The aim of this research is to study the fermentation technique of coconut processed liquid waste by varying the inoculum concentration of Lactobacillus acidophilus bacteria for lactic acid production. This research was carried out in several steps, namely the first step was the inoculum cultivation process of Lactobacillus acidophilus bacteria, the second step was the fermentation process of coconut water with variations in the concentration of Lactobacillus acidophilus bacteria inoculum, namely 5%, 10% and 20%. Analysis of lactic acid products, pH, glucose, Total Dissolved Solid (TDS), Total Suspended Solid (TSS) and Volatile Suspended Solid (VSS). The variation in the concentration of Lactobacillus acidophilus bacteria inoculum 20% is the most optimum to produce total lactic acid for batch and continuous systems. The results of the correlation analysis for inoculum variations of 5%, 10% and 20% had a strong relationship with lactic acid production, decreased pH and decreased glucose levels. The greater the inoculum concentration, the greater the decrease in the TDS, TSS and VSS content.

AbstractThis in vitro study evaluated the protective effect of titanium tetrafluoride (TiF4) varnish and silver diamine fluoride (SDF) solution on the radiation-induced dentin caries. Bovine root dentin samples were irradiated (70 Gy) and treated as follows: (6 h): 4% TiF4 varnish; 5.42% NaF varnish; 30% SDF solution; placebo varnish; or untreated (negative control). Microcosm biofilm was produced from human dental biofilm (from patients with head-neck cancer) mixed with McBain saliva for the first 8 h. After 16 h and from day 2 to day 5, McBain saliva (0.2% sucrose) was replaced daily (37 °C, 5% CO2) (biological triplicate). Demineralization was quantified by transverse microradiography (TMR), while biofilm was analyzed by using viability, colony-forming units (CFU) counting and lactic acid production assays. The data were statistically analyzed by ANOVA (p < 0.05). TiF4 and SDF were able to reduce mineral loss compared to placebo and the negative control. TiF4 and SDF significantly reduced the biofilm viability compared to negative control. TiF4 significantly reduced the CFU count of total microorganism, while only SDF affected total streptococci and mutans streptococci counts. The varnishes induced a reduction in lactic acid production compared to the negative control. TiF4 and SDF may be good alternatives to control the development of radiation-induced dentin caries.
