“…This favored growth of the microalga. The yeast extract has a total nitrogen content that is between 10% and 12% according to its product specifications which can contribute to production of compounds such as purines, pyrimidine and B vitamins that are necessary for growth of this microalga 36 . As mentioned above, further study of the effects of this nitrogen source on the growth and accumulation of metabolites in Galdieria sp.…”

A search for extremophile organisms producing bioactive compounds led us to isolate a microalga identified as Galdieria sp. USBA-GBX-832 from acidic thermal springs. We have cultured Galdieria sp. USBA-GBX-832 under autotrophic, mixotrophic and heterotrophic conditions and determined variations of its production of biomass, lipids and PUFAs. Greatest biomass and PUFA production occurred under mixotrophic and heterotrophic conditions, but the highest concentration of lipids occurred under autotrophic conditions. Effects of variations of carbon sources and temperature on biomass and lipid production were evaluated and factorial experiments were used to analyze the effects of substrate concentration, temperature, pH, and organic and inorganic nitrogen on biomass production, lipids and PUFAs. Production of biomass and lipids was significantly dependent on temperature and substrate concentration. Greatest accumulation of PUFAs occurred at the lowest temperature tested. PUFA profiles showed trace concentrations of arachidonic acid (C 20:4 ) and eicosapentaenoic acid (C 20:5 ). This is the first time synthesis of these acids has been reported in Galdieria . These findings demonstrate that under heterotrophic conditions this microalga’s lipid profile is significantly different from those observed in other species of this genus which indicates that the culture conditions evaluated are key determinants of these organisms’ responses to stress conditions and accumulation of these metabolites.

“…This value is not far from the one obtained with the nonoptimized conditions (25.55 ± 0.04 g/l) in our previous studies (Ngouénam et al [ 10 ]) in which we used not only the same lactic ferment but also the same carbon source; however, nitrogen source was yeast extract. Thus, the difference between these LA concentrations may be due to the richness of yeast extract in group B vitamins as reported by Gomez-Gomez et al [ 39 ].…”

Lactic acid (LA) is used in food, cosmetic, chemical, and pharmaceutical industries and has recently attracted much attention in the production of biodegradable polymers. The expensive substances including carbon and nitrogen sources involved in its fermentative synthesis and the increasing market demand of LA have prompted scientists to look for inexpensive raw materials from which it can be produced. This research was aimed at determining the optimum conditions of lactic acid (LA) production from pineapple by-products and an inexpensive nitrogen source using Lactiplantibacillus plantarum strain 4O8. After collection and preparation of the carbon source (pineapple by-products) and nitrogen sources (by-products from fish, chicken, and beer brewing industries), they were used for the formulation of 4 different media in terms of nitrogen sources. Then, the proximate compositions of promising nitrogen sources were determined. This was followed by the screening of factors (temperature, carbon source, nitrogen source, MgSO4, MnSO4, FeSO4, KH2PO4, and KHPO4) influencing the production of LA using the definitive plan. Lastly, the optimization process was done using the central composite design. The highest LA productions ( 14.64 ± 0.05 g / l and 13.4 ± 0.02 g / l ) were obtained in production medium supplemented with chicken and fish by-products, respectively, making them the most promising sources of nitrogen. The proximate analysis of these nitrogen sources revealed that their protein contents were 83.00 ± 1.41 % DM and 74.00 ± 1.41 % DM for chicken by-products and fish by-products, respectively. Concerning the screening of factors, temperature, nitrogen source, and carbon source were the factors that showed a major impact on LA production in the production medium containing chicken by-products as nitrogen source. A pineapple by-product concentration of 141.75 g/l, a nitrogen source volume of 108.99 ml/l, and a temperature of 30.89°C were recorded as the optimum conditions for LA production. The optimization led to a 2.73-fold increase in LA production when compared with the production medium without nitrogen source. According to these results, chicken by-products are a promising and an inexpensive nitrogen source that can be an alternative to yeast extract in lactic acid production.

“…strain USBA-018 as a culture medium for lactic acid production was demonstrated by Gomez-Gomez JA. group and AHE exhibited the production of large quantities of lactic acid as a low-cost substrate [6] . International Aloe Science Council determined that value of malic acid between 818 to 3,427 mg/L in Aloe vera gel preparations (solids, 105℃ nonvolatile: ≥ 0.46%), an average amount of 2,029 mg/L, in 2000.…”

Aloe vera extracts have antimicrobial and anti-fungal activities, which may be able to treat minor skin infections. In spite of these antimicrobial activities, the inner leaf gel containing acemannan: non-digestible polysaccharide, leads to fermentation with endophytic bacteria and results in bacterial growth promotion, while no short chain fatty acids were detected in the ether extract of the fermentation broth with the rind. Butyric acid was identified by GC/MSD analysis from ether extract of the gel fermentation broth, expecting multiple beneficial effects of butyric acid at intestinal and extra-intestinal level. Present investigation exhibits that daily intake of the butyric acid fermentation extract from Aloe vera inner gel with endophytic bacteria, may provide the possible potential preventive and therapeutic roles in human health.
