Abstract

The need of medicine product are increasing now. The fermentation of rice by using Monascus purpureus produce lovastatin, pigments and citrinin as secondary metabolites. The aim of this study was to know the concentration of lovastatin, red and yellow pigments and citrinin in rice which fermented by Monascus purpureus that had been mutated by using ultraviolet irradiation.Three strains were used in this research, such as AsK, yellow Jmba and red Jmba.The result were analyzed by using HPLC and Spectrofotometer. The result showed that the yellow Jmba strain which treated by UV mutagenesis for 3 minutes contain higher lovastatin (1.798%) and pigment and lower citrinin (0.019%) compare to without mutagenesis. On the other hand ASK strain produced higher lovastatin (1.903%) but higher citrinin (1.270%).This research is expected to provide scientific information to the public. That M. purpureus contained lovastatin that is beneficial, red and yellow pigments for natural food colorant.

Abstract

Bawean Deer {Axis kuhlii (Temminck, 1836)} is an endemic deer species from Bawean island, Indonesia. Under the National Protection act, the species is listed as protected and in the IUCN is categorized as Critically Endangered. In order to maintain the existence of these species, wildlife conservation of germplasm is needed through development of technique of sperm cryopreservation for Bawean deer semen. The sperm were collected from captive animals in Station for Beef Cattle Research Center, Ministry of Agriculture, at Grati, Pasuruan, which consisted of two adult males and two sub-adult males. The research objective was to determine the quality and quantity of preserved sperm from captive deer Bawean in the form of frozen semen for conservation needs and further usage. Prior to sperm collections, the animal was anesthetized with mixture of xylazine and ketamin. Sperm was then collected by an electroejaculator using a 2-cm probe diameter and 17 cm of length. Extender solution used was tris glycerol. The semen was able to be collected only from two adult stags with sperm motility of 50-60% and sperm concentration was in the range of 500-1140 x 106sel/ml. This study suggested the need for monitoring the developmentof sperm in relation to antler development.
