happy new year. hope new year = new econ, decreased elect bills, more time
-
i did a quick search N. alkalicus: lake and soil N. hamburgensis: soil N. vulgaris: water and soil N. winogradskyi: water and soil most likely N. hamburgensis can stay in water as well but didnt mention in that website do it quietly la.

good job. i seen the vularis but the rest didnt. will do some read up or perhaps ask my Prof or PhD seniors. hope to isolate some of them.
-
sad, i thought they would have something out. yeah, too much work and cost involved also la. if only i have access to the lab i used to work in, i could help grow something out, isolate it, express it, sequence it and compare it to genome database. sad i no longer work there. but i do believe some of the nitrobacter family were found in the sea. and some both on land and sea since they are very adaptive.
-
very true, i think i ever come across those with nitrobacter content in those bacteria supplements for our aquarium. do you have the source for all the genus's condition? it will good for us to manage to pinpoint those that were more favorable to our saltwater keeping condition. but still, we are not to be confused with their survival range and proliferation rate in contrast with their optimum condition for that particular strain or the whole family. or confused with just a particular strain with the whole family.
-
really? i read nitrobacter optimum culture condition is at pH 7.5-8.2. if didnt dift too far away from the optimal range. they will still survive, only growth is retarded. the degree of it being affected is depended on the degree of dift. perhaps different mode of carrying out expt. or perhaps, calibration out of range which is a common expt error in lab. and if its die below 32F, it will be more likely but C is very unlikely.

and to add, to minimize those bad bacteria, you must have knowledge of your tank stability. in a sense that you believe ur tank nitrobacter etc are more then those "nasty fellas". let this and adding food source, you will have lesser chance to get overwhelmed by the bad fellas. so how to tell ur tank more to the nitrobacter side? well, thats for your own judgement already. enjoy ur reefing. and lemon, if you need absolute HPLC grade ethanol 200proof, let me know. for friends since you gave me so much things. i have got too much.
-
this is backed by me as well. just to add to what lemon had said, though with enough food source and nutrient. i try to make this as layman as possibile. cell divisions(multiplication) is not unlimited, they are not immortal. eventually cells will slow down in division and dies off till their cell walls couldn't take it. just like ur wound gets harder to heal as u get older. so its best to add in new strain of bacteria from outer source from time to time. and bacterias outside the nitrobacter etc do need carbon source to boost themselves. example are yeast etc. it depends whether or not you regards those bacteria as bad bacteria or not. but for sure, i do strongly believe carbon source like ethanol(vodka), vinegar, sugar(lactose, xylose, glucose etc) will aid in bad bacteria growth. in my experience, whenever i add carbon source to my cell culture, it was always easier to get them contaiminated with other rubbish bac. so perhaps people could take this as note worthy.

hi a warm welcome to sgreef, as far as i know, currently dun think you can out source it locally.

so sad to see this everytime -
Sorry missed the the price. its $20 per frag with about 20 + polyps. thank you MOssrope for taking effort to pm me.
-
interested party please pm me. thanks for reading
-
Prefer to trade/exchange frags, make new friends if anyone found either one of these appealing and interested to trade, do pm me or post a picture here. thank you 1) Polar Ice Cap metallic blue center and brown skirt

5) green rhodatics mushrooms with purple patches $20 sorry for the blur picture, need to take at a slant position thus explaining the distortion
-
-
3) greenish gold paly. normal looking paly but what i like is the long skirt that goes with my wave. very fast grower. $15 per frag. about 10-20 polyps per frag
-
*priority given to those can get more and FCFS* and please do not give me a chance to remember who were the people who once piloted me 2) fire and ice variant frag, should be having 20-30 polyp per frag.
