Published: July 2021

When ammonia in waste water is lost inappropriately, it Â will raise an adverse environmental effect for the aquatic cycle.Â Anammox, anaerobic ammonia oxidation,Â is a novel process in which nitrite is used as an electron acceptor in the conversion of ammonium to nitrogen gas.Â The anammox process removes ammonium in the autrotrophicÂ system by leaving little biomass.Â This study aims to analyze the effect of salinity on the growth of anammox bacteria. The samples used were from the brackish water sediments of the East Flood Canal River of Semarang.Â The isolation was done by gram staining and the bacteria were inoculated on media with different salinity concentration and the growthÂ was measured using spectrophotometer.Â The results showed that anammox bacteria had a higher growth rate of 3% (control) when it was grown on a medium with a concentration of 9%. Anammox bacteria grown on anammox selective media showed that the bacteria were able to adapt to environments with different salinity concentrations of 2% and 9%.Â Key words: anammox, ammonium, nitrogen, anammox bacteria.

Reproductive biology is one of prominent studies in biomedical research. Disruption in reproductive system becomes a major problem both in humans and animals. Preclinical study using animal model is therefore needed to initiate clinical studies and diagnostic purposes. Wistar rats are commonly used for research in male and female reproductive system due to their representation of mammal biological system. For that purpose, their reproductive age must be determined to meet the aim of studies. This research was carried out to provide reproductive profile of normal male Wistar rats from different ages, furthermore categorizing them into three checkpoints: young, subadult, and adult. Variables observed including: body mass, testosterone level, reproductive glands index, spermatogenesis, and sperm analysis. Results demonstrated that body mass, testosterone level, and reproductive glands index increase with age (significant at the age of 6â€“7 weeks). Spermatogenesis is initiated at the age of 7 weeks, characterized by significant increase in the number of spermatogenic cells which then maintained at subsequent ages. Spermatozoa has been produced at the age of 6 weeks, however still in low concentration, immotile, and not viable. The quantity and quality of sperm also increase with age. At the age of 8â€“9 weeks, sperm concentration significantly increases, progressive movement occurs, and viability is close to 100 %. In conclusion, rats aged 4â€“5 weeks can be categorized as young, sexually immature; rats aged 6â€“7 weeks are subadult, the reproductive system has well-developed (puberty) but spermatozoa are still immotile (infertile); rats aged 8â€“9 weeks are adult, sexually mature, and ready for mating, thus suitable as animal model for the study of reproductive system.Key words: Wistar rats, reproductive system, testosterone, spermatogenesis, spermatozoa.Â

The mycorrhizas are â€˜balancedâ€™ mutualistic associations in which the fungus and plant exchange commodities required for their growth and survival. The are many type of mycorrhizal namely endomycorrhiza, ectomycorrhiza, Orchid-mycorrhiza, ericoid mycorrhiza, and ectendo mycorrhiza. Most research is in endo and ectomycorrhiza, due to their role in Papua. Research in mycorrhiza has also been done recently. The research started in 2005 with ectomycorrhiza studies conducted by Suharno & Sufaati. Study on endomycorrhiza were begin in 2006 and orchid mycorrhiza in 2007. Exploration study of endomycorrhiza in corn plant at Koya Barat showed that there were 7 species of VAM namely GlomusÂ sp1., Glomus sp2., GlomusÂ sp3., GigasporaÂ sp., Acaulospora., ScutellosporaÂ sp1., and ScutellosporaÂ sp2. Similar research have also been done on other agriculture comodity, and the weed as well. Study on the endomycorrhiza associated with matoa (Pometia pinnata) found 13 species. Furtheremore, preliminary research on ectomycorrhiza showed that at least four species have been found at Mount Cycloops Nature Reserve, Jayapura. In Papua, there were 18 strain isolate of Â Scleroderma have been collected and 4 species were already identified. For orchid-mycorrhiza there were only 17 species has been found so far. Among them there species were identified: RhizoctoniaÂ sp., TulasnellaÂ sp., dan CeratorhizaÂ sp. The potency of mycorrhiza in Papua is high and need to be explored. Some isolate were already tested to variety of the growth of plant. The result showed that the isolate affected significantly. More exploration, compatibility test, and the role of mycorrhiza will be continued to study. The goals of all the study here was to find a good quality of isolate that can be used as a propagule to produce biofertilizer.Key words: endomycorrhiza, ectomycorrhiza, orchid-mycorrhiza, biofertilizer, Papua.Â

The aim of study was to know the effect of Arbuscular Mycorrhiza Fungi (AMF), Glomus mosseae on the growth of onion Allium cepa L. on red-yellow podzolic soils. Completely Randomized Design (CRD) factorial with 10 replicates was used in this experiment. The first factor was mycorrhizae, with two level: without inoculation as a control (M0); 10 gram inoculation = M1). The second factorwas leaf litter of gamal Gliricidia sepium L. species Â Â wich were no litter as S0; 5 gram litter = S1; S2 was 10 gram of litter; and 20 grams of loitter in one kilogram of soil separately. Parameters used in this study were the growth of onion that has infected root in percent, and Relative Growth Rate (RGR). ANOVA was used to analyze the data, and followed with DMRT at 95% level test. The result showed that mycorrhizal inoculation increased root and shoot fresh weight, the dry weight of shoot; and the percentage of root infection on the onion. While the leaf litter of gamal increased only in leaf area. In contrast mycorrhizal inoculation and gamal leaf litter and their combination had no effect on other growth parameters.Â Key words: AMF, Glomus mosseae, Gliricidia sepium, Allium cepa.

Authors: Wijanarka Wijanarka , Pujiyanto Sri , Raharjo Budi
Published: July 2021

Glucanolitic bacteria are bacteria that have the ability to break down glucan into glucose monomer units. The ability of the bacteria is caused by the presence of glucanase enzymes. The choice of glucanase derived from bacteria is based on the ability and speed of bacterial growth in terms of producing glucanase enzymes. The presence of bacteria and protozoa in the digestive tract symbiotic with each other to digest cellulose or concomitant materials . Based on the ability of the way of life to digest forage and leaf litter, it is suspected that snails (Achatina fulica) have the ability to produce glucanase biocatalysts, especially in the digestive tract. To find out the characteristics and characteristics of indigenous bacteria snail canals, identification of KE-B6 bacteria is carried out molecularly so that accurate and accurate results are obtained. The Basic Alignment Search Tools BLAST results of KE-B6 bacterial isolates based on 16S rDNA sequence data with 27F (Forward) and 1492R (Reverse) primers showed that these bacterial isolates had homology of 99.64% to Serratia marcescens.Â Â Key words: bacteria, glucanolitic, A. fulica, Serratia marcescens.

Plants respond to various conditions in the surrounding environment, whether favorable conditions or vice versa. Abiotic and biotic factors affect plant responses such as temperature, humidity, salinity, insects and pathogens such as viruses and bacteria. Plants have a defense system in tolerancing stress from the surrounding environment, for example heat shock protein (HSP) is a chaperone protein that plays a role in plant defenses when experiencing stress to the temperature. HSP is classified into six families based on their molecular weight, namely HSP100, HSP90, HSP70, HSP60, HSP40, and small HSP. Each has a role in maintaining the stability of plant metabolism. HSP is especially important for correct protein refolding, preventing degradation and denaturation of protein. Key words: plants; chaperone; heat shock protein; refolding; protein denaturation.
