Description
Technical field
The utility model belongs to photosynthetic bacteria culture technique field, specifically a kind of for cultivating the two of photosynthetic bacteria
With elbow test tube.
Background technique
Photosynthetic bacteria is that occur protokaryon generally existing, with original luminous energy synthetic system in earliest, nature on the earth
Biology, be it is a kind of using light as the energy, can under anaerobism illumination or aerobic dark condition using in nature organic matter, vulcanize
Object, ammonia etc. carry out photosynthetic microorganism as hydrogen donor and carbon source.
Photosynthetic bacteria vitality, adaptability are all very strong, during growth and breeding in energy decomposing organic matter and absorption water body
The noxious materials such as nitrite, sulfide, itself is nontoxic and pollution-free, is excellent water environment modifying agent；Photosynthetic bacterial thallus battalion
It supports and enriches, be excellent feed addictive；Photosynthetic bacteria is adaptable, can restrain oneself the organic wastewater of high concentration, to poison such as phenol, cyanogen
Object, which has, centainly to be endured and capacity of decomposition, has stronger decomposition and inversion ability.
When photosynthetic bacteria is cultivated in laboratory on a small scale, generally require strain prior to being enriched in test tube, then be forwarded to culture
It in the biggish glass container of the surface areas such as ware, is cultivated under illumination, the pollution of strain easily occurs during strain transfer.And
And universal test tube due to bore it is smaller, in light and Bacteria Culture often because culture solution surface area is too small, illumination is insufficient, or
It is depositional influence due to photosynthetic bacteria, causes light and the bacterial photosynthesis time under the training method shorter, raw
Long period is longer, breeding is slower.
Present patent application exactly proposes a kind of dual-purpose elbow test tube suitable for photosynthetic bacteria culture in this context,
The elbow test tube is slightly larger than common test tube again in the design of bore, facilitates the inoculation for cultivating biology and enrichment, it can be achieved that level
Or the training method placed vertically, it avoids photosynthetic bacteria and goes to dirt caused by the switching process of culture dish again after test tube enrichment
Dye problem.When the elbow test tube is horizontally arranged cultivation photosynthetic bacteria, culture solution will not contact test tube mouth, pollute, and
The illuminating area of light and bacterium in test tube can also effectively be increased, sufficient luminous energy and thermal energy are provided, light and bacterium are greatlyd save
The time of enrichment and cost；In daily management, the elbow test tube can be also placed in shaking table vertically and be shaken, help to precipitate
Photosynthetic bacteria, which floats, obtains illumination, keeps the good growth of bacterium cell.
Summary of the invention
The utility model is in view of the deficienciess of the prior art, propose a kind of suitable for the dual-purpose curved of photosynthetic bacteria culture
Head test tube.
The purpose of this utility model is realized by the following technical solutions:
A kind of dual-purpose elbow test tube suitable for photosynthetic bacteria culture, which is characterized in that the straight sections including elbow test tube
Point, test tube elbow and test tube plug, the lower surface of the straight-tube portion is plane, and elbow test tube can be placed horizontally on table top, In
Effectively increase liquid surface area in light and bacterium cultivating process, provides suitable illuminating area for the photosynthesis of light and bacterium；
One end of the straight-tube portion is 120 degree of spherical surfaces, and the other end is the test tube elbow, and the inclination angle of the test tube elbow is 60
Degree, it is ensured that liquid built in test tube will not flow out and easy to clean；The upper end of test tube elbow be straight tube and opening, beyond the Great Wall with test tube plug
Opening, not only prevents living contaminants, but also slow down the evaporation of culture medium moisture.
Further, the elbow test tube internal diameter is 30mm, the long 45mm of straight tube at the top of test tube elbow, and spherical diameter is
40mm。
The utility model has the beneficial effects that a kind of dual-purpose elbow suitable for photosynthetic bacteria culture provided by the utility model
Test tube, the elbow test tube in the design of bore again be slightly larger than common test tube, facilitate cultivate biology inoculation and enrichment, it can be achieved that
The training method being horizontally or vertically placed avoids photosynthetic bacteria and goes to the switching process of culture dish again after test tube enrichment and causes
Pollution problem.When the elbow test tube is horizontally arranged cultivation photosynthetic bacteria, culture solution will not contact test tube mouth, pollute,
And can also effectively increase the illuminating area of light and bacterium in test tube, sufficient luminous energy and thermal energy are provided, greatly save light and
The time of Enrichment of bacteria and cost；In daily management, the elbow test tube can be also placed in shaking table vertically and be shaken, it is heavy to help
The photosynthetic bacteria in shallow lake, which floats, obtains illumination, keeps the good growth of bacterium cell.
The utility model is described further with reference to the accompanying drawings and examples.
