“…One of the advantages of the fermentative process for the production of lactic acid is the possibility to start with several sources, such as sucrose, glucose, mannitol, fruit residues, glycerol and other sources (Gao et al, 2006;Göksungur et al, 2005;Marques et al, 2008;Silveira et al, 2010;Zhang and Vadlani, 2013). The hydrothermal process, in this sense, is limited to the use of glycerol, and its production should be linked to processes that generate large quantities of glycerol.…”

-The production of lactic acid from glycerol by means of the alkaline hydrothermal process was evaluated using high concentrations of glycerol. The operating conditions that influence the hydrothermal process were studied. Temperature (250 -280 °C), catalyst to glycerol molar ratio (0.05 to 0.15), and water to glycerol volumetric ratio (0.8 to 1.5) were evaluated, as well as the use of NaOH and KOH as catalysts. A concentration of lactic acid of 122 g/L was obtained at 260 °C, 0.04 NaOH to glycerol molar ratio, 1.0 water to glycerol volumetric ratio and 3 h of reaction using crude glycerol as raw material. The results showed higher lactic acid concentration and productivity than the fermentative process and the hydrothermal process carried out using low initial glycerol concentration.

“…Other options for the increased productivity include e.g. the addition of manganese, which is a constituent of lactate hydrogenase [48], whey protein hydrolyzate [49], malt combing nuts [49], corn steep liquor [50], fish hydrolyzates and other fishery by-products [51][52][53], hydrolyzed spent cells [54] or red lentil flour [55]. It is likely that this is one of the future trends in lactic acid production, i.e.…”

“…Accordingly, the disposal of fishery wastes greatly affects the local environment. For this reason, various types of reutilization of fishery wastes have been reported: Production of protein meals for animal feeds by ensilation [1]; fishery waste disposal by composting [2]; production of fish protein for animal feeds by fermentation [1,3]; processing of fish waste by low-cost fermentation using Aspergillus awamori [4]; recovery of chitin [5] and carotenoids [6] by shrimp waste ensilation; production of nutrients for lactate production by acid hydrolysis [7]; production of protein sources for lactic acid bacteria by ensilation of hydrolyzed fish viscera [8] and production of low-salt fish sauce by fast fermentation of squid processing by-products [9]. The fishery waste is also reutilized through the fishmeal production [10][11][12].…”

A scaled-up bioconversion of fishmeal wastewater (FMW) into liquid fertilizer was performed five times in a 1 m 3 reactor in order to examine the feasibility of commercialization. The importance of aeration was marked. Analyses indicated that dissolved oxygen (DO) level was closely related to the value of oxidation-reduction potential (ORP) and it was crucial to achieve high-quality liquid fertilizer. When pure oxygen was supplied through four diffusers into the reactor, DO levels and ORP values were maintained over 1.2 mg/L and 0.2 mV, respectively all the time during 52 hr of bioconversion. The pH changed from 6.8 to 5.9. The average removal percentages of chemical oxygen demand (COD Cr ) and total nitrogen (TN) were 75.0% and 71.6%, respectively. Compared to the result acquired in a 5-L reactor, bioconversion of FMW into liquid fertilizer was achieved in a shorter time under the same removal percentages of COD Cr and TN. The 52-hr culture of inoculated FMW was phytotoxic-free and it possessed comparable fertilizing ability to a liquid fertilizer made from the fish waste in hydroponic culture with amino acid contents of 5.93 g/ 100 g sample. From all the above results, transferring labscale data to large-scale production appeared to be successful. As a result, the commercialization of a liquid fertilizer made from FMW was feasible.
