Repetitive non-destructive milking of hydrocarbons from Botryococcus braunii

摘要: Global warming, the diminishing availability of fossil fuels and increasing expectations quality life are driving move towards renewable fuel sources. The production biofuel from Botryococcus braunii is a high potential carbon neutral resource which has recently gained increased interest. stores hydrocarbons within lipid based extracellular matrix (ECM), allowing continuous non-destructive extraction (milking) these without compromisation cellular integrity. This provides an alternate pathway to biofuels, with significantly reduced nutrient energy requirements. aim this review utilise current literature on B. available solvent technologies make informed recommendations required course action for furthering source energy. Solvent hexane, through sieve plate column, was found be most suited method repetitive hydrocarbon (milking). can provide efficiencies, simple downstream separation process, relatively low cost, shear stress offers added option pulsing further improvement mass transfer. Considering, concept still new literature, areas such as; race selection, milking frequency/period, recovery period, system design supplementation in early stages development, leaving much room improvement. As progression made fields more data becomes available, detailed feasibility study carried out, demonstrating as sustainable biofuel.
