation. In the presence of 10 ...

  • Biotic and abiotic anaerobic transformations of trichloroethene and cis-1,2-dichloroethene in fractured sandstone

    A fractured sandstone aquifer at an industrial site in southern California is contaminated with trichloroethene (TCE) and cis- 1,2-dichloroethene (cis-DCE) to depths in excess of 244 m. Field monitoring data suggest thatTCEis undergoing reduction to cis- DCE and that additional attenuation is occurring. However, vinyl chloride (VC)andethenehavenotbeendetected in significant amounts, so that if ...

  • The biological removal of phosphorus from simulated wastewater using miniature bioreactors

    The objective of this study was to utilize miniature bioreactors in a laboratory-scale setting to biologically deplete excessive amounts of phosphorus (P). P occurring in wastewater is usually found in the form of phosphate (PO4). The potential for phosphate-removing bacteria (PRB) to overload significant levels of PO4 under aerobic/anaerobic conditions was observed and evaluated. Wastewater ...

  • Sources and levels of potentially toxic elements in the biodegradable fraction of autoclaved non-segregated household waste and its compost/digestate

    Waste that reflected the average UK composition of household waste was treated by autoclaving at the three set pressure/temperature levels of 2.7 bar/130 °C, 6.2 bar/160 °C and 15.5 bar/200 °C. The biodegradable fraction of the autoclaved household waste ('floc') was manually separated by screening and underwent characterization for its Cd, Cr, Cu, Pb, Hg, Ni, and Zn content. Autoclaving did not ...

  • Conventional and Alternative Technologies for the Treatment of Infectious Waste

    Abstract The limited scientific information about infectious waste, and the heightened public awareness of this special component of the waste stream, have contributed to the implementation or strengthening of the regulations in this area. This paper proposes a general working definition of infectious waste, and describes the systems used to limit its potential occupational and public health ...
