“…Selections of a low-cost substrate and a microbial strain with high activity are accepted as very important aspects in microbial fermentations [11][12][13]30]. In this study, these aspects were optimized for maximum lactic acid production.…”

The objective of this work was to perform production of L-lactic acid from starch-rich waste loquat kernels by newly isolated Rhizopus oryzae MBG-10 fungus. Loquat kernel flour (LKF) was used as substrate (mainly as carbon source). The most favorable conditions for L-lactic acid production were LKF concentration of 80 g/L, CaCO 3 concentration of 20 g/L, ammonium sulfate concentration of 3 g/L and incubation time of 108 h. Under these conditions, L-lactic acid and biomass concentrations were 45.4 and 8.2 g/L, respectively, and a-amylase activity was 81.6 U/mL. No significant pH changes were observed in the medium thanks to the buffering capacity of LKF. L-lactic acid could be produced in a single-stage from starch-rich LKF without prior saccharification by the fungus with high amylolytic enzyme activity. This is the first report on use of waste loquat kernels as a lactic acid production substrate.

Rhodotorula benthica is a unicellular yeast strain and presents widely in ocean with rich compositions of proteins, carotenoids, vitamins, digestive enzymes, and other biologically active substances. It has been applied in many fields including food, feed, medicine, and water industry. Rhodotorula species grow rapidly at 30 ℃ with coral pink, smooth, and moist to mucoid fettle, while the growth at 37 ℃ is variable. Rhodotorula species are strict aerobic yeasts with peculiarly metabolic characteristics. Rhodotorula produces urease and it has the inability to assimilate inositol and ferment sugars. Moreover, it is well known as a good source of carotenoids, proteins, essential amino-acids, digestive enzymes, lipids and vitamins. Rhodotorula benthica possesses a broad utilization prospect based on its metabolites, structures and bioactivities. This review summarizes some advances on the types, structures, and biological applications of the isolates from Rhodotorula glutinis.

“…The presence of a high concentration of salts increases the osmotic pressure in the cells and causes their disruption (Divya et al, 2011). However, studies, such as those conducted by Taskin et al (2011), show that elements, such as S and P, that are present in the fermentation substrate exhibit a protective effect toward the cell because these favor the formation of the phospholipid membrane and regulate the exchange of substances into the cell. Therefore, although we did not obtain the highest biomass levels with the ACR substrate, a protective effect in the cells was observed due to the consumption of certain elements that are present in this substrate.…”

1Xanthomonas albilineans is a pathogen that causes leaf scald disease in sugarcane (Saccharum officinarum L.) This disease causes the death of seedlings and consequently results in economic losses for sugarcane growers. The objective of this work was to isolate a lactic acid bacterium with antimicrobial activity against X. albilineans from sugarcane crops and to evaluate its antimicrobial activity and its lactic acid production kinetics, biomass yield, and substrate consumption in three different fermentation substrates. To isolate the lactic acid bacterium, samples were collected from different parts of infected and non-infected sugarcane plants of var. CC85-92. Lactococcus lactis ssp. lactis was isolated from the leaves of healthy crops, and showed in vitro antimicrobial activity against the pathogen. Batch fermentations of this isolate (at 32 ºC, agitation of 100 rpm, and pH 6) were performed using a commercial substrate (MRS), a commercial substrate supplemented with glucose (MRSG), and a substrate produced from agricultural crop residues (ACR). The highest antimicrobial activity was 5.83 mm in the ACR substrate after 6 h of fermentation. The maximum biomass production of 3.37 g L -1 and the maximum lactic acid production of 12.1 g L -1 were obtained in the MRSG substrate. The lactic acid production did not show any significant differences between the substrates. This lactic acid bacterium showed antimicrobial activity against X. albilineans and is thus a biological alternative for the control of leaf scald disease in sugarcane.
