Abstract

Pediocin production by Pediococcus pentosaceus 2A2 was done in 30% molasses based medium at 37°C for 24 hours. The culture was then centrifuged to separate the cells and yield cell-free supernatant (CFS). Purification of the CFS was carried out by stepwise ammonium sulfate precipitation to achieve a 90% concentrate, followed by dialysis using membrane with a molecular weight cut off 2.0 kDa resulting in pediocin crude extract (PCE). The PCE was purified by cation exchange chromatography using SP Se-phadex C-25 and eluted with sodium acetat buffer at pH of 5.5; 6.0; 6.5; and 7.0 successively resulting in 4 fractions (F1, F2, F3, F4). Each purification step resulted in the increase in antimicrobial activity against Listeria monocytogenes ATCC 7644. The PCE had specific antimicrobial activity up to 5 fold higher than the CFS. F4 fraction, which showed the largest inhibition zone among the other fractions, had a very high specific activity up to 435 fold higher than the CFS. The SDS-PAGE analysis suggested that the molecular weight of F4 was approximately 5.9 kDa. The minimum inhibitory concentration (MIC) of F4 to inhibit 1 log (90%) of L. monocytogenes ATCC 7644 was 143 ppm. The inhibitory phenomenon observed under scanning electron microscope (SEM) showed that L. monocytogenes’s cells exposed to F4 experience morphological changes such as cells shrinkage.

Abstract

Pathogenic bacterial contamination found in fresh cow's milk can be caused by poor milking management. This traditional milking process allows the milk to be contaminated from bacteria and dirt. Dyeing dairy cows using a commercial antiseptic is a common measure that can be done to prevent mastitis. Nipple immersion can be done after milking using synthetic antiseptic agents such as povidone iodine and chlorine. However, the use of synthetic antiseptics can actually cause a slight irritation and allergic effect and leave a residue. Therefore, it is hoped that the use of natural-based antiseptics can replace synthetic antiseptics. One of the natural based antiseptics that can be used is bacteriocin. This research aimed to analyze the application of the plantaricin IIA-1A5 as a substitute for synthetic antibacterial for teat dipping before milking namely microbiological tests, physicochemical tests, and pH measurements. The study was conducted using a randomized block design (RBD) with three replications. The treatment design consisted of control (without immersion), plantaricin 0.0074%, and povidone iodine 0.2%. Results showed application of plantaricin IIA-1A5 as teat dipping before milking can reduce the Total Plate Count, Escherichia coli, and Staphylococcus aureus population. The use of plantaricin IIA-1A5 as teat dipping did not change pH value and physicochemical quality (fat, SNF, lactose, and protein), which is below the Indonesian National Standard (SNI) about fresh milk. This ability is comparable to the iodine group, a synthetic antibacterial widely used by smallholder breeders in Indonesia. It is concluded that plantaricin IIA-1A5 can be used as a substitute for synthetic antibacterial (iodine group) for teat dipping before milking.

Abstract

The free-range system is a currentmodel of chicken production according to the concept of Animal Welfare. This article aims to discuss how the free-range system was implemented and its effect on health, performance and quality product as well as free-range development strategies as an alternative to chicken production systems. The free-range system must have access to outdoor to express their natural behavior. Based on regulation, the density of chickens in outdoor is a maximum of 10,000 birds/ha. Chickens reared using the free-range system show better welfare indicators, as evidenced by the Heterophil/Lymphocyte (H/L) value and the frequency of their natural behavior. Chicken eggs from the free-range system contain higher levels of protein and carotenoid. It also contains omega-3 & 6, DHA, vitamins A and E and have lower cholesterol level. Chicken meat from the free-range system contains higher protein and lower fat levels. However, the performance of chicken production using free-range system was still not consistent and was greatly influenced by the type of forage in the pasture. The introduction of grazing land with superior forage such as Indigofera zollingeriana and choosing kampung or local type of chickens may become development strategies of chicken production in the free range system.

