Laboratory Scale

Laboratory scale investigations have been made of the fermentative and other changes Which occur during the ensiling of heavily wilted lucerne and ryegrass in air-tight containers. Dry matter losses were small but increased with increasing moisture content and ensiling period. Lactic acid production was restricted and little, if any, was produced during four months' storage at the lower moisture content levels. In the ryegrass silage, the breakdown of protein, and the formation of ammonia were no greater than in good quality silage of normal moisture content.

Significant Difference

For ages, pure sugars or edible crops have produced lactic acid. However, a major concern on lactic acid production lies in the cost of the raw materials used. Thus, an alternative to overcome this situation is urgently needed. Characterization of banana peels shows that it contains promising sugar that can be utilized for lactic acid production, which are xylose (0.774 g/L), glucose (0.756 g/L) and fructose (0.532 g/L). Thus, this study aims to screen the potential of banana peel as a substrate by using Rhizopus oryzae through batch fermentation for lactic acid production, as R. oryzae can synthesize lactic acid in low nutrient requirements. Two-level factorial analysis was designed to screen the effects of moisture content (60% and 80%), temperature (27 °C and 40 °C), pH (4.5 and 6.5) and inoculum size (1x104 spores/mL and 1x108 spores/g) on the lactic acid production. Based on the Two-level factorial (2LF) analysis, the highest lactic acid production of 0.0813 g/L was detected at 80 % moisture content, pH 4.5, the temperature of 27 °C and inoculum size of 1x104 spores/g. The findings show that most of the conditions have a significant difference between each other (p<0.05). Therefore, the fermentation of banana peels by R. oryzae could be a promising method to produce a lactic acid concentration.

Concentrate Supplementation

Maxgrass is a silage additive consisting of a premixture of carboxylic acids containing ammonium hexamethanoate (68%) and ammonium hexapropanoate (10%). In theory, this additive when used on grass for ensiling at a high rate (6.0 1/t) should restrict fermentation, thereby reducing the level of VFA and lactic acid production and increasing the amount of residual WSC in the silage. It is claimed that silage with these characteristics should result in higher dry matter intakes and better animal performance. The objective of this experiment was to compare the performance of dairy cows fed either maxgrass or formic acid treated silages at two levels of concentrate supplementation.Silage was harvested unwilted from a primary growth sward of perennial ryegrass on May 21 and 22, 1990. The additive treatments applied through the harvester were: (i) Maxgrass - 6 1/t grass and (ii) formic acid - 2 1/t grass. Cows calving between mid-September 1990 and early January 1991 were used to evaluate the silages.

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.
