★ Yeast as a replacement for fishmeal in the diet of tilapia (Oreochromis niloticus) was evaluated in a clear water and a biofloc environment. Triplicate groups, each of 20 juvenile tilapia (initial weight of 29 ± 3.2 g), were randomly assigned to 24 conical 500-L tanks equipped with feed waste traps. Twelve of the tanks were in a recirculating aquaculture system (RAS) with clear water, with mechanical and biological filters and on average 15% daily replacement of water. The other 12 tanks were connected to four serial 10 m3 open biogenerator tanks that were initially fed with Bacillus subtilis and nutrients in order to achieve a C:N ratio of 10, supporting bacterial growth. In this biofloc system, only evaporated water was replaced. Four iso‑nitrogenous (35%) and isoenergetic (19 MJ kg-1) diets were formulated to contain graded levels of yeast where 0%, 30%, 60% and 100% of fishmeal protein was replaced by yeast. Fish were reared for 3 months, with hand-feeding twice a day, achieving at least a fivefold increase in weight. At the end of the experiment, feed intake, protein intake, weight gain, daily weight gain, specific growth rate, feed conversion ratio, protein efficiency ratio, survival rate and body indices of tilapia were determined. In fish reared in clear water there was a lower weight gain, daily weight gain and specific growth rate with replacement of fishmeal, but significant only in the 100% replacement group. Despite nearly identical feed and protein intake in both environments, significantly higher growth was observed in fish kept in the biofloc environment, accompanied by significantly improved feed conversion ratio and protein efficiency and reduced mortality. A significant decrease in entero-somatic and intestinal index with increasing level of dietary yeast was observed, but only in the clear water environment. No significant effects or trends were noted in any other body index data, either for yeast inclusion rates or water environments. Based on

🔸 Sodium hydroxide is a popular strong base used in industry. Sodium hydroxide is used in the manufacture of sodium salts and detergents, pH regulation, and organic synthesis. In bulk, it is most often handled as an aqueous solution, since solutions are cheaper and easier to handle.
Sodium hydroxide is used in many scenarios where it is desirable to increase the alkalinity of a mixture, or to neutralize acids.
For example, in the petroleum industry, sodium hydroxide is used as an additive in drilling mud to increase alkalinity in bentonite mud systems, to increase the mud viscosity, and to neutralize any acid gas (such as hydrogen sulfide and carbon dioxide) which may be encountered in the geological formation as drilling progresses.
Another use is in Salt spray testing where pH needs to be regulated. Sodium hydroxide is used with hydrochloric acid to balance pH. The resultant salt, NaCl, is the corrosive agent used in the standard neutral pH salt spray test.
Poor quality crude oil can be treated with sodium hydroxide to remove sulfurous impurities in a process known as caustic washing. As above, sodium hydroxide reacts with weak acids such as hydrogen sulfide and mercaptans to yield non-volatile sodium salts, which can be removed. The waste which is formed is toxic and difficult to deal with, and the process is banned in many countries because of this. In 2006, Trafigura used the process and then dumped the waste in Ivory Coast.

Other common uses of sodium hydroxide include:---
Chemical pulping.
Tissue digestion.
Dissolving amphoteric metals and compounds.
Esterification and transesterification reagent.
Food preparation.
Cleaning agent.
Water treatment.
Historical uses.
In cement mixes, mortars, concrete, grouts.
Experimental.
Flavonoids.
Neutron Moderator.
Summer-winter heat storage.