Abstract

Cemba (Albizia lebbeckoides [DC.] Benth.) leaf extract (CLE) was evaluated for some physical properties, antioxidant and antimicrobial activities incorporated into beef patties during cold storage. Four Formulation employed were control, butylated hydroxytoluene (BHT) 0.01, CLE 0.5, and CLE 1% (w/w). The variables measured were proximate composition, cooking parameters, pH, aw, WHC, color, total phenolic content, antioxidant capacity, DPPH scavenging activity, TBARS value, and microbial total. The data were analyzed using ANOVA one factor for proximate and cooking parameters, and ANOVA with factorial 4x5 for pH, aw, WHC, color, total phenolic content, antioxidant capacity, DPPH scavenging activity, TBARS value, and microbial total and continued with Tukey test. The results of the study showed that the addition of the CLE did not affect the proximate composition and cooking parameters of the patties. The cooked beef patties with 1% CLE showed significantly lower (P<0.05) for TBARS value, pH, bacterial total (mesophilic and psychrophilic) compared to 0.5% CLE and controls. The total phenolic content, antioxidant capacity, scavenging activity of CLE 1 % were significantly higher (P<0.05) than 0.5% CLE and controls during the cold storage period (0, 7, 14, 21, and 28 days). Addition of both 0.5 and 1% CLE in cooked beef patty reduced bacteria total. The addition of 1% CLE had equivalent to BHT 0.01% effect in retarding lipid oxidation. In conclusion, the CLE 1% was effective to retard lipid oxidation and inhibit bacteria growth of cooked beef patties.

Abstract

Yoghurt is a well-known fermented dairy product which produced using a combination of lactic acid bacteria (LAB) of Streptococcus thermophilus, Lactobacillus bulgaricus and L. acidophillus as fermentation starters. Cow milk is usually used as a raw ingredient. The LAB-based local yoghurt starter (S. thermophilus RRAM-01 (ST), L. bulgaricus RRAM-01 (LB) and L. acidophilus IIA-2B4 (LA)) were previously isolated from milk and meat, nevertheless had not been extensively attempted to be used in yoghurt production. This study aimed to evaluate the characteristics of cow and goat milk based yoghurt produced by using a single local strater of S. thermophilus RRAM-01 (ST) or L. bulgaricus RRAM-01 (LB) or L. acidophilus IIA-2B4 (LA). The yoghurts were produced through addition of the starter (3% v/v each) with 1010 CFU mL-1 of initial population, and then fermented at room temperature for 24 hr.  The result revealed that initial population of LAB in goat’s milk yoghurt fermented by ST or LB were significantly higher than that of by LA. Yet, after 24-hour of storage at room temperature, the total population of LA increased and reached final population which was higher than LB or ST. Meanwhile, cow’s milk yoghurt fermented by LB had the highest population of at the initial day (D0), while after fermentation the highest population were observed on LB or LA cow’s milk yoghurt. Overall goat’s milk yoghurt had significantly lower pH values than the cow’s milk yoghurt. These were accompanied by higher the total titrated acid (TTA) of goat’s milk yoghurt than that of cow’s milk yoghurt. Based on pH and TAT values, it was found that  ST bacteria produced significantly higher total acidity goat’s milk yoghurt, followed by LB and LA. However, the type of culture had no effect on total acidity of cow's milk yoghurt.

Abstract

The physicochemical characteristics and microbiological quality of buffalo meat are influenced by differences in muscle type. This study aimed to evaluate the physiochemical characteristic and microbiological quality of the topside (active muscle) and longissimus dorsi (passive muscle) of Indonesian local buffalo meat. Samples used in this study were buffalo meat from local swamp buffalo, aged more than four years old on the topside and longissimus dorsi. This study used a completely randomized design, with three repetitions in each treatment. All data were analyzed using analysis of variance (ANOVA). The result of the study on the topside and longissimus dorsi area showed a significant difference in the pH and cholesterol levels of the buffalo meat. The longissimus dorsi area had a lower level of pH and cholesterol compared to the topside area. Furthermore, this longissimus dorsi meat has a higher color, protein, ash, fat, essential amino acid, and lactic acid bacterial (BAL) content than the topside meat. However, the topside meat had higher carbohydrate, essential fatty acid, Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus) content compared to the longissimus dorsi meat. Longissimus dorsi meat had better physicochemical characteristics and microbiological quality than the topside meat

Abstract

The aim of this study was to identify the environmental factors of chickens based on the different altitudebreeding against the microclimatic and performance production in Takalar district, South Sulawesi. Atotal of 180 Lohmann strain chickens consisted of 90 male chickens and 90 female chickens. A randomizedblock design with two factorial patterns was used in this study. The first factor was based on altitude (low<300 mabove sea level, medium 300-600 m, and high >700 m ), the second factorwas based on gender(male and female). Data were analyzed using analysis of variance (ANOVA) and then the significant effectwas followed with Tukey test. The results showed that the altitudehad a significant effect against thephysiological status (rectal temperature), production performance (feed intake), water intake, final bodyweight, and FCR. The male and female chickens had a significant effect against feed intake, water intake,breeding final body weight, and carcass weight. There was interaction between altitude and sex on weightgain performances. The altitudes may influence the effects of physiological status and productionperformance. The production performance of male seems to behigher than the female.
