Abstract

Contamination of Aspergillus flavus can attacks food and feed ingredients, especially seeds during the storage. The using of biological agents, like microbes that have antifungal activity becomes a promising and important solution to be studied. This research aims to find out the antifungal activity of lactic acid bacteria (LAB) from digestive tract of “Kampung” chickens against the growing of A. flavus. Source of  the isolates are from colon, ventriculus, and crop. The inoculums of LAB which using were suspension of cell and cell free supernatant (CFS). There were 6 isolates of LAB (Bub1, Bub3, Bub4, V52, C51, and NNB) tested to obtain the potential of antifungal activity, by with well diffusion and and submerged culture method. The results showed that the 5 isolates suspension cell of LAB showed inhibitory zones, except Bub1, whereas all CFS LAB showed the inhibitory zones against the growth of A. flavus in MRSA medium.  Furthermore, antifungal activity of LAB against A. flavus to be observed by measuring the dry weight of the mycelium production, as well as the percentage of inhibition during the incubation period. All isolates of LAB, from suspension cell and CFS showing antifungal activity against growth of A. flavus. The Bub3 and NNB isolates, from suspension cell and CFS showed that the best antifungal activity compared to the others.

Abstract

Pb lead metal is one of marine pollution material that can accumulate on macroalga Padina australis. The purpose of this research is to know the accumulation of Pb on P.australis, the abundance, and to know the Pb content correlation with abundance on P. australis. Research conducted on February 2018 in Makassar marine waters. The results indicate that there is a difference of the metal content of Pb on P.australis in each station. The metal content of Pb on the station I was at the range 0,0964-0,1388 ppm, Station II 0,0496-0,1050 ppm, and Station III 0,0597-0,1035 ppm which has exceeded the waters standard limit set>0.008 ppm.  The high average Pb concentration on the station I because the station I was closer to the mainland of potentially greater influx of Pb heavy metals on macroalgae. P. australis abundance on a station I 92 individuals, II 152 individuals, and III 319 individuals. The data analysis result shows the value of significant correlations 0.384>0.05 that there is no correlation between the Pb concentrations with abundance but the direction of correlation indicates negative (-0331) which means that if the Pb concentration rises then  P. australis abundance will decrease.

Abstract

Coturnix coturnix japonica is one of quail the promising commodities to breding. Health management of poultry in livestock such as quail has problems related to the threat of disease from the environment. Diseases caused by disease agents attack birds resulting in morbidity and mortality so that farmers experience losses. This study aims to determine the effect of injection of two different antigens at different time frames on body weight gain, relative organ weight and erythrocyte profile in 5-month-old male quail. The study used an experimental method of completely randomized design (RAL) with animals as many as 28 male quails divided into 7 groups with 4 replications, namely K0: not injected with antigen, P1: injection SDMD 2%, P2: SDMD injection 2% and ND vaccine, P3 : injection ND and SDMD 2% in week 4, P4: injection vaccine ND, P5: injection SDMD 2% and SDMD 2%, P6: injection treatment ND vaccine and injection ND vaccine. Data obtained by body weight gain, relative organ weight, erythrocyte count, hemoglobin level and hematocrit value. Data were analyzed by Analysis of Variance (ANOVA) using MiniTab17. The results showed that organ weight gain, relative organ weight, heart, heart, pancreas, kidney, lung, spleen, erotrocyte count, hemoglobin level, and hematocrit value were not significantly different (P> 0.05) with control treatment so it can concluded that the effect of antigen injection does not affect the weight gain of organs, the relative weights of the liver, heart, pancreas, kidney, lungs, spleen, the number of erotrosites, hemoglobin levels, and hematocrit values.
