Conventional culture media are expensive owing to their constituents. Thus, several studies have sought to develop and evaluate the efficacy of alternative, low-cost culture media, in most cases, using natural and easily accessible raw materials. The present study is a literature review, observing various formulations of culture media based on prod...

Most of the culture media used in bacterial growth is composed of complex ingredients, increasing the value of the product. This makes its acquisition unavailable by educational institutions without sufficient funding, making even more difficult the practical teaching of microbiology. Therefore, the development of an alternative medium of simple co...

... Soy extract has been used as a culture medium for the growth of lactic acid bacteria, in addition to the development of fermented products such as tofu and soy yogurt. The challenges in preparing a fermented soy-based probiotic drink are based on the ability of bacteria to grow and reach a minimum population compatible with a probiotic product and on maintaining the viability of microorganisms during the refrigerated storage of the product, as well as its prevalence in the digestive tract of the consumer and have good sensory acceptability (Delgado et al., 2019;Santos et al., 2022). ...
... Soybeans contain nine essential amino acids such as valine, tryptophan, threonine, phenylalanine, methionine, lysine, leucine, isoleucine, and histidine (Monte Singer et al., 2020). Previous studies have shown that soy-based products can serve as good sources of nutrients for the cultivation of various microorganisms, especially bacteria and fungi Uthayasooriyan et al., 2016;Shareef, 2019;Cruz et al., 2020). Similar results were obtained in this study, where B. subtilis grew very well in both media, SBA and NA. ...
