Biomass production from Bacillus sp. RAB9 using several carbon sources

Background The NYD medium (glucose, meat extract, yeast extract and peptone) is used for biomass production of some bacteria species that promote plant species growth [1-3]. The main carbon source present in this medium is the glucose that contributes a percentage of 25% to the medium price. An alternative to obtain a more accessible price for the medium is to replace the glucose by sources of lower cost. Several byproducts and feedstock from food industry and agro industry have been applied on microorganisms growth due your high availability and low cost. Among these, the molasses stands out as culture medium in fermentative processes because of your high contents of sugars, nitrogen and vitamins [4]. This study evaluated the replacement of glucose by comercial sucrose, soy molasses and sugar cane molasses seeking better conditions for biomass production from Bacillus sp. RAB9.
